HyLight is recruiting engineers and scientists in Paris to build hydrogen‑powered airships that inspect pipelines, power lines, and railways over long distances. The company does not advertise broad role buckets; it hires against specific technical functions, and teams align with the disciplines needed to keep an unmanned aircraft flying for hours while carrying sensors and AI payloads. That means HyLight looks for engineers who can blend mechanical, software, and aerospace skills without handing off work.
The leadership team comes from aerospace and robotics backgrounds. Co‑founders Martin Bocken (CEO), Josef Rokusek (CTO), and Thomas Laporte (CBO) anchor a structure that includes a Head of Safety, a Head of Science with a Ph.D., a Head of Mechanical Engineering, and dedicated leads for GNC (guidance, navigation, and control), embedded systems, full‑stack software, industrialization, and operations. This structure shows engineering work lives in tightly coupled subsystems rather than siloed departments.
Zero G Talent's board shows HyLight actively recruiting for salaried roles, all based in Paris and Île‑de‑France. The postings break down by discipline:
| Role | Location | Salary Band |
|---|---|---|
| Quality Manager | Paris, IDF, FR | €55,000–80,000 |
| Embedded Software Engineer (Architecture & CI/CD) | Paris, France | €50,000–70,000 |
| Senior GNC Engineer | Paris, IDF, FR | €50,000–70,000 |
| Full-Stack Engineer | Paris, IDF, FR | $45,000–65,000 |
| Mechanical Integration and Test Engineer | Paris, IDF, FR | €45,000–60,000 |
| Electronics Engineer | Paris, IDF, FR | €45,000–60,000 |
The mix shows HyLight's priorities. GNC and embedded software top the list because the airship's autonomy and flight safety depend on them. Mechanical integration and test engineering reflect a shift from prototypes to repeatable production, where assembly and validation matter as much as design. Full‑stack engineering covers the dashboard that turns raw aerial data into actionable intelligence for utility customers. Electronics and quality roles signal that hardware reliability and sensor integration are scaling concerns, not afterthoughts.
HyLight wants engineers who thrive on innovation, autonomy, and impact, matching its structure where individuals own subsystems. Major European utilities such as SNCF, ENEDIS, NaTran, Terega, and Suez trust HyLight, so candidates must be comfortable working toward European flight certification standards, not just building novel prototypes.
HyLight has grown from approximately 10 employees in 2022 to 44 employees as of March 2026 (per Revelio Labs), and its current postings suggest it remains a small engineering team in Paris. This size means hires need to be generalists who can specialize quickly, someone who can write embedded code one day and sit in a test chamber the next. The hydrogen airship, with its extended flight endurance and millimetric inspection requirements, demands engineers who grasp both aerospace weight‑power limits and the software needs of persistent monitoring.
What It Pays
Revelio Labs reports an average of $86k across 44 employees, higher because many roles sit in Western Europe.
Engineering makes up the largest share of staff, and the posted roles reflect that focus.
Benefits follow French standards, which include insurance and retirement benefits, plus extra perks. HyLight covers 100 % of public‑transport passes, provides free daily lunches, and organizes regular team events and trips. Glassdoor notes that staff also receive insurance and retirement benefits, though the company does not publish detailed coverage levels.
The posted salary range and equity package fit a growing firm. HyLight's revenue is modest, and its hiring velocity rose from a small number to a few new roles per month, suggesting rising compensation pressure as it scales airship manufacturing and expands energy‑infrastructure partnerships.
How the Hiring Process Works
HyLight has no recruiting team. With fewer than 50 employees, the founders review applications while running the business. This shape means standing out matters more than polishing a résumé.
The process moves fast. HyLight's hiring cycle runs roughly seven days — faster than the ten‑day median for comparable climate‑tech and industrials startups, according to the Anti‑Job Board data.
Speed reflects a team that values initiative and quick iteration, matching the rapid development cycles proven with eight iterations of the HyLighter airship over several years.
Screening starts with the application. Reviewers reject generic CVs quickly, noticing recycled materials. Applicants should mirror the job posting's language and lead with the company's problems rather than personal ambition. HyLight focuses on growth and scaling production, so candidates who show they grasp that priority clear the first hurdle.
Following up matters. The median climate‑tech application gets no response, but a single follow‑up at day five roughly doubles reply rates. With no dedicated recruiters handling volume, visibility becomes the real challenge. Direct outreach wins.
The interview process is streamlined and technical. Glassdoor recorded four interview questions and three anonymous reviews, suggesting a focus on technical evaluation rather than multi‑stage corporate choreography. Given the roles posted, expect technical depth aligned to each discipline. The posted engineering roles signal technical rigor; the quality role focuses on production systems.
HyLight seeks speed, initiative, and bold ideas in interviews. The careers page says it hires engineers, designers, and operations talent who thrive on innovation, autonomy, and impact. Interview questions test whether candidates can handle real responsibility, the direct impact on cutting‑edge autonomous flight technology described in the postings.
