The role
As a Senior Backend Software Engineer, you’ll work across the stack as we build our Arctic OS that integrates hardware feeds, varied data sources, and machine learning algorithms. You'll iterate quickly, shipping production code that powers systems operating where connectivity is sparse and failure isn't an option. This is a role for a solid generalist — someone who sees themselves as an enthusiastic dabbler, a jack of all trades, or a tinkerer at heart — content to learn new skills and move across projects as requirements evolve.
This role is full-time in-person atour HQ in the Cotswolds, just outside of Cirencester.
Core responsibilities
* Build and maintain data ingestion pipelines and processing systems
* Manage and develop cloud infrastructure
* Architect and optimise database systems
* Implement telemetry, logging, and monitoring solutions
* Design and implement REST APIs and web microservices
What we value
* 5+ years building production backend systems
* Proven experience with cloud platforms (we use AWS)
* Intellectual curiosity and the confidence to pick up new skills quickly
* Pride in reliability and operational quality, not just shipping features
* Comfort with ambiguity - we’re a young company and things change frequently
* Security engineering experience
* GIS or geospatial data handling
* Machine learning or data science background
* Time-series data and databases (e.g. InfluxDB, TimescaleDB)
* Data workflow orchestration (e.g. Airflow, Dagster)
* Ruby on Rails or Python
* Kubernetes and Helm Charts
* Infrastructure as Code (Pulumi, Terraform)
What we offer
* Competitive compensation
* Equity — meaningful options as an early employee at an early-stage company
* Real field exposure — travel to Arctic sites and Outposts when needed (genuinely, not as a gimmick)
* Mission-driven culture — focus on impact, not hours logged
* Small team, real ownership — what you build matters and ships
A note on who we want to hear from
We're building for one of the most demanding environments on Earth and we believe diverse teams build more resilient systems. We actively welcome applications from people who are underrepresented in engineering - whether that's by gender, ethnicity, disability, or background. If you're not sure you meet every requirement, apply anyway and tell us what excites you about the problem.
