🧭 The mission

OET is building open-source, high-performance tools for energy and grid planning - software that helps system operators, regulators, policymakers and researchers plan faster, more transparent transitions to clean energy. To learn more about OET and our team, you can visit our website.

🎯 The role

We’re looking for a Senior Geospatial Frontend Engineer to own the interactive mapping experience in an enterprise-grade open-source product. You’ll build fast, intuitive geospatial workflows for editing, styling, and exploring large network and time-series datasets, turning complex energy models into something users can trust and operate at speed. This is a hands-on, senior role: you will ship high-quality features, influence architecture, and raise the bar for frontend craft across the team.

This role is for people who enjoy building products more than building technology for its own sake. You’ll lead with a strong UX mindset, and you’ll make pragmatic decisions that improve user outcomes, not just code quality.

Our Head of Software Engineering (aka your future Manager): Sid Krishna

🛠️ Your Key Responsibilities

Own the mapping experience as a product-quality system: build and evolve a high-performance geospatial UI where interaction design, performance, and reliability are treated as first-class concerns.
Build “pro-grade” geospatial editing workflows: create tools for drawing and editing points/lines/polygons, including selection states, snapping, validation rules, undo/redo, and exportable artifacts.
Deliver a styling/symbology experience users trust: implement a layer/style editor that supports portable styles, sensible defaults, and powerful “color/size by attribute” workflows — without overwhelming users.
Make large datasets feel smooth: profile performance, manage memory responsibly, and use the right techniques (virtualization, background computation, incremental updates) so everything stays responsive.
Design robust state and interaction architecture: build a maintainable foundation for complex UI state, event handling, and tool modes — the kind that doesn’t collapse when features scale.
Collaborate in a “product trio” style: work closely with product and design, and partner with domain experts to translate real workflows into interfaces that users love and trust.
Ensure technical excellence: write clean, testable TypeScript, build reusable UI components, and help establish patterns that keep velocity high without sacrificing stability.
Communicate clearly and proactively in remote work: tailor communication for different audiences, document decisions, and keep momentum without needing constant meetings.
Bring your own lessons learned: apply what you’ve learned from past product wins and failures to help OET level up.

✅ You’ll Be a Great Fit If You Are/Have...

6+ years building modern frontend applications with React + TypeScript (or equivalent senior-level experience)
Strong product engineering instincts: you can turn messy requirements into clean UX and reliable code with a “ship it, own it” mentality: you care about outcomes, polish, and real users.
Deep familiarity with web mapping (MapLibre GL / Mapbox GL style ecosystems), including layers/sources, style expressions, and interactive performance constraints.
Hands-on experience building geospatial editing tools with maplibre-gl-terradraw and Turf.js (drawing, vertex manipulation, snapping, selection states, validation).
Proven ability to ship complex features end-to-end: design tradeoffs, implementation, testing, and iteration with real users.
Excellent written communication and comfort working asynchronously in a fully remote team.

⭐ Big plus:

Experience with customisable Dashboards
AI driven UX/UI development and a good feeling for user-friendly designs
Data visualization experience (time series, scenario comparisons, brush/zoom, legend interactions).
Electron experience (desktop constraints, IPC, file system integration).
Domain familiarity: energy systems, grids, PyPSA, OR/optimization workflows, or scientific/engineering software UX.
Proven track record of meaningful open-source contributions

No university degree required - your experience, judgment, communication, and craft matter most. However, a degree may be a bonus.

✨ What We Offer

A flexible, fully-remote work environment where you’re trusted to work very autonomously. Zero micro-management, as that goes against our culture.
The opportunity to support hardworking, passionate, busy leaders who value and respect your contributions, and are working to create positive societal change in the energy sector.
A culture that values transparency, empathy, trust, humility, diversity, collaboration, and recognition.
We have an open-door policy, and value reciprocal feedback. You’ll always know where you stand, and always have the ability to have your voice heard, simply by reaching out.
