Mobile and Backend Software Engineer - Banking

Capital on Tap

We’re Capital on Tap 👋 💳 Capital on Tap started because small businesses were underserved. Big banks were slow, their products weren't fit for purpose, and small business owners often couldn't access what they needed. We set out to fix that. Today we're a financial platform - not just a credit card company. We offer a best-in-class business credit card, SME-focused spend management platform, a savings product that hit £1 billion in funds within its first year, and a growing suite of tools and financial products that make running a small business easier.  1,000+ employees, £20bn in annual card spend, 200,000+ customers, 17,000+ Trustpilot reviews averaging 4.7 stars, and we're profitable. We’ve done a pretty good job so far, but we’re just getting started!  🏡🏢This is a hybrid role, our engineering teams work from our London (Moorgate) Office 2 days per week. The Role We're looking for Senior Software Engineers to help us build the products that small businesses across the UK and US rely on every day. You'll work across cross-functional teams alongside Product Managers, QA Engineers, and fellow Software Engineers, owning problems end to end, from the first line of code through to production, monitoring, and continuous improvement. This isn't a role for someone who wants to be handed a ticket and told what to build. We're looking for engineers who understand the problem, challenge the approach when it needs it, and take pride in the quality of what they ship. We only build what the customer wants. What You’ll Be Doing * Designing and building robust, scalable solutions in .Net/C#, taking full ownership of the SDLC from concept through to production * Playing an active role in architectural decisions and technical direction, shaping how things are built, not just building them * Working closely with Product and QA, bringing your technical perspective early and often * Writing bulletproof unit and integration tests and holding a high bar for code quality across the team * Communicating clearly across technical and non-technical stakeholders, translating complex engineering decisions into business context * Mentoring and supporting engineers around you, raising the standard of the team as well as your own output We’re Looking For 🔎 Required skills: * 5+ years of hands-on experience in C#, .Net and SQL Server; React and Typescript are a strong plus * A clear sense of what senior means. Not just years in the seat, but ownership, judgement, and the ability to operate with ambiguity * Strong testing practices across unit and integration testing * Broad engineering knowledge that goes beyond your core stack; the kind of depth and curiosity that comes from solving hard problems in complex, distributed systems * The ability to communicate clearly and confidently, with your team, with Product, and with the wider business * Experience working in agile, cross-functional teams * Someone who's proactive, direct, and makes the people around them better Our Tech Stack * Backend: C#, .Net, .Net Core * Frontend: React, Typescript * Mobile: Flutter, Dart * Databases: SQL Server, MongoDB * Cloud: Azure & GCP Interview Process 🤝 * First stage: 30-minute intro, CV review, and values with a Talent Partner * Second stage: 45-minute “Tech Chat” with a Team Manager * Final stage: 90-minute Code Pairing + 30-minute Values Interview Diversity & Inclusion 🌈 We welcome, consider and encourage applications from anyone who shares our commitment to inclusivity. Join us in creating a space where authenticity thrives, and everyone can do their best work.

