Job Description

About the Company

We are partnering with a fast-growing, AI-first company to build enterprise-grade intelligent systems that are already live in real-world, high-impact environments.

About the Role

This role is focused on execution and ownership: taking complex problems and turning them into reliable, scalable production systems. As a Senior Software Engineer, you will work in a high-performing, self-organizing team at the intersection of software engineering and applied AI. You will be hands-on, close to the code, and accountable for shipping quality work in a fast-moving environment. This is not a research position. It’s about building, operating, and improving real systems that matter.

Responsibilities

Design, build, and maintain production-grade full-stack systems with a strong focus on reliability and performance.

Contribute to architectural decisions and technical direction within the team.

Collaborate closely with product managers, designers, and other engineers to deliver end-to-end solutions.

Write high-quality, maintainable code and raise the engineering bar through reviews and best practices.

Make pragmatic trade-offs, balancing speed, quality, and long-term sustainability.

Qualifications

Strong track record of high performance in fast-paced environments.

Comfort working in self-organizing teams with changing priorities.

Clear, effective communication and a collaborative mindset.

A strong sense of ownership and accountability for outcomes.

Required Skills

Strong fundamentals and adaptability are key.

Profile split: ~80% Software Engineering / ~20% AI.

Solid software engineering fundamentals (system design, code quality, scalability).

Ability to adapt quickly to different full-stack environments.

Hands-on production experience with TypeScript and React.

Skills

Practical exposure to Large Models in applied settings.

Basic understanding of agent-based architectures and their core components.

Good prioritization skills when integrating AI features into production systems.

Pay range and compensation package

Hybrid role: London-based, on-site 3 days per week.

Initial onboarding will take place in person in San Francisco, working closely with the core team.
