Careers
Digital Designer
ONiO builds microcontrollers that run without batteries — but that’s not the point. Our chips harvest ambient energy — light, heat, RF — and just work. No wires. No recharging rituals. No maintenance loops. We don’t believe batteries are evil. We just don’t assume they’ll always be there. Our first chip, ONiO.zero, is a wireless microcontroller built from scratch to run on harvested energy. It cold-starts from under a microwatt. It runs BLE and other radios.
We’re looking for a Digital IC Designer to help us push that platform even further. You’ll work at the intersection of design, power optimization, and system architecture — building chips that sip microwatts and still get the job done.
Responsibilities
- Design and implement digital logic for ultra-low-power microcontroller subsystems using Verilog
- Develop RTL for custom peripherals, bus interfaces (AHB/APB/AXI), and low-power digital blocks
- Collaborate with analog, mixed-signal, and software teams to shape system architecture
- Write and maintain simulation testbenches and coverage metrics for verification
- Analyze timing reports, set up synthesis constraints, and optimize for PPA (power, performance, area)
- Support silicon bring-up and debug using logic analyzers, JTAG, and firmware tools
- Document design specifications, reviews, and verification plans
- Maintain reusable IP blocks and continuously improve design flows
- Contribute to CI pipelines for RTL and test code (version-controlled)
- Support design closure, tapeout, and post-silicon validation phases
Requirements
- Solid experience with Verilog RTL design (5+ years preferred)
- Strong grasp of digital design fundamentals: FSMs, pipelining, CDC, timing closure
- Experience with SoC subsystems: timers, UARTs, I2C/SPI, GPIO, DMA
- Familiarity with low-power design techniques and microcontroller architectures
- Proficient with EDA tools: simulators (ModelSim, VCS), synthesis (Design Compiler), STA, linting
- Proficiency in Python for scripting, test automation, or tooling
- Version control experience (Git)
- Clear communicator, both written and verbal
- Degree in Electrical Engineering, Computer Engineering, or related field
Bonus skills
- UVM or formal verification experience
- Working with RISC-V architectures
- Experience with equivalence checking tools
Benefits
- Competitive salary and insurance, health & pension benefits
- Stock options — skin in the game
- The chance to shape real, cutting-edge products
- Fast-paced, diverse, design-forward environment
- Work-life balance, family-friendly policies
We know talent doesn’t come in neatly shaped lists. If you don’t tick every box but this sounds like your kind of challenge — apply anyway. We care about capability, curiosity, and attitude over perfection.
