 Role: Senior Back-End Engineer
 
 
 Location: London
 
 
 Work Pattern: Hybrid (3&ndash;4 days onsite)
 
 
 Salary: &pound;115k&ndash;&pound;125k + Equity
 
 
 
 
 
 Wedo is partnering with a venture-backed AI company building next-generation agentic systems designed to automate complex workflows across global manufacturing, procurement and supply chains.
 
 
 
 
 
 Whilst much of the market is focused on copilots and productivity tools, this team is building AI capable of executing entire business processes autonomously. Their customers generate terabytes of complex data across ERP systems, supply chains, suppliers and manufacturing operations. The challenge is turning that fragmented information into intelligent systems capable of making better decisions at scale.
 
 
 
 
 
 The business is still early in its journey, but product-market fit is established, they have enterprise customers and now need to scale aggressively. They have just landed Series A, have plans to hire 65 and this role will specifically work with their Founding Engineer who&rsquo;s ex Meta and their CTO who&rsquo;s ex OpenAI.
 
 
 
 
 
 They're looking for a Senior Back-End Engineer who enjoys solving difficult technical problems, building robust systems and working closely with customers to bring ambitious ideas into production quickly.
 
 
 
 
 
 Current stack:
 
 
 &bull; Python
 
 
 &bull; Kubernetes
 
 
 &bull; Docker
 
 
 &bull; Terraform
 
 
 &bull; AWS
 
 
 &bull; GraphQL &amp; REST APIs
 
 
 &bull; Kafka
 
 
 &bull; LLM-powered systems
 
 
 
 
 
 The team is small, the calibre is high and you&rsquo;ll get to work with folk who have worked for Nasa, McKinzey, OpenAI, Meta, Revolut, Zilch.
 
 
 
 
 
 They're particularly interested in engineers who
 
 
 :
 
 
 &bull; Have strong commercial experience building production systems in Python
 
 
 &bull; Have worked with large-scale data processing, integrations or distributed systems
 
 
 &bull; Can take an ambiguous problem and turn it into a production-ready solution
 
 
 &bull; Enjoy customer interaction and aren't afraid to jump on a call to solve problems
 
 
 &bull; Want exposure to AI-native product development without necessarily needing prior AI experience
 
 
 &bull; Prefer ownership and accountability over rigid process
 
 
 
 
 
 The environment is ambitious, high ownership and highly collaborative.
 
 
 
 
 
 You'll have direct exposure to customers, founders and technical decision making. Engineers here aren't handed tickets. They're expected to understand the problem, shape the solution and own the outcome.
 
 
 
 
 
 Expectations:
 
 
 
 
 
 The team works hybrid with typically 3&ndash;4 days each week spent either in the London office or working alongside customers.
 
 
 This isn't a clock-in, clock-out environment. It will suit someone who enjoys early-stage company building, moving quickly and having meaningful influence over product and technical direction.
 
 
 In return, you'll get the opportunity to work on genuinely challenging engineering problems whilst helping shape how AI is deployed within large enterprise environments.
 
 
 
 
 
 Probably best suited to either:
 
 
 &bull; Someone looking to accelerate their growth by joining a high-calibre company at an inflection point
 
 
 &bull; Or someone who's already operated in early-stage businesses and enjoys the pace, ambiguity and ownership that comes with building products from the ground up

IT Developer

Improbable

<div>Improbable is a Venture Builder. We are working with leaders to create businesses in AI transformation, the metaverse and web3. We both create businesses from scratch and invest in existing businesses. Our central services teams work with ventures to help them achieve success; including early stage prototyping and initial product development where this role sits.
At Improbable, you are surrounded by people who want to improve everything and everyone around them, and who compel you to improve yourself. We&rsquo;re motivated by the fulfilment of solving hard problems to achieve something profound and transformative.<div></div> 
Your Mission
As a Senior Full Stack Engineer at Improbable, you will work with Ventures to help them get to market faster. You will work with their leadership team, to design, prototype and launch initial versions of their product. This is a hands-on, strategic role where you will collaborate with executives, working all the way from identifying customer problems.
About the Role
We're looking for a Full-Stack Engineer to build across the breadth of what Somnia ships, from consumer-facing products to developer technologies to internal platform and tooling. One month that's a polished end-user app, the next it's an SDK, a CLI, or the internal systems the rest of the team builds on.
This is a role for someone who cares as much about the product as the code.
You'll own the full lifecycle, from rapid prototyping to deployment. You use AI tools as a multiplier and like shipping end-to-end.
What you&rsquo;ll be doing<ul><li>
Design and build production-grade products end-to-end&mdash;back-end through UI&mdash;across consumer apps, developer-facing technologies and internal platform tooling.</li><li>
Build the high-performance back-ends and services these products depend on.</li><li>
Create developer technologies&mdash;SDKs, APIs, CLIs, libraries and starter kits&mdash;that make the platform easy to build on.</li><li>
Build internal tooling and platform infrastructure that raises the velocity of the whole team.</li><li>
Work self-directed: watch the ecosystem and the team's needs, spot gaps and propose and build what moves things forward.</li><li>
Work with DevRel, Marketing and BD so what you build lands with users and developers and fits go-to-market.</li></ul>
What we&rsquo;re looking for<ul><li>
Strong TypeScript across the full stack&mdash;this is the core of the role and our app stack. Some Golang where it fits.</li><li>
Build high-quality, production-ready frontends.</li><li>
Strong back-end engineering&mdash;APIs, services and the data layer behind them.</li><li>
Genuine interest in crypto and on-chain products.</li><li>
Strong ownership and self-direction&mdash;you generate ideas, not just execute them.</li><li>
Able to turn the dial: prototype fast and loose to prove a feature out, then shift into steady-state mode to harden what's worth keeping&mdash;tests, edge cases, reliability.</li></ul><div></div>
