Careers
At TEKJP, we are hiring people who will carry work forward with their own hands, from design through implementation to verification.
This is work where you move across the technical fields of BMS and flight computers, make full use of a state-of-the-art AI development environment, and build things that actually work.We are a company of engineers who place value on building with their own hands. We look forward to hearing from those who will walk alongside us in a cutting-edge development environment powered by AI.
Turning technology into reality
with our own hands.
TEKJP welcomes engineers with a broad perspective. We look forward to hearing from those who want to build things with their own hands using AI—anchored in a specialty while stepping out into adjacent technologies.
Developing at the cutting edge of the AI era
At TEKJP, we practice "AI-first development," bringing AI into every stage of our work. Using a state-of-the-art generative-AI environment built around multiple generative AIs, we dramatically accelerate firmware development, circuit design, documentation, technical research, and more. We have built a development structure in which a single engineer can expand what they are capable of.
By mastering AI, even junior engineers can lead complex projects and step fearlessly into fields outside their specialty.
TEKJP aims to be an organization that makes the most of the growth speed of this AI era and continuously raises engineers' market value.
The kind of people we're looking for
We look forward to hearing from those with the following attitudes and interests.
✓ People who place value on building with their own hands
✓ People interested in advanced technology fields such as drones, BMS, edge AI, and power control
✓ People whose instinct is to "try it myself first" rather than wait to be taught
✓ People who want to work with broad discretion on a small team
✓ People who care less about past titles or positions and more about what they will build next
