Our Product & Engineering Team: Liberis is building the embedded finance platform that lets partners around the world offer innovative funding products to their small business customers. We're a growth-stage fintech with teams in London, Nottingham, Atlanta, Stockholm, Munich and Mumbai, and we’re building a global Product, Data & Engineering team that thrives on autonomy, ownership, and is focused on impact! Our teams solve real-world problems for small businesses, shaping products that unlock opportunity at scale. Engineering is going through an AI-first transformation, rethinking how teams are structured and how they ship. It's changing what a small team can do! We empower our teams to make decisions, move fast, and take full responsibility for the solutions they deliver. You’ll join a team where curiosity is encouraged and collaboration across Product, Data, Delivery and Engineering is the norm. The role: Joining our Cloud Platform team as a Lead DevEx Engineer, you will play a key role in improving how engineers build, ship and operate services across Liberis. This is a brand new role created to bridge the gap between application development and platform engineering - creating a more consistent, scalable developer experience as we continue to evolve our platform strategy. You will focus on building for engineers - creating and shaping the templates, standards and foundations used across services. Alongside this, you will have the opportunity to contribute to emerging platform initiatives, including work that supports AI enablement across the engineering organisation. This is a high-impact role with real scope to influence how engineering works at Liberis! What you'll get to do in the role: * Own and evolve the service template library for .NET, Node.js, and Python — covering project scaffolding, dependency management, containerisation, local dev setup, and production configuration. Templates are generated, not forked, so keeping them current and opinionated matters. * Build and maintain CI/CD pipeline templates in GitHub Actions and/or Azure DevOps, covering build, test, security scanning, and deployment — consistent across stacks and reusable across teams. * Define and ship observability standards: structured logging, distributed tracing, and alerting integrated into service templates so every new service is production-ready from day one. * Work hands-on with Datadog, incident.io, and/or GCP/Azure-native logging and monitoring tooling to build the platform-level observability layer teams plug into. * Contribute to our thinking on a potential Azure-to-GCP migration — helping assess what changes for developer tooling and service templates and building proof-of-concept work that informs the decision. * Partner with product engineers to understand where developer experience breaks down — slow pipelines, confusing templates, missing runbooks — and fix the root causes, not the symptoms. * Lead technical decisions on platform tooling: evaluate new tools, write ADRs, and drive adoption of improvements across multiple engineering teams. * Mentor engineers in the Cloud Platform team and act as a go-to resource for product engineers getting to grips with platform tooling. The interview process: * Screening call with Chess (Internal Recruiter) (30 mins) * Video interview with the Hiring Manager (45 mins) * In person code pairing interview with a member of Engineering team (1 hour) * Video interview with the wider Liberis team (1 hour) What we think you'll need: * Proficient in at least one of .NET (C#), Node.js and Python — able to build, configure, and template production-grade services in each. * Strong GCP experience (Azure experience is nice to have) * Hands-on experience designing reusable CI/CD pipeline templates — GitHub Actions or Azure DevOps — consistent across stacks and teams. * Comfortable with containerisation (Docker) and deployment on Kubernetes or Cloud Run. * Observability experience with at least one of: Datadog, incident.io, or cloud-native logging and monitoring (GCP Cloud Operations or Azure Monitor). * Infrastructure-as-code with Terraform. * A proven track record of driving adoption — building things engineers use, writing docs that get read. Career development is really important to us here at Liberis, with progression opportunities for both individual contributors and people managers. You can have a look through our Engineering Career Framework via this link Our hybrid approach Working together in person helps us move faster, collaborate better, and build a great Liberis culture. Our hybrid working policy requires team members to be in the office at least 3 days a week. At Liberis, we embrace flexibility as a core part of our culture, while also valuing the importance of the time our teams spend together in the office. #LI-FC1

LEAD SOFTWARE ENGINEER - DEVELOPER EXPERIENCE (DEVEX) IN SHORT At On, we believe technology should move as fast as a runner. We are building the foundation that allows our engineering organization to scale, innovate, and deliver value without friction. We are looking for a Lead Software Engineer to join the Developer Experience (DevEx) team. In this hands-on role, you will build the platform that empowers dozens of technology teams to build, ship, and operate services effortlessly. You will be involved in architecting and building our "Golden Path," ensuring that speed, safety, and reliability are baked into every developer's workflow. YOUR MISSION * Help Engineer the Golden Path: Design and implement highly automated CI/CD pipelines (GitHub Actions) and common templating (Typescript/Node) systems that allow a developer to go from "idea" to "production-ready service" in minutes. * GraphQL Infrastructure: Act as a core contributor to our central Apollo GraphQL API Gateway. You will help manage the supergraph composition, runtime stability, and schema governance standards to ensure a consistent contract for all consumers. * Help to Build the Internal Developer Platform (IDP): Help develop our Cloud Abstraction Layer and Developer Portal. This includes building self-service tools, CLIs, and service catalogs that reduce cognitive load for engineers. * SRE & Observability: Integrate "secure-by-default" practices and robust observability into the platform. You’ll build dashboards (NewRelic) and monitoring patterns that provide teams with deep insights into their service health. * Technical Excellence & Advocacy: Write high-quality documentation, help with code reviews and advocate for DevEx best practices across the organization. * Friction Reduction: Actively hunt for bottlenecks in the software development lifecycle. Whether it's a slow build or a complex deployment process, you'll be involved in fixing it. YOUR TECHNICAL STORY * Product Thinking: You treat internal developers as your customers. You listen to their pain points and iterate on the platform based on real-world feedback. * Infrastructure as Code: You are comfortable with Terraform and Kubernetes (GCP experience is a plus), treating infrastructure with the same rigor as application code. * Automation Mindset: You are passionate about CI/CD (GitHub Actions) and building developer tooling (CLIs, SDKs, or Portals). * AI-Augmented Engineering Workflows: You leverage (or at least have an active interest in) the latest agentic coding tools to 10x your productivity, blending deep technical principles with AI-assisted workflows. As a power user of AI, you orchestrate complex builds and bypass boilerplate to deliver robust, scalable code at pace, ensuring our TypeScript/Node.js environment remains lean and efficient (experience in other tech stacks will be considered). * Architectural API Design: Experience in crafting robust API contracts with a focus on GraphQL Federation; familiarity with the Apollo tech stack is highly regarded. * Data-Driven: You understand DORA metrics and DevEx signals, using them to measure the success of the tools you build. WHAT SUCCESS LOOKS LIKE * Velocity: A measurable reduction in lead time for new services reaching production. * Autonomy: Product teams can provision infrastructure and deploy APIs independently using your self-service tools. * Stability: High adoption of standardised "Golden Path" templates, leading to fewer production incidents and faster MTTR. * Satisfaction: High internal Developer Satisfaction (DevEx) scores and positive feedback on the tooling you maintain. * Team Spirit: You thrive in a high-performing "sports team" culture, contributing to the power of the whole through consistent teamwork and earned leadership. MEET THE TEAM The Developer Experience team serves as the bridge between infrastructure and product. We don't just measure "uptime"; we measure "time to value." As a Staff Engineer on this team, you will be at the heart of our engineering culture, defining the standard for how software is built and delivered at On.
