Senior Engineer

About the role

Join a small but rapidly growing engineering team, working alongside founders who have scaled companies before. As a Senior Engineer you will shape the architecture, the stack, and the standards that future engineers inherit.

Key responsibilities

• Own features end‑to‑end, from data model to the customer‑facing interface.
• Design systems that process large volumes of AI‑search interactions reliably.
• Ship weekly and iterate on real usage, not quarterly plans.
• Make technical decisions that shape product direction, not just implement specs.
• Help hire and mentor as the team grows.

Required profile

• Several years shipping production software, comfortable across the full stack, with experience scaling backend and distributed systems or building production‑grade agentic systems.
• Strong, loosely held opinions on system design – argue your corner, then follow the evidence.
• Comfortable with ambiguity and able to turn vague problems into shipped features.
• Take ownership beyond immediate remit.
• Care about craft: testing, readability, reliability and services that outlive their first version.
• Motivated to build something that changes how marketing teams work and to have a real stake in the outcome.

What we offer

• Competitive salary (DOE) with early‑stage equity.
• 25 days holiday plus bank holidays.
• Leading parental and childcare policies.
• Office‑based work five days a week near London Bridge.
