Project Engineer, Engineering Design & Technologists

$150-180K base + meaningful equity (flexible on the mix). Relocation support available.

Anvil Capture Systems is a Somerville, MA-based startup working to commercialize our novel carbon removal technology. Anvil’s process is uniquely provable, affordable, scalable, and safe, making Anvil a highly competitive entrant in the CO2 removal sector. Anvil is based at Greentown Labs, the largest climate tech incubator in the world.

Reporting directly to Anvil’s co‑founders, the Project Engineer will be the driving force behind designing, building, and commissioning Anvil’s commercial pilot, a first‑of‑a‑kind system. This isn’t a typical engineering role. You will be the company's primary owner of this system, with the responsibility and satisfaction of taking it from design through commissioning to operation.

The ideal candidate brings significant materials handling experience and a mechanical engineering background. You might have titles like Project Engineer, Mechanical Engineer, or Process Engineer on your resume, but what matters most is your hands‑on approach and track record of getting complex systems built and running.

Based at Greentown Labs in Somerville, MA, you’ll start fully onsite before transitioning to frequent travel for on‑site management of our commercial pilot builds at locations across the US.

• Develop the design for our commercial pilot system, working closely with Anvil's co‑founders and third‑party engineering firms
• Manage relationships with vendors, EPCs, and fabricators to ensure successful project execution
• Oversee commissioning and start‑up of the system, troubleshooting and solving problems as they arise
• Own significant aspects of the overall project, from preliminary through detailed design work
• Spend substantial time initially in Somerville, MA, with extensive travel to our future field sites once construction begins
• Be the company's eyes on the ground ensuring the system gets built correctly, on‑time, and on‑budget

• 7+ years of experience (flexible for the right person)
• Strong materials handling experience, particularly with bulk solids
• Background in mechanical and process engineering
• Experience with reactions and material conveyance
• Track record working in low‑margin industries where cost consciousness is critical (cement, grain handling, mining & processing, iron & steel, or similar)
• Proficiency with Solid Works
• Ability to produce P&IDs, mass and energy balances, process flow diagrams
• Strong fundamentals across thermodynamics, heat and mass transfer, load calculations, fluid flow, etc.
• Experience managing fabricators, vendors, or EPCs through design and commissioning phases of project development
• Experience with projects in the $1M–$100M CAPEX range
• Work on core teams of 3‑15 people where you owned significant design and project aspects
• Projects with 1‑3 year planning and deployment timelines
• Design‑through-start‑up experience with first‑of‑a‑kind, one‑off, or customized systems

• Equipment exposed to harsh environmental conditions (desert, high UV, temperature extremes)
• Large equipment with dimensional tolerance considerations
• Water‑saving and heating/cooling system design

• Full of energy and extremely hands‑on; a person who leaves no stone unturned, no details overlooked
• Upbeat with a "let's solve it" attitude
• Excited by significant responsibility and ownership
• Demonstrated leadership ability (on the job, in sports, or elsewhere)
• Ready for extensive travel and time split between Boston and remote locations
• Comfortable working in a fast‑paced environment where you'll need to make decisions and drive solutions
