Tech Lead Full-Stack Engineer (f/m/x)
Skills
About the role
As the Tech Lead for the backend, frontend, mobile and fullstack software engineers, you will own and shape the architecture of the underlying services as well as their technical roadmap for the services that together create Treeline, our application that helps predict and prevent wildfires, storm events and generally power and train outages due to vegetation, weather and climate.
Technically, that means rendering and querying large volumes of geospatial data efficiently in both browser, mobile and backend, handling complex and custom business logic, writing the services that make that fast, and building integrations for the growing number of third-party consumers of our services.
We are a team of five engineers today, actively growing, embedded in a cross-functional group of product managers, UX/UI designers, data, DevOps, ML, and geospatial engineering experts. You will not be the only person responsible for any system you touch and we’re a friendly bunch.
Your challenge
Lead, support and coordinate the team that builds Treeline while still being around 60% hands-on
Architect, build and extend features end-to-end that handle large volumes of geospatial data, with attention to UX and design
Design and build well-designed, performant API endpoints and backend services used by partners and customers
Coordinate tightly with other functions in cross-functional temporary squads
Shape and influence how your team works and how we work together in a greater context
Stack:
Frontend: React, TypeScript
Backend: NestJS, TypeORM
Mobile: React Native
Database: PostgreSQL (including geospatial workloads, PostGIS and OGC)
Infrastructure & CI/CD: AWS, GitLab
Your profile
Must have
First experience as a techlead, knowing that the team and product takes priority over your own hands-on work, always
Strong Backend experience with NestJS, Express, or Node.js
High level of TypeScript, React in production (Vue or Preact also fine - we care that you know a component model well, not which one)
Familiarity with mobile development, especially React Native
You've worked in a codebase with CI/CD and code review, and can find your way around a system you didn't build
You've used AI-assisted coding in your actual day-to-day, not just tried it once
Nice to have
Spec-driven or test-driven development, agentic or otherwise
Web-based geospatial / GIS work
An eye for design and UX - enough to make small design calls without needing a mockup for everything
Your Benefits
The opportunity to create a product that can improve business processes and lives across the globe.
Flexible working hours and hybrid work model - we trust our employees to get their work done while maintaining a healthy work-life balance.
We empower employees to drive their own career development, take initiative and have the freedom to be creative and bold.
Not an overtime culture - we take care that overtime is done only as a necessity and always offset with time off and rest.
A collaborative and learning environment - frequent internal workshops, knowledge sharing sessions, journal clubs and hackathons.
Office located in the centre of Berlin Kreuzberg with free fruit, nuts and drinks.
Potential to participate in the employee stock option program.
Urban Sports membership and BVG subsidy, corporate pension program.
A diverse and vibrant international environment of 30+ different nationalities.
