Hardware Engineer in London

Timebeat builds the infrastructure of time.

We design nanosecond-accurate synchronisation systems, hardware and software — that keep defence, finance, broadcast and 5G networks running on a shared, provable clock.

When a trading venue needs to prove the order of events to the microsecond, when a 5G network needs its radios phase-aligned, or when a defence platform needs to hold time through GNSS denial, our kit is what does it.

We're an engineering-led company with offices in London, Dallas and Ho Chi Minh City.

Our product line runs from OEM timing modules and PCIe timecards to fully resilient GNSS grandmasters — things like the Open Time Appliance Mini (a palm-sized grandmaster with battery holdover and a double-oven oscillator good to 1.5 µs over 24 hours without GNSS) and the White Rabbit Mezzanine (a sub-nanosecond OEM module hitting ~25 ps RMS jitter).

This is genuinely hard, high-precision electronics — mixed-signal design where picoseconds and clean power actually matter — and the products ship to demanding customers who notice the difference.

The role

We're looking for a hands-on Hardware Engineer to help develop high-quality electronic products from concept through to production.

You'll own real designs end-to-end — schematic through prototype bring-up, debug, and into manufacture — and see your work ship in products where timing performance is the whole point.

This is a great fit for someone who enjoys practical, real-world hardware development and wants broad ownership rather than a narrow slice of a big process.

• What you'll be doing
• Schematic capture and board-level design for new and existing products
• Mixed-signal, digital and power circuitry — where low noise and clean clocking are first-class concerns
• Prototype bring-up, testing and lab debugging
• Component selection and BOM creation
• Design for manufacture and production support
• Working closely with firmware, mechanical and product teams to get designs shipped

What we're looking for

• ~3+ years' experience in PCB or electronic hardware design
• Strong schematic capture and PCB layout in Altium Designer (or similar)
• Hands-on board bring-up, lab debug and test
• Experience designing digital and mixed-signal boards for commercial products
• Solid grasp of interfaces — SPI, I²C, UART, USB, Ethernet or CAN
• Good grounding in power design, EMC basics, grounding, decoupling and manufacturability
• A practical, problem-solving mindset — you enjoy getting hardware working
• Nice to have
• Processor-based or higher-speed digital design
• Exposure to FPGA-connected hardware
• Experience with precision timing, clocking, oscillators or low-jitter design
• Taking products through verification and into production
• EMC / compliance testing
• Work on genuinely hard problems — precision timing is a niche where the engineering actually matters, not incremental tweaks
• Real ownership — take designs from concept to shipped hardware, not a fragment of someone else's board
• Small, engineering-led team — your work has visible impact and you're close to the product and the customers
• See it ship — our hardware goes into defence, finance, broadcast and telecom networks worldwide

We're looking for someone thoughtful, hands-on, and who enjoys building reliable hardware in a fast-moving environment.
