About The Position

Cyvl is a Boston-based tech startup revolutionizing the way civil engineering firms and governments map and manage transportation infrastructure. Our enterprise-grade hardware and software solutions leverage 3D mapping sensors to capture LiDAR, imagery, and GPS data, retrofitted to our customers' vehicles. This data is processed through our AI-powered cloud pipelines to generate actionable condition and geospatial reports, saving our customers time, money, and resources. We are in a phase of rapid growth, disrupting a massive and outdated market with our innovative solutions. At Cyvl, our mission is to empower governments to build and maintain public infrastructure they're proud of by accelerating decision-making through our sensors and Infrastructure Intelligence Platform. As our Senior Mechanical Design Engineer, you'll own the design of the sensor that makes all of it possible and help define what the next generation looks like as we scale production. We're a fast-moving, high-growth team that believes in solving real-world problems with authenticity, simplicity, and boldness. Every member of our team is empowered to take ownership, deliver results, and leave a lasting impact on the communities we serve. We're looking for a Senior Mechanical Design Engineer to own the hardware at the center of everything we do. Our sensor mounts to the roof of a customer's vehicle and stays there through winters, potholes, and the occasional car wash. The people installing it are usually DPW crews, not engineers. It has to survive all of that and still come back with clean data. The enclosure, chassis, thermal path, sealing, and mounting system are yours, along with the drawings and documentation that let someone else build it correctly a thousand times. This is a hands-on design role with real ownership. If you're motivated by hardware that holds up in the real world, this role is for you.

Requirements

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, but OnShape, Creo, or similar is fine
Experience designing for CNC machining, molded plastics, and 3D printing, and comfortable picking up sheet metal or weldments when a part calls for it
Has taken parts to tooling and shipped them, designing 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
Has worked directly with molders and tool shops through DFM review, tool kickoff, first shots, and tuning
Comfortable building, testing, and iterating on functional prototypes by hand
Experience with tolerance stackups, FAI review, and DFMEAs
Has followed designs through the production line, fixing issues in engineering builds, production builds, and the field
Experience managing revision control, change orders, and deviations 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
Willing and able to work from our Boston-area office 5 days per week

Nice To Haves

Experience designing 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: parts that look and feel considered, with finish, texture, parting lines, and fit that read as premium
Experience 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 you've designed; we'd rather see the parts than read about them

Responsibilities

Take designs from concept to production with our electrical, firmware, and perception engineers
Prove the design survives real life: structural and thermal simulation, vibration and shock, ingress and environmental testing
Design a mounting system a non-specialist can install on a wide range of customer vehicles without damaging them
Produce the drawings, GD&T, models, and BOMs that let someone who has never met you build it correctly
Decide what stays machined and what moves to tooling as volume grows, and run DFM with our molders
Own the product lifecycle process and its documentation, keeping the released design and the built unit in agreement
Troubleshoot mechanical issues across design, build, and field, and lead the work that raises unit reliability
Support the move to contract manufacturing: assembly documentation, fixtures, tolerance strategy, FAI, and early DFM with the CM
Meet relevant safety, vehicle-mounting, and quality standards, and hold the line on cost as we scale
