Early-Stage AI "Software Factory" Disruptor

Our partner is a high-growth, VC-backed startup tackling a massive societal challenge: the digital transformation of physical industries like energy, manufacturing, and logistics. While most software ignores these "real-world" sectors, this team is building an AI-powered Software Factory to deploy bespoke digital tools that fix fragile legacy systems.

Backed by top-tier investors like Notion Capital and Hoxton Ventures, they’ve seen explosive revenue growth since 2023 and are now scaling an "all-star" early engineering team. This is an opportunity to join a mission-driven company where your code directly impacts the stability of global supply chains and economies.

What you’ll do

We are looking for a Lead Software Engineer who will lead a team of 3-6 talented engineers while spending more than half your time doing deeply technical work. You will be responsible for building high-performing teams, shaping technical direction, and ensuring delivery of impactful projects. You will be part of an all-star early team, building the future of software.

• Lead and develop a team of 3-6 engineers, providing coaching, feedback, and career growth opportunities.
• Own delivery of technically complex, high-impact projects, ensuring quality and scalability while balancing trade-offs under pressure.
• Contribute to architecture and systems design across multiple product areas, bringing clarity in ambiguous situations.
• Write and ship high-quality, efficient, and reliable code that is extendible, scalable, and observable. You know how to move fast without breaking things and you know how to keep the right balance between experimentation and shipping.
• Take ideas from experimentation to shipping. You intuitively know what a great product looks like.
• Build and help foster an engineering culture that encourages innovation and high-quality code standards, while shipping fast.
• Collaborate closely with other teams to build world-class software.
• Work closely with Product to help define the roadmap and set objectives.

What you’ll bring

We are looking for a leader who thrives in the "ambiguous" phase of a startup and has a "buck stops here" attitude.

• At least 3 years of experience leading and hiring engineering teams, with a track record of working in complex, large codebases.
• Proficiency in modern typed Python, Go, or modern Frontend development, along with experience in Docker, PostgreSQL, or DSL/Compilers.
• Professional or enthusiastic personal experience with LLMs and their ecosystems (e.g., Langchain, RAG, or observability tooling).
• You are a "creative experimentalist" who can balance the need for speed with long-term engineering maintenance.
• A commitment to building diverse teams; notably, candidates with career breaks or CV gaps are explicitly encouraged to apply.

What you’ll get

• Competitive salary and a share option plan.
• Private healthcare (including family cover and pre-existing conditions) and access to on-site gym/fitness classes.
• An excellent pension scheme, fixed at 7.5%.
• 25 days of annual leave plus public holidays.
• A hybrid working model (typically 2 days per fortnight in their London office), with negotiable schedules.
