Vacancies - Join the Build

Franky, the Esp32 Synth, and Mirror are projects that explore the edges of real-time audio, electronics, and interactive systems.
We're not a corporate machine - just builders looking for other builders. Below are the roles we see as critical.
Clear scope, clear problem. No bait-and-switch.

1. Electronics Engineer - ESP32 Synth Boards (Remote)

Project: Esp Synth

Focus: Designing and building stable ESP32-based audio boards (DACs, MIDI, power).

Skills that matter:

  • PCB design & debugging
  • Power regulation, grounding, shielding
  • Mixed-signal (analog + digital) electronics

Skills that are desired:

  • Audio electronics experience
  • EMI/noise reduction knowledge

Engagement: Project-based - help design and stabilize boards for production.

2. Hardware/Physical UI Prototyper - Controls & Interfaces (Remote)

Project: Synth (collab with board designer)

Focus: Physical user interface - buttons, knobs, encoders, tactile feedback.

Skills that matter:

  • Prototyping hardware UI

  • Hands-on building mindset

  • 3D modeling for enclosures

Skills that are desired:

  • Industrial design, ergonomics
  • Integration with electronics

Engagement: Project-based - specific role in shaping the synth's hands-on interface.

3. Marketing & Outreach Specialist - Electronics & Audio (Remote)

Project: Franky + Esp Synth

Focus: Build visibility, apply to festivals/exhibitions, connect with collaborators.

Engagement: Ongoing but lightweight - exploration + comms.

4. Rust Developer - Async Systems (Remote)

Project: Franky

Focus: Writing async Rust code for real-time pipelines.

Skills that matter:

  • Solid Rust fundamentals\
  • Async/await, tokio
  • Pragmatic coding style (balance speed & precision)

Skills that are desired:

  • MIDI, audio, or real-time familiarity

Engagement: Part-time/project-based. Not looking for a guru - competent and pragmatic is enough.

5. Investor / Advisor - Business & Network

Project: Franky

Focus: Bring capital, connections, and business perspective.

Skills that matter:

6. Musician / Sound Designer - Co-shaping Franky's Sound (On sight)

Project: Franky Focus: Shape Franky's sonic identity and test its musicality.

Skills that matter:

  • Composition or performance
  • Open to experimenting with generative/interactive systems

Skills that are desired:

  • Synth/DAW/live performance experience

Engagement: Creative collaboration. Fit is important; tastes may differ, exploration is the point.

If one of these fits you - or you see another way to contribute - reach out. This is about building things that shouldn't exist yet, together.
