About Kew Reach

A better future for people and planet, made possible through the power of a thriving and resilient natural world. Launched in 2024, Kew Reach is a joint venture with the Royal Botanic Gardens Kew, set up to deliver nature-based solutions to restore ecosystems in any setting. We accelerate nature-positive action at scale, grounded in scientific expertise, shaped by creative thinking, and sustained through collaboration.

What We Do

We offer an end-to-end service guided by the Kew Method, spanning baseline assessment, climate-informed design and delivery, species sourcing, long-term monitoring and capacity building, ensuring every project is credible, resilient and delivers measurable nature gain.

This spans three Labs: the City Lab, bringing climate-resilient planting and green infrastructure into city and development environments; the Restoration Lab, turning degraded land into resilient, biodiverse ecosystems; and the Infrastructure Lab, delivering nature-based solutions for major capital projects.

Introducing Palette

Our platform, Palette, brings that same scientific confidence to decisions about planting, biodiversity and habitat. Built around our core climate-resilient tree species-selection tools, we're expanding its capabilities to cover pollinator and habitat analysis, combined biodiversity planning, and tools designed for local-authority use.

The role

You will be the engineer who owns the health of the platform and its growth: its security posture, its reliability and deployment pipeline, the day-to-day usability of the application, and the new client-facing capabilities we build in the future. As those capabilities grow, you'll mature the platform from a single application into a suite of tools that you manage centrally. You'll work alongside our Senior Data Scientist and the CEO.

This is a founding platform-engineer role: broad, high-ownership, and, for now, the sole engineer on the platform side. You'll turn client needs and our domain expertise into features, not just keep the lights on. It suits someone who wants the autonomy and scope of an early hire and is comfortable being the person the platform depends on.

The immediate priority is honest: the migration to our current AWS architecture was largely AI-assisted. The architecture is sound and well-documented, but there is a known, already-scoped list of hardening, reliability and polish work to reach a confident commercial launch.

What you'll own

  • Product & platform evolution: Grow the platform beyond its first study - turning client needs and our scientific domain expertise into features that help users understand their sites and act on that understanding.
  • Security & compliance: Take our launch security checklist from "mostly coded" to "verified and deployed” WAF rollout, harden the authentication and session model, drive secret hygiene, and support UK data-residency requirements.
  • Reliability & operations: Own the AWS infrastructure and improve observability, own the deploy pipeline and make releases boring.
  • Usability & frontend quality: Improve the end-user experience and strengthen input validation, error handling and rate limiting across the API.
  • Engineering practice: Uphold our test discipline and keep the architecture documented.

Where we are today

You'd be walking into a platform that is already well past prototype: Live product with ~320 species scored across 12 UK regions. Stack includes React, Tailwind, Express, TypeScript, PostgreSQL, and AWS services.

Known open work includes deploying the WAF, adding CloudFront, finishing security headers, hardening sessions, and enabling CloudTrail/GuardDuty/Config.

Essential experience includes strong TypeScript skills, solid AWS experience, demonstrable application and cloud security know-how, experience running production web services, and relational databases knowledge.

Desirable experience includes familiarity with tRPC, PostGIS, multi-tenant SaaS, and frontend accessibility and performance.

This is not a data-science or modelling role - your focus is the platform and its product: security, stability, usability, and the new capabilities we grow on top.
