Full-Stack Engineer - Full-time position
About the role
Experienced full-stack engineer to join HyLight's Platform Team, building internal tools, ground station software, and cross-team automations to support flight operations and data-driven insights.
Responsibilities
- Ship internal applications the team relies on every day — mission planning, fleet & inventory tracking, post-flight review, regulatory dashboards, CRM-adjacent tooling.
- Own the business model in code. Embed yourself with the teams you build for, learn how the company actually operates, and translate that into clean data models and the right abstractions.
- Kill manual workflows. Identify repetitive, error-prone steps slowing the company down — compliance paperwork, team hand-offs, status updates — and replace them with software.
- Integrate the tools the team already uses (Notion, Slack, GitHub, OnShape) so data flows automatically and a single source of truth exists across the company.
- Tackle hard, domain-specific problems: help operations turn a vast set of criteria — weather, airspace, regulation, fleet availability, mission objectives — into a concrete flight schedule.
- Contribute to the ground station — telemetry dashboards, sensor feeds, and pilot-facing tools — working closely with the embedded team on clean contracts between the aircraft and the ground.
- Design and maintain the APIs and services supporting frontend applications and integrations.
- Build automations and AI-powered tools that give the team real leverage.
- Own what’s already running: fix bugs, refactor when it earns it, monitor reliability, and make sure what the team depends on every day keeps working.
Qualifications
- Bachelor/Master in Computer Science, Software Engineering, or equivalent practical experience.
- A few years of experience building and shipping full-stack web applications — we care about what you’ve built, not where you studied.
- Track record of end-to-end ownership: you’ve shipped things, dealt with production messiness, and kept going.
- Genuine interest in building tools that people inside a company use and depend on every day.

About HyLight
Small unmanned hydrogen airships for long range monitoring
HyLight builds and operates autonomous airships for long range monitoring. We focus on detecting methane leaks on pipelines and defects on power lines. Our innovation, the HyLighter, is a crossover between drone and airship technology. Like a drone, it is easily controllable and transportable. And, like an airship, it is extremely energy-efficient, enabling it to fly for up to 10 hours at slow speed (22mph) for optimal data collection which represents a range of 220miles. Today, energy infrastructure operators struggle with conducting inspections that are simultaneously: massive and precise. HyLight offers a solution to precisely detect issues on the infrastructure at an industrial scale, and all of this without emitting GHGs. We are 3 co-founders experienced in hardware and energy companies with Masters in Mechanical Engineering, Computer Science and Business from the best Engineering and Business School in France. We have developed 5 different flying aircrafts and signed 5 pilots programs with major energy infrastructure operators. We also have LOIs worth over $3.5M.
