Staff Software Engineer

Staff Software Engineer Golang & TypeScript/React London (Hybrid)

Salary: 100,000 - 115,000 (+/- 10% DOE)

We're working with an early-stage product company building a platform that sits at the intersection of data, automation, and decision-making.

The team is tackling a complex problem around how organisations operate and optimise processes at scale, using modern software and AI to improve speed, accuracy, and outcomes.

It's a product-led environment with high ownership, where engineering plays a central role in shaping both the system and how it's used.

The Opportunity

• Play a key role in shaping and delivering their platform
• Lead technical decision-making across backend systems and architecture
• Work closely with customers to influence product direction and feature design
• Operate in a highly autonomous, product-driven environment
• Build scalable, high-performance systems used by modern B2B organisations

What You'll Be Doing

• Contributing across backend and web systems (Golang, Typescript, AWS)
• Designing and scaling system architecture for new and existing features
• Leading projects and guiding engineering direction
• Defining and implementing REST APIs for internal and external use
• Driving innovation across backend technologies and engineering practices
• Collaborating directly with customers to shape product outcomes

The ideal candidate is someone who takes real ownership, not just writing code but shaping the problem and outcome. They're naturally product minded, curious about users, and comfortable making decisions in environments with high autonomy and little structure.

They communicate clearly, influence others without relying on title, and enjoy working closely with a team to build something meaningful. They thrive in fast moving settings, balance speed with quality, and are motivated by being surrounded by smart people working on genuinely challenging problems.

What We're Looking For

• Senior/Staff-level engineering experience (5+ years IC experience)
• Proven experience leading teams or complex technical projects
• Strong backend expertise with Golang and Typescript
• Experience building systems in modern cloud environments (AWS/GCP)
• Strong understanding of scalable architecture and system design
• Ability to influence, mentor and inspire engineers
• Experience working in fast-paced, high-feedback product environments

SR2 and our client are committed to building diverse teams. Applications are encouraged from all backgrounds, regardless of whether every requirement is met.
