We hire people who would rather build than pitch.

Open roles

• Firmware engineer

  €70k–95kRemote, EU timezones

  Own the firmware on Spark: the display pipeline, the DNS observer, and the provisioning flow that binds a device to a household with no cloud account in the middle. MicroPython, tight C, and hardware you cannot easily reach are all useful here.

• Privacy researcher

  €65k–90kRemote

  Design and run the measurement studies published on our research page. You would own the methodology, the apparatus and the write-up, including the parts that did not work. Prior work in measurement or network security expected.

  Full time Apply →

• Product designer

  €55k–80kRemote

  Design for people who are already suspicious of the software asking for permissions. The bar is legible defaults, no dark patterns, and an explanation for every state the device can be in.

  Full time Apply →

• Backend engineer

  €60k–85kRemote, EU timezones

  Build the provisioning service, the order pipeline and the public status page. A deliberately dull stack: we would rather spend the complexity budget on the device than on the server beside it.

  Full time Apply →

• Technical writer

  €40k–55k pro rataRemote

  Write the documentation that ships with the device and the teardowns that ship after it. Someone who can explain ECDSA identity provisioning to a cautious non-engineer without dropping the part that matters.

How hiring works here

1. You write

   One email, whatever the role. No cover letter, no application portal, no login.

2. We reply

   Within a week, yes or no. A no still gets a reason you can act on.

3. You talk

   One call about the work and how you would approach it. No whiteboard puzzles.

4. We try it out

   Paid, scoped, and yours to keep. Timeboxed to a week and never used as a test of loyalty.

5. Offer or no

   In writing, with the band named in full before you are asked to decide anything.
