Hardware & Product Developer - LED Controllable Products

Hardware & Product Engineer CrowdSync Technology — New York, NYContract Freelance or Full Time CrowdSync Technology builds the LED wearables and live activations that turn concert and stadium crowds into part of the show. Our controllable wearables sync to music, lighting cues, and live moments across an entire venue — turning a crowd of thousands into one choreographed light show. We work with major artists and events, and we ship real hardware at real scale.We're looking for a Hardware Engineer to own products end to end: from a sketch on a whiteboard to tens of thousands of units coming off a line in Shenzhen.https://crowdsynctechnology.com/Develop new products — take wearables and event activations from concept through mass production.Push the product forward — improve cost, reliability, performance, and manufacturability of what we already ship.Own factory relationships — manage our overseas manufacturing partners, keep production on schedule and on spec, and be the person who makes the line run.Design PCBs and firmware — and lean on modern AI-assisted coding and design tools to move faster than a team our size normally could.Wear a lot of hats — board bring-up, DFM reviews, chasing down a flaky RF link, debugging a bad batch. Whatever the product needs that week, you're on it.What we're looking forHands-on hardware experience across PCB design and embedded firmware.Experience working with overseas factories, specifically in China and Shenzhen, you know how to communicate specs, manage tooling, hold quality high, and keep things moving across a time zone and a language barrier.Comfort using AI-assisted workflows for firmware and PCB development.A strong bias toward action — you'd rather ship, learn, and iterate than wait for perfect.The ability to juggle a full plate and self-direct in a small team, without a lot of hand-holding.This is an entry- to mid-level role. We care more about drive, resourcefulness, and how fast you learn than about years on a résumé. The right person will take on a lot, grow fast, and make real moves on their own.Nice to haveRF / wireless experience (sub-GHz, BLE). (must be able to learn and become an expert quick!)LED driver, low-power, and battery design.DMX or live-event / lighting-production background.Experience taking a consumer hardware product through certification (FCC/CE) and into mass production.Why CrowdSyncReal ownership. Small team, big scope — your work ships, and you get to watch it light up an arena.Steep learning curve. Fast pace, lots of responsibility, and the autonomy to make things happen yourself.A front-row seat to live events, major artists, and hardware that thousands of people hold in their hands.Comp: Starting at $70,000 - $85,000 base on experience.
