Stratum is an AI startup founded by AI researchers, civil engineers and software engineers. Engineers do essential work, but too much of it is repetitive, manual, and slow. We are building the technology to change that, placing AI at the heart of every engineering discipline, dramatically accelerating how quickly things can be designed, assessed, and built. The knock-on effects matter: faster infrastructure delivery, better climate resilience, and economic growth.
We are a fast growing start-up in active commercial trials, and building out our commercial team. The work you do in the next twelve months will shape the next ten years of the company, as such this is not a typical 9-5 role.
The role
This is a hybrid role, based in L ondon, Bristol or Bath, at the centre of our commercial engine. You will own the relationship with our early customers - running trials, supporting live flood risk projects on the platform, and feeding what you learn back into product and sales.
Stratum sells to chartered engineers. We want someone who’s been there, and chose digital transformation over repetition. Someone who believes engineering can, and should, be better.
If that is you, read on.
We are looking for a T-shaped individual: depth in flood risk and the discipline of civil engineering, breadth across customer success, project support, and an active hand in sales. Over time the role specialises; you will help us decide how.
What you will do
* Run customer trials end-to-end. Scope each trial with the customer, set success criteria, train their team on Stratum, and drive towards a paid subscription. You are the customer’s main point of contact through the 30-day window.
* Support live flood risk projects on the platform. When a customer’s engineer is producing a real FRA on Stratum, you are the person they reach for. You can answer the substantive engineering question, not just the UI one.
* Be the customer voice inside the company. You sit closer to working engineers than anyone else. Engineering, product and the founders will rely on you to know what is actually painful, what is misunderstood, and what would move the next deal.
* Support sales. You will join discovery calls, run technical demos, contribute to proposals, and pick up parts of the sales motion that need engineering credibility in the room. As trials mature you will increasingly own the path from trial-end to signed Order Form.
* Build the playbook. There is not one yet. How we onboard, how we measure trial success, what a good check-in looks like, how we hand from CS to sales and back - you will write it.
What we are looking for
These are all the things we are looking for. You won’t meet every requirement. What matters is having enough of it, and the drive and resourcefulness to pick up the rest.
* 5-6 years of relevant experience in civil engineering, environmental consultancy, or an adjacent discipline. Proven hands‑on experience producing or reviewing assessments.
* Chartered with a relevant body - ICE, CIWEM, IEMA or similar environmental chartership. Most candidates we end up hiring for this role will be chartered individuals; if you are working towards it, tell us where you are.
* Strong working knowledge of Flood Risk Assessments or a closely related discipline. You can read an FRA, pinpoint the issues, and articulate them clearly to planning officers, consultants & developers.
* A real interest in digital technology applied to engineering. You do not need to code, but you need to be genuinely curious about how AI and software change the way this work gets done. People who view the platform as a threat to the craft are not the right fit; people who view it as a lever and opportunity.
* Customer‑focused, with a technical edge. You enjoy being the bridge between users and product. You can talk credibly to a leader at a tier‑1 consultancy and also sit with an engineer for an hour helping them get their first project through the platform.
* T‑shaped. Depth in flood risk; broad across customer success, project delivery and sales. Comfortable that the role is a mix and that the mix will change as we grow.
* Confident communicator. Most of the job happens in writing or in front of customers.
* Comfortable with ambiguity. Early stage means the playbook is still being written. You will help write it.
You will be a great fit if
* You aim high and deliver. You have a history of holding yourself to an exceptionally high bar and excelling, whether professionally, or personally. You are driven by a desire to be part of a high performing team that succeeds together doing career‑defining work.
* You are a team player first. We believe a small team of high performers is exponentially more impactful than the sum of its parts. You communicate with clarity, and you understand that we only succeed together. You make the people around you better.
The role is not for you if
* You need a highly structured environment. We are in the ambiguous, chaotic, and thrilling phase of 0‑to‑1. You will be creating the structure, not operating within it.
* You are not comfortable with AI tooling. We expect you to actively use AI tools and leverage the latest models to maximise your productivity.
* You want a predictable 9‑to‑5. We're building an extremely ambitious company at speed, and the work is regularly intense and demanding, there are times we pull together when it counts. We do value work/life balance and protect recovery between those pushes, but if a steady, predictable week is what you need, this isn't the role.
Nice to have
* Experience at a tier‑1 consultancy (Arup, Atkins, Jacobs, WSP, Arcadis or similar)
* Experience working with or inside a Lead Local Flood Authority
* Familiarity with GIS tools and Reference Data sources (Ordnance Survey, ESRI, BGS, EA / Defra)
* Previous customer‑facing, sales, or pre‑sales experience in a software or consultancy context
* Worked at an early‑stage startup before and know what that actually means
Why this role
You will be one of the first commercial hires at a company building a product that fundamentally changes how flood risk and other assessments get produced. If you are a chartered engineer who has been wondering whether the next ten years of your career should look different from the last ten - this is that opportunity.
