Company Description
Fleetcraft is a $5.3M seed-stage London aerospace startup building AI infrastructure for aircraft maintenance and manufacturing.

Job Description
As a Founding Engineer at Fleetcraft, you will build the core AI systems that aircraft technicians use on the hangar floor.

Why this role is remarkable
- True founding-level ownership: You will decide the architecture, write the code, and witness real-world impact by working directly with technicians in the hangar.
- Tier-one backing: We have raised a $5.3M seed round led by Susa Ventures (early Anduril backers) and are on a fast track toward our Series A.
- Massive industry impact: You are modernizing critical infrastructure for an aerospace sector facing massive technician shortages and decade-long backlogs, where reliability is non-optional.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You Will Do
- Build and scale core MRO systems, managing everything from hands-free voice-capture maintenance records to complex workflow orchestration across maintenance operations.
- Design and deploy end-to-end AI agent systems using LLMs to transform maintenance manuals and airworthiness directives into trusted, actionable data pipelines.
- Lead technical reliability initiatives, including infrastructure, observability, and rigorous evaluation frameworks for AI within a regulated FAA/EASA compliant environment.
The ideal candidate
- 3+ years of full-stack experience using FastAPI, TypeScript, and React with a proven track record of shipping high-quality software at high velocity.
- Possesses a co-owner mindset and pragmatism, capable of taking a project from architecture to deployment with full autonomy over technical decisions.
- Highly adaptable learner with an interest in production AI systems; experience in early-stage startups, competitive programming, or building agents is a strong plus.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
