What is TechOps?
TechOps at Kraken is a modern, lean evolution of traditional enterprise IT. We span everything from hands-on frontline support through to high-impact technical projects and long-term strategic improvements.
We are building a small, highly effective TechOps team and are looking for an ambitious, experienced TechOps Generalist to help us scale Kraken safely, securely, and with a strong focus on people.
This is a broad role with a huge amount of variety. You’ll work across identity, devices, SaaS, networking, automation, and office infrastructure - often at the same time. Ambiguity is a constant, and we’re looking for someone who enjoys making sense of it and turning it into action.
We operate almost entirely in the cloud, so you’ll be exposed to a wide range of modern tools and technologies across the business.

Why we're hiring: The Head of Infrastructure, Data & Technology Solutions is responsible for establishing and coordinating the infrastructure standards, operating model, governance, and cross-cutting platform capabilities required to run DTS products securely, reliably and consistently. DTS operates a federated model, where specialist product and platform teams retain autonomy for how they build, deploy and operate their own environments. The Head of Infrastructure ensures those teams operate within a common set of DTS standards for reliability, observability, security, deployment control, cost visibility, operational readiness and resilience. The role will work closely with the CTO, Chief Architect, SVP Data Collaboration Infrastructure, SVP Security and Compliance, TechOps, Engineering, Product, Enterprise Technology and platform leads across InfoSum, Open Intelligence, Resolve and other DTS capabilities. The purpose of the role is to create alignment and visibility across infrastructure and providing the autonomy needed by specialist teams to operate according to agreed standards and principles. What you'll be doing: 1. Infrastructure standards and operating model Define and maintain the common infrastructure standards that DTS platforms must meet. This includes: * Working with DTS leadership to define infrastructure principles, minimum standards and operating expectations. * Establishing standards for reliability, observability, deployment governance, security, resilience, cost visibility and operational readiness. * Ensuring standards are practical and can be adopted by different DTS platform teams. * Creating a clear infrastructure operating model that distinguishes between central standards and product-team autonomy. * Ensuring infrastructure standards are aligned with DTS architecture, security, product and commercial priorities. 1. Federated infrastructure governance Coordinate a federated infrastructure model across DTS. This includes: * Ensuring InfoSum, Open Intelligence, Resolve and other platform teams can operate their own infrastructure while meeting common DTS requirements. * Avoiding unnecessary centralisation that would slow down specialist teams or remove useful autonomy. * Defining where common tooling or central coordination is required. * Ensuring each product/platform team has clear infrastructure ownership and accountability. * Creating mechanisms to monitor whether teams are operating within agreed standards. 1. Alignment with DTS leadership Ensure infrastructure decisions are aligned with senior DTS leadership and broader platform strategy. This includes: * Taking direction from the CTO, Chief Architect, SVP Data Collaboration Infrastructure and SVP Security and Compliance on infrastructure priorities. * Translating DTS architecture and security principles into practical infrastructure standards. * Working with DTS leaders to resolve trade-offs between autonomy, standardisation, cost, security and reliability. * Ensuring infrastructure decisions support the wider DTS platform direction. * Providing leadership with visibility of infrastructure risks, gaps, dependencies and progress. 1. Deployment governance and change visibility Create common deployment governance and production change visibility across DTS. This includes: * Defining minimum standards for production deployment processes. * Establishing central visibility of who deployed what, when and where. * Supporting release gates, change records and deployment auditability. * Enabling teams to use their own deployment tooling while reporting into a common deployment record. * Supporting mechanisms to pause or control deployments during high-risk or sensitive periods. * Ensuring deployment activity can be correlated with incidents, outages and platform instability. 