The practical tip: don’t just apply and wait. Roles fill in days and founders personally review applications, so passive submission rarely works. Direct outreach — tailored to HyLight's scaling challenges around production standardization and airship reliability — draws attention in a process where every application passes through human eyes.
One tension: HyLight’s public materials stress collaboration and innovation, yet the hiring process reflects founder‑led triage more than structured team evaluation. Small teams move fast, but they also notice when candidates understand the real work ahead, scaling production to dozens of airships per year while eliminating tribal knowledge from manufacturing.
Where the Work Happens
HyLight's footprint blends software AI with hardware that flies. Headquarters sit in Le Plessis Pâté, a suburban commune just south of Paris in Île‑de‑France. This location houses the core engineering teams: embedded software, full‑stack, and GNC (guidance, navigation, and control) engineers who split their time between simulation work and hardware integration. Zero G Talent's live board shows salaried roles posted from this address, spanning Quality Manager, Embedded Software Engineer, Senior GNC Engineer, Full‑Stack Engineer, Mechanical Integration and Test Engineer, and Electronics Engineer. The posted roles indicate the compensation range.
What sets HyLight apart is its test infrastructure. The company operates from a base aérienne, an air base that doubles as office and flight‑testing range. HyLight pairs hydrogen‑powered airships with advanced sensors and AI, and inspecting pipelines over hundreds of kilometers at millimeter precision needs frequent, long flights. The air base provides runway infrastructure, airspace coordination, and hangar space to house and maintain these lighter‑than‑air platforms. The company says its airships can fly for hours without landing, enabling large‑scale inspection campaigns. Proximity to controlled airspace lets the team iterate flights without the logistical overhead of diverting to civilian airports.
The site does more than takeoffs and landings. The research record shows more than 150 flight hours logged, indicating an ambitious and operational test program. HyLight has developed several iterations of its drones dirigeables, a pace that demands a test loop for rapid prototyping, data capture, and redesign. Placing HyLight at the center of Europe’s energy‑infrastructure market, the air base’s location in France aligns with the region the company targets with its aerial data network.
Being based in Île‑de‑France means most roles require relocation to the Paris area. The work is not remote‑first; handling composites, pressure vessels, and flight‑control systems demands shop‑floor presence. Compensation packages listed on the board are competitive for the region, and the mission — decarbonizing infrastructure inspection by replacing helicopter‑based surveys with zero‑emission airships — shows how individual work adds up to sector‑scale impact. This split — global talent for AI and full‑stack roles, local test work for hardware — eases the hardware‑software tension.
For candidates, the work location splits into two layers. A software or embedded‑systems engineer will likely mix Paris‑based development cycles with periodic trips to the air base for flight‑test support. Mechanical‑integration or test‑engineering roles treat the air base as the primary station. The company’s lean size means each role carries broad responsibility, and the small sites let teams constantly share knowledge. A Quality Manager in Île‑de‑France may find themselves on the tarmac reviewing a pre‑flight checklist; a Full‑Stack Engineer may debug a telemetry pipeline that runs from a laptop in Paris to a sensor package hovering over a power grid. The office and test range are co‑located, and the hiring data reflects that proximity.
Who Thrives Here
HyLight says success depends less on pedigree and more on daily habits that match its values. The first clue comes from a LinkedIn post where the team shares its guiding principles: “Always act. Be authentic. Take pleasure.” [1] These habits show up in internal chats and guide daily work.
Bias toward action means HyLight rewards quick moves from idea to test. The firm notes it “flies as much as possible, innovates constantly and improves our solution quickly.” [2] In practice, this leads to scheduling frequent flight campaigns at Base Aérienne 217 in Brétigny‑sur‑Orge, iterating on hardware or software after each sortie, and treating each flight as a chance to gather data, not just a demo.
Authenticity appears in how HyLight describes its mission. The firm says its ambition is “to make our societies resilient to the effects of climate change by working on the crucial step of observation and inspection for a better understanding of our world.” [3] Staff who see leak detection as a real contribution to resilience feel more engaged. The same post calls enjoyment a core value, not a perk. Those who find genuine satisfaction in solving hard engineering problems, who enjoy collaborating across disciplines, and who can articulate why the work matters to them are more likely to thrive.
HyLight says its efficiency shows in a motivated, passionate team carrying daily this project with real societal impact." [4] This suggests successful employees combine technical rigor with a sense of ownership over outcomes. They stay comfortable in a small, fast‑moving environment where responsibilities shift quickly, and they draw motivation from seeing the direct effect of their contributions: whether a cleaner inspection report, lower greenhouse‑gas emissions, or a quieter flight path that respects nearby communities.
When a HyLight airship drifts silently over a gas pipeline at dawn, its sensors stitching millimeter‑scale leaks into a live map, the engineer who tuned its guidance software knows the same rigor that got them hired is now keeping Europe’s energy arteries safe.
