Wedo has partnered with a Tech4Good Series B start-up who are building technology that impacts tens of millions of people every year. Our client is a B Corp, featured as one of the fastest-growing companies in the UK, and they’re now looking for a Staff Software Engineer who can own Go service development for their core platform, while having a wider impact by owning architecture patterns, setting standards, influencing strategy, and driving wider Go adoption.

Their previous services were written in Node / Next.js, which hit performance limits. They put together a Go proof of concept which showed they could 10x performance, so all new services and feature development are now being built in Golang. They have 2 Go Engineers in the business and are hiring 2 more. This is an IC role and suitable for anyone who’s already a Senior looking to step up, or someone already operating at Principal or Staff level.

• Design and create automated tests across the full testing pyramid
• Improve system performance, data modelling, reliability and UX
• Shape architectural decisions and unblock complex problems
• Mentor engineers adopting Go and level up engineering standards
• Champion product-thinking, always tying decisions back to user need

What You’ll Bring

• Commercial experience building Go services in production in at least 2 different companies
• Willingness to unblock yourself and work with TypeScript / React for ~10% of the work, with appetite to learn on the job
• PostgreSQL expertise
• Automated testing mindset (ideally TDD)
• Solid grounding in design patterns
• Cloud deployment experience (Kubernetes preferred)
• Kafka, Debezium or broader event-driven systems knowledge
• AWS experience

You’ll Thrive Here If You Are…

• Fuelled by purpose, not perks
• Excited by scale, ambiguity, and building from the ground up
• Curious, collaborative, and generous with knowledge
• Someone who gives and receives feedback well
• Able to influence direction, not just follow it
• Product-thinking, pragmatic, and comfortable making trade-offs

You don’t need to tick every box. If the mission resonates, you should apply.