1. Observability,monitoringand operational visibility Define common observability and monitoring expectations across DTS platforms. This includes: * Establishing standards for logging, metrics, tracing, alerting and dashboards. * Ensuring product teams provide the right operational and security telemetry. * Supporting cross-platform visibility for incidents, chained attacks, service degradation and performance issues. * Working with Security Operations on SIEM, SOC and threat detection requirements. * Ensuring infrastructure and application events are visible to the right operational teams. 1. Reliability,resilienceand operational readiness Ensure DTS platforms meet agreed reliability and resilience expectations. This includes: * Defining standards for service-level objectives, availability, recovery, incident readiness and operational maturity. * Working with platform teams to ensure services are designed and operated to appropriate reliability levels. * Supporting disaster recovery, business continuity and operational readiness requirements. * Ensuring teams have appropriate runbooks, escalation paths and incident response processes. * Tracking recurring operational issues and ensuring they are addressed through the appropriate teams. 1. Infrastructure security alignment Work with Security and Compliance to ensure infrastructure standards support DTS security requirements. This includes: * Ensuring infrastructure standards reflect security requirements around access control, network exposure, ingress/egress, secrets, logging and hardening. * Working with the Cloud and Platform Security Lead where applicable. * Ensuring teams provide evidence that required infrastructure security controls are in place. * Supporting the reduction of unnecessary public exposure across DTS services. * Ensuring infrastructure governance supports audit, compliance and client assurance requirements. 1. Cost visibility and capacity oversight Establish infrastructure cost transparency and capacity visibility across DTS. This includes: * Defining standards for cloud cost reporting and allocation. * Ensuring teams can report infrastructure cost by product, platform, client or workload where appropriate. * Identifying areas of duplication, waste or inefficient infrastructure use. * Supporting capacity planning across growing DTS platforms and AI/data workloads. * Providing leadership with clear visibility of infrastructure cost drivers and optimisation opportunities. 1. Relationship with TechOps Work closely with the TechOps function while maintaining clear ownership boundaries. TechOps is responsible for day-to-day delivery operations, environment support, release coordination and operational support to engineering teams. The Head of Infrastructure is responsible for defining infrastructure standards, governance, shared visibility, reliability expectations and cross-DTS platform coordination. This includes: * Partnering with TechOps to ensure infrastructure standards are practical in delivery workflows. * Using TechOps feedback to identify recurring operational issues and improvement opportunities. * Avoiding duplication of TechOps responsibilities. * Ensuring delivery operations and infrastructure governance operate as a joined-up capability. * Clarifying when issues should be handled by TechOps, product engineering, infrastructure teams, security or DTS leadership. 1. Common tooling and shared platform capabilities Identify and coordinate shared tooling where it benefits DTS. This includes: * Assessing where common tooling should be used for deployment governance, observability, incident management, cost reporting, infrastructure inventory and operational reporting. * Avoiding unnecessary standardisation where teams need specialist tooling. * Supporting common integration points rather than forcing all teams onto identical infrastructure stacks. * Defining central capabilities that allow teams to remain autonomous while providing DTS-wide visibility. * Working with Architecture and Infrastructure teams to introduce shared services where there is clear value. Who you'll be working with: The Head of Infrastructure will be accountable for: * Common DTS infrastructure standards and operating model. * Federated infrastructure governance across DTS platforms. * Alignment of infrastructure activity with DTS leadership direction. * Deployment governance and production change visibility. * Observability, monitoring and operational visibility standards. * Reliability, resilience and operational readiness expectations. * Infrastructure cost visibility and reporting. * Clear distinction and partnership between Infrastructure and TechOps. * Infrastructure alignment with DTS architecture, security and compliance requirements. * Ensuring platform teams retain autonomy while meeting common DTS standards.