As VP, Business Technology, you will own the platforms and tools that power how our people work, every day. Reporting to the CIO, you will lead a team responsible for the business systems, collaboration platforms, AI and productivity tooling, end-user technology services, and the internal platform engineering capability that will underpin how automation is built and scaled across Genius Sports.  This is a hands-on engineering and leadership role. You will shape the strategy, own the vendor relationships, and drive the shift from a traditional IT function to a proactive platform engineering team that builds the automation infrastructure the business runs on. You bring real engineering depth alongside the commercial and stakeholder instincts the role demands.  Key Responsibilities  Own the Business Systems Portfolio  * Lead the strategy, roadmap, and day-to-day operations for Genius Sports' core business systems, including Salesforce, Atlassian (Jira and Confluence), Zendesk, and Microsoft 365.  * Define the integration architecture between business systems and enterprise platforms, ensuring data flows cleanly between tools without creating operational debt.  * Manage vendor relationships in close partnership with Strategic Sourcing.  * Own the Workday integration layer, working with HR and Finance system owners to ensure data integrity and operational reliability across connected platforms. Position the team as a trusted integration partner as broader Workday ownership evolves.   Build and Own the Internal Platform Engineering Capability  * Architect and build the internal automation platform that will underpin how Genius Sports automates workflows, integrates systems, and delivers self-service capabilities across the business. This is not a buy-only function: you will be building.  * Own the IaC and DevOps practices for the Business Technology estate, using Terraform, CI/CD pipelines, and infrastructure-as-code standards to ensure platform environments are version-controlled, auditable, and scalable.  * Lead the design and deployment of agentic automation workflows, including integrations built on MCP Servers, AWS Bedrock, Zapier, and API-layer connectors that reduce manual process overhead across business functions.  * Partner with Engineering and Data teams to ensure the internal platform is built to the same standards as product engineering: proper source control, code review, deployment pipelines, and documentation.  * Drive the team’s evolution from reactive IT support to proactive platform engineering, embedding engineering culture, practices, and accountability into how the function operates.  Drive AI and Productivity Tooling Adoption  * Own the strategy and governance for enterprise AI and productivity tools, including Claude, ChatGPT, and Microsoft Copilot, ensuring deployment aligns with the company's AI governance framework.  * Work with the CIO and functional leads to evaluate, pilot, and scale AI tools that deliver measurable productivity gains across the business.  * Ensure tooling decisions follow the principle of right tool for the right job, with clear boundaries between governed stack platforms and generative AI use cases.  * Track adoption, usage, and ROI across the AI and productivity portfolio, providing regular reporting to ETS leadership.   Run Collaboration and Communication Platforms  * Own the operational health and strategic direction of Slack and Microsoft 365 (including Teams, SharePoint, and OneDrive), ensuring these platforms are performant, well-governed, and fit for a hybrid, global workforce.  * Partner with IT and Security to enforce appropriate data controls, retention policies, and access governance across collaboration tools.  * Drive adoption and best-practice usage of collaboration platforms, working with internal communications and people teams where relevant.  Oversee End-User Technology and IT Operations  * Own the end-user compute function: laptops, desktops, mobile devices, and the service desk experience that supports Genius Sports employees globally.  * Maintain accountability for office networks, on-site infrastructure, and the reliability of workplace technology across Genius Sports locations.  * Ensure Active Directory and identity and access management (IAM) platforms are well-governed, current, and aligned to security policy, working closely with Cybersecurity on access controls and lifecycle management.  * Set the bar for device management standards, endpoint configuration, and IT onboarding and offboarding processes, ensuring consistency and security across the estate.  Lead and Develop the Team  * Build and lead a high-performing team of business systems, platform, tooling, and IT operations specialists, setting clear goals, developing capability, and holding the bar on quality.  * Create a team culture that balances operational reliability with a forward-looking mindset, ensuring the team is equally trusted to keep the lights on and to drive change.  * Partner closely with Data and Analytics and Cybersecurity to deliver joined-up technology outcomes for the business.   Shape the Enterprise Technology Roadmap  * Contribute to the ETS transformation roadmap, with particular ownership of rationalizing the tool estate, building the internal automation platform, and embedding engineering-grade practices into how the Business Technology team delivers.  * Lead the evaluation and selection of new tools and platforms, and where building is the right answer, own the architecture and delivery. Bring a commercially rigorous and technically grounded approach to build vs buy decisions, with the engineering credibility to execute either path.  * Provide ExCo-ready reporting on portfolio health, investment priorities, and risk across the business systems and productivity estate.   Governance, Risk, and Compliance  * Ensure business systems and productivity platforms meet audit, compliance, and data protection requirements, including SOX-relevant controls where applicable.  * Maintain clear documentation of system ownership, integration dependencies, and change management processes across the portfolio.  * Contribute to the ETS risk register, ensuring visibility of platform risks and remediation timelines at the right governance levels.  Qualifications   * Proven experience leading an enterprise technology or business systems function in a fast-moving, commercially driven organization, with direct accountability for both strategic platforms and operational IT delivery. You have an engineering background and have built things, not just managed vendors.  * Deep familiarity with the tools in scope: Salesforce, Atlassian, Zendesk, Microsoft 365, Slack, and AI productivity platforms. You do not need to have run all of them simultaneously, but you need to know how they fit together.  * A track record of translating business requirements into technology decisions, and technology investments into measurable business outcomes.  * Strong commercial instincts. You understand vendor dynamics, know how to negotiate, and do not let the portfolio sprawl.  * Experience managing cross-functional stakeholders at senior level, including Finance, HR, Sales, and Operations leaders who have strong opinions about the tools they use.  * Solid grounding in identity and access management, endpoint management, and IT operations governance, enough to set standards and hold a team accountable. Alongside this, hands-on experience with infrastructure-as-code (Terraform), CI/CD pipelines, cloud platforms (AWS or Azure), and API-layer integration. You can work in code, review it, and build teams that ship it.  * Clear, direct communicator who can present to ExCo and board audiences without jargon and with a sharp focus on business impact.  * Hands-on experience deploying AI and automation tooling in production, including agentic workflows, MCP Servers, or API-integrated AI platforms. A grounded view of where generative AI adds measurable value in an enterprise context, and the governance instincts to deploy it responsibly.  * Experience operating within a SOX-compliant or similarly governed environment is an advantage.    We enjoy an ‘office-first’ culture and maximize opportunities to collaborate, connect and learn together.

By giving our 6 million users a clear, open path to pay, save, and invest, we are evolving into the definitive destination for every financial need. You'll be joining the Consumer Growth team.

You will raise the quality bar across mobile and backend development: rigorous testing strategies, safe progressive rollouts, and proactive elimination of technical debt in a codebase that ships 2M+ daily payments. You'll champion simplicity and maintainability in services that other pods depend on. * Mentor and develop. You will provide technical guidance to junior and mid-level engineers in the Consumer Growth teams, helping them navigate cross-service dependencies, adopt sound event-driven patterns, and build a shared instinct for operational excellence. Expect challenges, collaboration, and the freedom to bring your ideas to life. Our tech stack includes (but it’s not limited to) PostgreSQL, Java, Spring Boot. We rely on AWS for our infrastructure, with microservices deployed on EC2/ECS, S3 for storage, AWS Lambda for serverless functions, and Kinesis and ElasticSearch for log streaming. You'll take ownership of your work from start to finish.

Does it sound like you? * Extensive experience: You have at least 5 years of related experience in back-end software engineering. You have a proven track record of working with microservices and cloud environments (AWS is a plus) in high-paced, mission-critical contexts. * Technical depth: You possess deep experience with Java and Spring Boot. You have a strong understanding of distributed systems and how to manage external dependencies (like banking protocols) effectively. * AI focus: You’re passionate about or have hands-on experience building GenAI-driven features, such as backend services using LLMs, orchestration frameworks like LangGraph, or AWS cloud services like Amazon Bedrock * Structured communication: You are able to communicate complex technical concepts clearly and convincingly. You excel at coordinating implementations with other teams and building trust with various stakeholders. * Impact mindset: You are focused on delivering software that meets evolving user needs. You are adaptable, avoid analysis paralysis, and "go the extra mile" to optimize systems beyond the initial requirements. * Passion and language skills: You are passionate about FinTech and fluent in English.
