Job description

About Seamflow

We’re removing one of the last great barriers to progress in the physical world. While software moves fast, industries like healthcare, aerospace, and energy are still slowed by outdated, manual systems.

Our vision is to unlock enormous value for Testing, Inspection, and Certification customers globally. The market is vast, the problem is real, and we're just getting started.

We're rapidly growing with mid six-figure revenue and a 14x oversubscribed $4.5M seed round backed by Tier 1 investors including Northzone and Initialized Capital. These funds backed the founders of Coinbase, Reddit, Klarna, and Spotify.

We're seeing significant traction in the market; demand is outstripping our supply, and we're building fast to keep up.

The Team

Our team includes former unicorn founding engineers, as well as former X, Google, Amazon, Yandex, and McKinsey employees. We are looking for people who move fast, think clearly, and hold themselves to a high bar. The standard here is genuinely high, and we're looking for someone who raises it further.

The Role

This is the role you take if you want to start your own company one day.

We're hiring a Founder's Associate to work directly with the founding team on the highest-priority problems across the business. It's a full-time generalist role: part strategist, part operator, part whatever-needs-to-get-done. You'll have a front-row seat to every part of building a company, with real ownership and real responsibility.

If you've spent time at McKinsey, BCG, Bain, or a top investment bank and found yourself wanting to build something rather than advise on it, this is the next step. You'll move faster, own more, and learn more here than anywhere else.

Right now, our biggest challenge is converting a strong pipeline into closed deals. A lot of that work falls to the founding team, and we need someone who can take real ownership of that process alongside us.

We're looking for someone who is high slope: gets up the curve fast, thrives in ambiguity, and is willing to get their hands dirty across whatever the business needs. The work will be varied, sometimes scrappy, and always meaningful.

What You’ll Do

You'll work across the full business, going deep wherever the founders need leverage. You'll work with the CEO, CTO, and Chief of Staff on a daily basis.

• Sales: Work directly with founders on customer conversations, synthesise insights, prepare materials, and help move deals to close.

• GTM: Shape both strategy and execution of products in the pipeline.

• Product: Gather deep customer insights, support discovery, map workflows, and collaborate with engineering on regulatory requirements.

• Fundraising: Support outreach, build materials, prepare updates.

• Expansion: Conduct market research and help define our expansion strategy.

• Hiring: Lead hiring ops as we continue to grow our team.

• Operations: Own internal workflows across legal/admin, tools, compliance, vendor management, and whatever the company needs to keep moving fast.

What We’re Looking For

• 2–4 years at MBB, a top-tier investment bank, or a high-growth startup in an analytical or operational role.

• Exceptionally organised with an obsessive attention to detail.

• Sharp analytical thinker — fast on your feet, intellectually curious, quick up the learning curve.

• Comfortable with ambiguity and proactive about solving problems that don't have a defined brief.

• Willing to get your hands dirty and do what needs to be done, however big or small.

• Strong with slides, Excel, and written communication.

• Someone who wants to be in the room, not on a call. This role is in‑person, full time at our Shoreditch office.

What You’ll Get

• The closest thing to being a founder without starting your own company

• Hands‑on exposure to every part of building a business

• A team that moves fast, works hard, and backs each other fully

• Competitive compensation package

• Lunch and dinner covered, 24/7 gym access, relocation support if needed
