Pressure Equipment Welder

Own and run Rivan welding and pressure equipment manufacturing.

Rivan Industries () is a synthetic fuel company designed to decarbonise heavy industry. We aim to make synthetic fuel cheaper than fossil fuels and sustain life on earth by keeping the CO2 locked underground.

We design and manufacture modular synthetic fuel plants consisting of a DAC system, an Alkaline Electrolyser, and a Sabatier Reactor, vertically integrating with off‑grid DC solar and the European gas‑grid. Here’s our manifesto on how we plan to do it. We’ve recently deployed the UK’s largest synthetic fuel plant and are planning to 1000× this scale in the next 2 years.

We have “increase iteration speed or die” up on the wall at our HQ. The success of Rivan is really down to the speed at which we can iterate through bad designs to something that has staying power. Since information is the bottleneck, our ability to quickly build everything from test‑rigs to full‑scale commercial assemblies is the difference between life and death.

We’re looking for an experienced pressure equipment welder to supercharge our build pace, vertically integrate, and accelerate our iteration speed. If you love building things, have an attention to detail, and feel shackled where you currently work – come and help us at Rivan!

• Help us design, build and certify critical pressure equipment
• High temperature reactors
• Pipework and manifolds
• Non‑pressure equipment welding
• Large scale sheet metal fabrications
• High temperature kilns
• Skid frame construction
• Fabricate commercial products and R&D equipment.
• Work straight from engineering drawings, with particular attention to tolerances. This includes working from high level design description (sketch, CAD model, description of work), requiring little input after initial description. Go and own it.
• Execute all the above with sound safety experience.

• Upskilling our existing and future team.
• An opportunity to learn. We need our manufacturing team to have a broad understanding of the design and manufacturing process. This requires a willingness to learn.
• Our manufacturing team is integrated into the engineering team. All members are involved from the earliest design stages. We’re after experienced manufacturing staff that are a source of knowledge and help guide on design for manufacture and assembly.
• We’d like this role to take the lead on coordinating with external contractors to implement solutions.

Specific welding expertise:

• Ideal example code requirement of ISO 9606‑1 141 T/P (plate and pipe) BW FM5 S PA ss gb or equivalent.
• Typical vessel and pipe work:
• Vessel wall thickness 3 mm to 10 mm
• Stainless steel (316L)
• 2+ years of pressure equipment vessel and pipework manufacture experience
• Experience with or working alongside pressure testing facilities and other quality control testing for the purposes of design certification.

• £40-60k Salary depending on experience
• Available immediately on a full‑time/ part‑time basis
• In‑person work at our HQ in Bermondsey, South London
• Private health insurance
• Unlimited time off

We encourage exceptional applicants from all backgrounds to apply for this role, even if they do not meet all the requirements listed.
