About the Role
We’re looking for a senior product engineer to operate as a technical leader within Caribou — someone who can own major parts of the product and help shape both what we build and how we build it.
This is not a typical engineering role. You’ll act as a de facto technical co-pilot to the founders: driving architecture, shaping product direction, and translating ambiguous business problems into high-quality, scalable solutions.
You should be a highly experienced full-stack engineer with strong product instincts, a track record of building from 0→1, and the ability to operate with very high autonomy. You’re comfortable working solo when needed — across engineering, product, and design — and care deeply about craft and user experience.
With the rapid evolution of AI and LLMs, you’re expected to be at the frontier: leveraging new tools, paradigms, and techniques to move faster and build better products.
You’ll work directly with the founders and operate at the intersection of engineering, product, AI, and design — turning complex, ambiguous problems into elegant, customer-facing solutions.
You Will Be Doing…
- Leading full-stack development of core product areas from problem definition through to production and iteration
- Acting as a technical owner for major parts of the product, making key architecture and infrastructure decisions
- Driving product discovery: speaking to users, mapping workflows, identifying opportunities, and shaping what gets built
- Leveraging AI/LLMs pragmatically — to accelerate development, power product features, and rethink complex workflows (especially in tax)
- Collaborating closely with founders and domain experts to deeply understand user problems and translate them into product improvements
- Raising the bar for engineering quality: maintainable code, strong abstractions, and scalable systems
- Improving engineering velocity and processes in a fast-moving, early-stage environment
Requirements
- 8–12+ years of experience as a full-stack or product-focused engineer, ideally in high-growth or early-stage environments
- Proven track record of building and shipping products from 0→1, owning both product and technical decisions
- Strong technical depth across modern frontend (React/TypeScript or similar) and backend systems (Go, Node, Python, or similar)
- Experience leading architecture and making high-impact technical decisions in ambiguous environments
- Strong product intuition — able to drive discovery, user interviews, and feature shaping, not just execution
- Deep interest in AI/LLMs, with hands‑on experience integrating or applying them in real‑world systems
- Excellent communication skills, with the ability to explain trade‑offs and influence product direction
- Highly self‑sufficient, with strong judgment on when to collaborate vs. move independently
- Experience in early‑stage startups or similarly high‑autonomy roles
Perks & Benefits (for UK-based full-time employees)
- Competitive salary
- Significant equity — we want this to feel like a founder‑level opportunity
- 100% book subsidy
- Pension
- Health insurance
- Custom WFH equipment setup
