Senior Software Engineer

Graphcore

ABOUT THE JOB Help prove the ML software stack that future AI systems will depend on. Graphcore is expanding the software systems behind AI compute at datacenter scale. This role focuses on validating a complex machine learning stack before it reaches customers and hardware.You will build the test infrastructure, automation and tooling that engineers trust every day. Your work will help raise reliability, performance and maintainability across frameworks, simulators, emulators and future hardware. You will shape test architecture across large codebases, CI pipelines and representative ML workloads. You will use strong software engineering judgement to turn complex technical goals into scalable validation systems. This is a role for someone who enjoys depth, ownership and useful engineering. You will make quality easier, faster and more visible for teams building at the edge of AI compute. THE TEAM AND CULTURE The ML QA team sits where Graphcore’s software components come together. Engineers work across unit tests, integration tests, full model runs, subgraph validation and benchmarking. Work is organised through focused squads with clear ownership. People are expected to step up, speak openly and improve how the team builds, tests and learns. Decisions are grounded in evidence from code, data and system behaviour. The team works closely with software teams to identify gaps, improve tooling and move priorities forward quickly. WHAT WE’RE LOOKING FOR · Strong software design skills, with experience building maintainable systems across large codebases. · Production Python experience, including testable, reliable code used by other engineers. · Experience with CI/CD, automated testing and Linux based development workflows. · Familiarity with C or C++, with confidence reading and debugging low level code. · Understanding of ML frameworks, workloads or model execution beyond simple API usage. · Ability to mentor engineers, improve practices and take ownership of complex technical problems. BENEFITS · Unlimited annual leave · Up to 5% matched pension · Phantom equity – share in Graphcore’s success · True flexibility in how and where you work · Office spaces designed for collaboration · Free food and an on-site barista · Health cash plan · Income protection · Life assurance · Along with other benefits you can choose from (private medical insurance, dental plan etc) We welcome people from all backgrounds and experiences and are committed to building an inclusive environment where everyone can do their best work. We’re an equal opportunity employer and recognise that everyone brings different strengths and perspectives. If you need any adjustments during the interview process, just let us know - we’re happy to support you.

Redgate

AT A GLANCE Location: Cambridge In-office expectation: Once every two weeks Employment type: Permanent Salary: £55,000-£80,000 This role will be a mid or senior level engineer dependant on experience WHY THIS ROLE EXISTS Redgate's Foundry is our innovation incubator, the team scanning the horizon for Redgate's next big opportunity. This role exists because that kind of work needs engineers who are genuinely excited by discovery: people who can form a hypothesis, test it fast, and make a clear-eyed call on whether to push forward or change course. Most ideas won't become products. That's by design. Each experiment sharpens our thinking and improves the odds of finding the one that will. If you're motivated by that kind of challenge, where the destination isn't fixed and the work is never the same twice, this is the role for you. ABOUT REDGATE Redgate brings together people who want to do their best work in an environment built on trust, accountability, and collaboration. We build solutions that help data professionals securely manage the data and databases that their organisations depend on, a space that's only becoming more critical as systems scale, data regulations increase, and AI adoption accelerates. AI AT REDGATE By 2028, Redgate will operate as an expert plus agent company: domain experts amplified by AI, delivering customer value at a pace our peers can't match. AI handles the heavy lifting, and our people control the judgement. Everyone at Redgate works with Claude, giving you access to the best AI tools from day one. WHY JOIN OUR ENGINEERING TEAM? * You'll work in a team that cares about collaboration, craft and quality, not just in how we build, but in choosing what to build, finding the shortest path to the questions that matter most. * There’s real scope to grow your skills and impact, with clear pathways and support. * We value sustainable delivery, good ways of working and time to improve how we build. ABOUT THE ROLE The Foundry operates differently to the rest of Redgate's product teams. You won't be handed a roadmap. Instead, you'll work across the full arc of innovation — from horizon-scanning and ideation through to early-stage research, rapid prototyping, and working directly with customers to validate what you're building. You'll be part of a small cross-functional team (a Tech Lead plus four to six Software and Machine Learning Engineers), and you'll regularly run projects in parallel: contributing to ongoing experiments while also exploring entirely new directions. The tech stack is deliberately varied, the right tool for the job, not a fixed list, spanning C#, TypeScript, Python, and more across desktop, web, API, database, and ML development. What makes this role different: * You'll work on problems where there is no established answer and you'll have the autonomy to explore them seriously. * Your work sits at the intersection of software engineering, customer insight, and product thinking; it's rare to find all three in one role. * You'll use and help shape how Redgate adopts agentic coding and AI development tools, not as an afterthought, but as a core part of how the team works. * The scope is genuinely broad: a typical day could see you balancing technical prototypes, customer interviews, and competitor teardowns. WHAT MAKES YOU A GREAT FIT * Proven experience using AI coding tools. You've used them extensively, understand their limitations, and have developed ways to work around them productively and safely. * Strong software design and coding skills across modern languages, particularly C#, TypeScript, or Python, enough to guide and review AI-generated code with confidence. * Hands-on experience building agentic systems using frameworks such as LangGraph, Microsoft Agentic Framework, or MCP, with a solid understanding of LLM capabilities and risks. * Experience designing and running experiments to validate ideas quickly, using technical prototypes, customer feedback, and lean startup principles to test assumptions and make clear decisions. * Comfortable engaging directly with customers and stakeholders: running interviews, demos, and concierge-style validation processes, and communicating findings clearly to both technical and non-technical audiences. * A product mindset; you think in terms of user value, outcomes, and market fit, not just features or technical delivery. WHAT WE OFFER * · Salary range: £55,000-£80,000 * · Hybrid working: home and Cambridge office * · Monthly wellbeing allowance and generous paid time off * · Genuine investment in learning, development, and career progression * · Private health insurance WHAT HAPPENS NEXT Your application will be reviewed by a person, we don't use AI or automated tools to assess applications. Every profile is read by one of our Talent Partners. You'll hear back within a few days, whether it's a next step or a no, we aim to respond promptly so you're not left wondering. Our interview process is straightforward and consistent, you'll find more detail on our typical hiring process below, so you know what's coming and why. BELONGING AT REDGATE We believe that people do their best work in an environment built on respect, fairness, and trust and that diverse perspectives lead to better outcomes. Redgate is an equal opportunity employer, and we make hiring decisions based on skill, potential, and alignment with our values.
