Hardware Engineer

About Timebeat 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 Why join us - 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.
