Job Summary

ABOUT CYVL

The best infrastructure is invisible. You only notice it when it fails. For decades the people responsible for our roads bridges and sidewalks have been asked to manage the physical world with tools that cant see it.

Cyvl is the Physical AI company changing that. We build purpose-built sensors computer vision and AI that turn every drive into current data: what exists where it is and what condition its in. 500 cities and towns use our Infrastructure Intelligence Platform to direct the work and fix problems before they fail. 1 in 30 Americans drive on roads managed with Cyvl data.

The proof isnt a dashboard. Its a smoother commute a safer walk to school and public dollars going where they matter most. Were a fast-moving team in Boston building hardware software and AI for the real world. If you believe technologys highest calling is public good come build with us.

THE ROLE

Our sensor mounts to the roof of a customers vehicle and stays there through winters potholes and the occasional car wash. The people installing it are usually DPW crews not engineers and it still has to come back with clean data. As our Senior Mechanical Engineer youll own the enclosure chassis thermal path sealing and mounting system plus the drawings and documentation that let someone else build it correctly a thousand times. This is a hands-on design role with real ownership as we scale into production.

WHAT YOULL DO
  • Take the sensor from concept to production with our electrical firmware and perception engineers including a mounting system a non-specialist can install on a wide range of vehicles without damaging them.

  • Prove the design survives real life: structural and thermal simulation vibration and shock ingress and environmental testing.

  • Produce the drawings GD&T models and BOMs that let someone who has never met you build it correctly and own the lifecycle process that keeps the released design and the built unit in agreement.

  • Lead the move from machined parts and in-house builds to tooling and contract manufacturing: DFM with molders and CMs assembly documentation fixtures tolerance strategy and FAI.

  • Troubleshoot mechanical issues across design build and field raise unit reliability and hold the line on safety quality and cost as we scale.

WHAT YOU BRING
  • BS or MS in Mechanical Engineering or a related field with 3-7 years of experience ideally in robotics automation automotive or ruggedized electronics

  • Cradle-to-grave design experience with precision-machined and molded parts (SolidWorks preferred; OnShape Creo or similar is fine)

  • Experience designing for CNC machining molded plastics and 3D printing and comfort picking up sheet metal or weldments when a part calls for it

  • Parts taken to tooling and shipped designed for the mold rather than just in plastic: draft parting lines and gates shrink and warp ejection and resin choice for years of sun and road grime

  • Direct work with molders and tool shops through DFM review tool kickoff first shots and tuning

  • Comfort building testing and iterating on functional prototypes by hand

  • Experience with tolerance stackups FAI review and DFMEAs and following designs through engineering builds production builds and the field

  • Revision control change orders and deviations managed in a PLM system or a disciplined equivalent

  • Thermal management of electronics inside sealed enclosures and sealing to a real IP rating

  • Strong judgment on design performance and logistical tradeoffs and clear technical documentation

NICE TO HAVE
  • Enclosures for a standard autonomy stack: cameras GNSS LiDAR IMUs and edge compute

  • Vehicle-mounted or automotive accessory hardware including roof-rack rail and magnetic mounts

  • Optical window design sealing and keeping glass clean in a road environment

  • An eye for beautiful well-designed components with finish texture parting lines and fit that read as premium

  • Taking hardware from low-volume in-house assembly to contract-manufactured production

  • Hardware deployed into government public-sector or other regulated environments

  • A portfolio or photos of hardware youve designed; wed rather see the parts than read about them

WHY CYVL

Hard tech. Real streets. Your name on it.

  • Hard problems in the real world. You build end-to-end: our own hardware software and AI with work that shows up on the street in the real world.

  • Ownership that compounds. You own outcomes not tasks. You work directly with customers and across our team and youll own more sooner than almost anywhere else.

  • Intense with heart. Were building a category so its not a place to coast. We also take care of each other have genuine fun together and believe in what we are doing.

WHAT WE ASK
  • Cross lanes. Not my job doesnt exist here.

  • Own without a playbook. The plan is still being written often by you.

  • Try miss try again. We make big bets. Some wont land and we learn fast.

  • Be in the room. Were on-site in Somerville about 90% of the time.

Were a startup building a category. If that sounds like the draw not the risk wed love to talk.

BENEFITS
  • Equity. Youll own a piece of what youre building.

  • Health dental and vision. Cyvl covers most of the premium for you and your family.

  • 401k with a real match vested day one. Your money is yours from the start.

  • Generous PTO & Paid Parental leave. Doing hard work well includes stepping away from it.

  • Learning stipend. Spend it on whatever makes you sharper.

  • Paid to live close. A monthly bonus for living near our Boston office.

  • Team events. Time together in Boston with a team youll love working with.

OUR VALUES
  • Real: Authentic and transparent. Focused on solving real problems with simple effective solutions.
