Staff Product Engineer
Staff Product Engineer
London | Hybrid | Full-time
Salary: Up to £125,000
We’re partnering with a high-growth, AI-native consumer technology start-up that’s tackling a large, complex and highly visible everyday problem at national scale.
They’re looking for a Staff Product Engineer to operate at the intersection of product, engineering and systems design, owning a small number of high-impact initiatives that materially change how customers experience the product and how the platform scales.
As a Staff Product Engineer, you’ll lead complex, cross-cutting initiatives from problem definition through to production, working closely with product, operations and leadership.
You’ll focus on turning ambiguous, real-world problems into simple, reliable systems, shipping incrementally and measuring impact continuously. You’ll also help define the technical patterns, primitives and “paved roads” that enable a small, fast-moving engineering team to scale effectively. This role reports directly into senior technical leadership and has clear visibility at exec level.
Key Responsibilities
- Own and deliver a small number of high-leverage, business-critical initiatives each year
- Translate complex, fuzzy problems into clear technical and product plans
- Design and ship end-to-end solutions in small, frequent production releases
- Act as a domain owner across one or more core areas (e.g. frontend, workflows, infrastructure, data or AI-driven systems)
- Define reusable patterns, libraries and workflows that improve reliability, speed and clarity across teams
- Mentor and unblock senior and emerging engineers, raising the technical bar across the organisation
- Produce clear written documentation to align engineering, product and operations
Tech Environment
- Full-stack TypeScript, React, Postgres
- Modern cloud infrastructure (AWS, Terraform)
- Strong observability and monitoring practices
- Data platforms and analytics tooling
- AI-powered systems working with complex, unstructured real-world data
(Exact tooling is less important than strong engineering judgement and product thinking.)
What They’re Looking For
- Strong experience operating at Staff / Principal / Lead Engineer level
- Proven ability to lead cross-team, ambiguous initiatives that move core metrics
- Deep product mindset alongside excellent software engineering fundamentals
- Comfort designing systems, workflows and failure modes — not just features
- Enjoys mentoring, improving how teams work, and raising overall engineering effectiveness
- Happy staying hands-on in code while influencing technical direction
- Prefers smaller, high-agency teams over large, process-heavy environments
Benefits
- Competitive salary + meaningful equity
- 33 days holiday (including bank holidays)
- Health & dental cash plans + EAP
- Travel benefits (cycle to work, season ticket loans)
- High-quality equipment and learning budget
- Well-supported, collaborative office environment
