How we know
It hasn't been reposted, listed twice, or left up unusually long, and the posting doesn't say it's a talent pool.
Ghostless records the day it first sees a posting, so a repost can't reset its age. This one was already up when Ghostless started tracking Twentyfour Industries.jobs.personio.com, so its true age is longer.

Not stated: Pay, real vacancy, AI screening.
Why these three
Ontario requires postings from employers with 25 or more staff to state the pay, whether the vacancy exists, and whether AI screens applicants.
Some employers add pay only on their own site. Check the original posting before you rule it out.

About the role
What weâre looking for
- Around 3 years or more of professional full stack development experience .
- Hands-on production experience with React, TypeScript , and Tailwind CSS. This is the core of the role .
- Backend experience in Python, or the clear ability to pick it up quickly .
- Respect for UI and UX ( user interface and user experience ) work . You do not need to be a designer , but you take design feedback seriously and you give the details the time they need .
- The ability to own a feature end to end: the data model , the API, the interface, and the tests .
- Comfort with Linux, Git , and a CI pipeline .
- Strong written and spoken English. German is a plus.
The day-to-day
- Build and maintain our ground control station : the operator view , the map , the live video , the controller integration , and the messages that tell an operator what the aircraft is doing .
- Build internal tools for the engineering teams , from data views to small applications that remove manual work .
- Work across the whole stack : a Python web backend, a typed API, and a modern web frontend, with most of your time on the frontend.
- Turn design direction into polished interfaces , and bring your own ideas on what goes on the screen, what does not, and what has to be visible at a glance .
- Work with the autonomy , perception , platform , and testing teams , who supply the data your interfaces show .
- Take feedback from pilots and test engineers , and turn it into changes they notice .
- Contribute to the customer-facing web applications as those begin .
You should apply if you
- Have experience with Vite and with typed API clients generated from OpenAPI .
- Have experience with FastAPI , Pydantic , or SQLAlchemy .
- Bring experience with map-based or real-time interfaces : live telemetry , video streams , or anything where the screen must keep up with a moving system .
- Can navigate building interfaces for operators , pilots , or control rooms , where a wrong click has a cost .
Nice to haves
- Experience with interfaces that must work outdoors , offline, or on an unreliable network.
- Experience with more than one language in a product interface.
- Experience deploying web applications to a cloud platform .
- An interest in drones , robotics , or defense technology .
