The shipping industry is notoriously difficult to decarbonize, accounting for ~3% of global CO2 emissions. If it were a country, it would be the 6th largest emitter in the world (ranking just above Germany).

Recent global regulations from the International Maritime Organization require ships to reduce their CO2 emissions by 40% by 2030, but there are currently no clean solutions available for them to do so. Alternative power sources like hydrogen, ammonia, methanol, and onboard batteries are still 10-20 years away from maturity for large ships and energy efficiency solutions can only reduce 5-10% of CO2 emissions.

About Seabound


Seabound captures CO2 emissions from ships.

We are building a retrofittable device that traps the CO2 from a ship’s exhaust gas. It has the potential to be one of the simplest, safest, and most affordable solutions for zero-emissions shipping.

To date, we have proven the concept on land and tested our capture device on a 3200 TEU container ship. We have secured 6 letters of intent from major shipowners to purchase our systems, raised ~$4.5M USD from top investors including Lowercarbon Capital and Y Combinator, and won a competitive grant from the UK government in the Clean Maritime Demonstration Competition. We are now recruiting a Mechanical Engineer to join our engineering team to help optimize and scale this new category of maritime climate tech.

Roles and responsibilities


To support our mission of decarbonizing shipping, you will be a key member on a team responsible for bringing Seabound’s first-of-its-kind onboard carbon capture equipment from proven prototype to scalable product. You will own the full hardware development life cycle of key components and systems, through the design, analysis, prototype, test, manufacturing and integration phases. Your work will directly prevent greenhouse gas emissions from entering the atmosphere and be instrumental in bringing the shipping industry to net zero.

What You’ll Do:

  • Sizing and design of mechanical, thermal and fluid parts and systems, including conducting trade studies, designing using CAD software, selecting off the shelf components and simplifying/improving existing designs

  • Perform analytical calculations using a variety of approaches (hand calcs, simple programs, FEA/CFD models, etc) to ensure system and component level requirements are met

  • Support and develop hardware test campaigns to anchor analysis with real world data, including test design, integration, operation and evaluation of results

  • Support and develop build processes while owning product delivery timelines

  • Collaborate closely with other engineers on the team; contribute to growing and building a strong engineering culture and team

  • Anything else that needs to be done in an early-stage startup

Skills and requirements


We are looking for:

  • Degree in mechanical engineering, aerospace engineering or related discipline and 1-3 years of experience in a design engineering role (exact title and compensation will reflect level of experience)

  • Strong engineering fundamentals in structures, materials and thermal/fluids

  • Hands-on experience building and testing real world parts

  • Experience with 3D CAD software and GD&T

  • Someone who is resourceful, ambitious, excited to tackle hard problems that no one has solved before, and holds themselves and others to a high standard

  • Someone who is passionate about decarbonizing the shipping industry and tackling the climate crisis

  • Ability to operate effectively under high degrees of uncertainty and to execute on tasks against tight timelines and aggressive schedules


  • (Bonus but not required) experience with advanced engineering calculations and FEA/CFD simulations

  • (Bonus but not required) familiarity with Python or MATLAB

  • (Bonus but not required) experience with design of bulk solids handling technologies

  • (Bonus but not required) experience leading the development of a new hardware product/technology

  • (Bonus but not required) experience owning significant responsibility in a fast-paced working environment

Seabound is an equal opportunity employer. We value diversity and strive to create an environment that is inclusive to all employees.