In February 2025, we secured $42 million in Series B funding. Now we’re scaling up across the business, and it’s an exciting time to join. Our people are the driving force behind everything we do. At Sparta, you’ll be trusted to take ownership, backed by a team who wants you to succeed. You’ll be challenged, supported, and given room to grow. Because building something this ambitious takes everyone at their best. At Sparta, your work has reach. From improving our platform, to powering smarter decisions for our customers, to changing how commodity trading is done around the world. And because we’re growing fast, you won’t just build your career. You’ll accelerate it, with a level of ownership and impact you simply don’t get at bigger, more bureaucratic companies. About the role As the TechOps Engineering lead you own and set the direction for the team that owns internal technology that enables and protects the company : internal tooling, security, identity and access, devices, networking and day-to-day support. You're the technical owner of our workplace technology — hands-on, but also setting the standards and processes and choosing technologies. You’ll work closely with our infra teams that run our production systems, you're comfortable around cloud and networking (AWS, VPNs, DNS); you’re an engineer at heart. The role spans both ends of the spectrum. You'll plan and shape our tech roadmap, standards, budget and vendors — and you'll also be genuinely hands-on, because no task is too small: some days that means redesigning how our internal VPNs should work, other days it's boxing up a laptop to post to a new joiner or managing a security incident. You're happy doing both. What you and your team will do: Identity & access * Own our Microsoft Entra ID (Microsoft Identity) tenant: identity lifecycle (joiners-movers-leavers), SSO, Conditional Access, MFA, groups and least-privilege access reviews. * Manage AWS access federated to Entra ID via IAM Identity Center. Devices & endpoints * Own device management through Microsoft Intune: provisioning/Autopilot, compliance and security baselines, patching, and asset tracking across laptops and mobile. * Administer Apple Business Manager and the hardware procurement/e-commerce portal— automated device enrolment (ADE) into Intune, Managed Apple IDs, app/content (VPP) licences, and ordering of Apple devices and accessories. Microsoft 365 & SaaS administration * Administer Microsoft 365 (Exchange Online / Outlook, Teams, SharePoint and OneDrive)- mailboxes, distribution/security groups, licences and tenant configuration. * Administer the rest of the toolchain — Atlassian (Jira/Confluence), Slack, GitHub —including licences, integrations and cost. Onboarding & offboarding * Deliver a smooth, secure joiner/leaver experience end to end (Entra accounts, Intune-enrolled hardware, M365 mailbox, VPN, app access). Networking & connectivity * Manage office network, Wi-Fi and VPN access; troubleshoot connectivity for on-site and remote staff. Support & operations * Be the senior escalation point for internal technical support; resolve the hard tickets and prevent the repeat ones. * Keep runbooks and documentation current; automate recurring toil with scripting. * Handle the practical, hands-on side of TechOps: sourcing peripherals and accessories, preparing, shipping and tracking hardware for remote staff, and keeping equipment stock. Planning & strategy * Plan and own TechOps staffing, roadmap, standards, budget and vendor/licence relationships, and improve processes as the company grows. Security & compliance * Own our internal security. * Enforce access, MFA and endpoint-hardening standards through Entra ID + Intune; support audits and access-control requirements. What we're looking for (essential) * 5+ years in techops operations / workplace technology, including senior/lead- level ownership. You’ve seen what good looks like. * Hands-on Microsoft Entra ID (Microsoft Identity) administration— SSO, ConditionalAccess, MFA, identity lifecycle.Strong Microsoft Intune (endpoint management) and Microsoft 365 / Exchange Online administration. * Solid networking fundamentals — DNS, VPNs, Wi-Fi, firewalls. * Comfortable around cloud (AWS) — IAM, IAM Identity Center, basic infrastructure concepts— even if you're not building it. * Scripting/automation (PowerShell, Bash or Python, PowerAutomate), ideally against the Microsoft Graph API. * Equally at home planning and owning techops strategy and getting hands-on with thepractical, sometimes mundane tasks — no job too big or too small. * Excellent communication and a genuine service mindset; calm and methodical under pressure. Nice to have * AWS depth (IAM Identity Center, Organizations, SSM) and exposure to an engineering CI/CD toolchain (GitHub, CircleCI). * Microsoft certifications (e.g. MD-102, MS-102, AZ-104) or equivalent. * Experience in a regulated / financial-data environment. Environment & tools Microsoft Entra ID (Microsoft Identity) · Microsoft 365 / Exchange Online · Microsoft Intune · Apple Business Manager · AWS (IAM Identity Center) · Atlassian (Jira/Confluence) · Slack · GitHub · VPN · an engineering-heavy user base.
