Senior Software Engineer in Slough

Our Mission
We’re fixing the most broken process in business. Whether it’s SaaS, hardware, or contractors, a typical B2B purchase drags on for 3+ months, spawns 50+ emails, and pulls in multiple stakeholders across Finance, Legal, Security, and IT. Nobody likes it, and it slows businesses down. Omnea exists to change that. Our AI-native platform connects the people, steps, and systems so buying just works. Employees have one place to make requests, the right approvals run automatically, renewals and supplier risk checks are handled on time, and leaders get clear visibility into how, when, and why money is being spent.

This matters more now than ever: volatile markets demand capital efficiency, businesses who adopt AI quickly have a competitive advantage, and evolving regulation demands evidenceable controls—so buying has to be fast and compliant by default.

Founded in 2022, we’re trusted by global enterprises including Spotify, Adecco Group, Albertsons, Wise, MongoDB, and Monzo. Our team previously built Tessian (backed by Sequoia; acquired by Proofpoint) and we’ve raised $75M from Khosla Ventures, Insight Partners, Accel, Point Nine, and First Round.

What we’re looking for
We’re looking for an exceptional, product-minded software engineer to join our engineering team & help scale Omnea with us. Our team will grow from low double-digit to 200+ enterprise customers and through 10x revenue growth...all in the next 2-3 years! You will support us in driving the growth of our product, team, and company through each chapter as we go from ‘start-up’ to ‘scale-up’.

You’ll be joining us at a pivotal time. We’ve just raised $50M in Series B funding from Khosla Ventures, Insight Partners, Accel, Point Nine, and First Round Capital. In the past year we’ve grown revenue 5x, tripled our customer base, and maintained >99% retention with enterprises like Spotify, Wise, Albertsons, Adecco, and McAfee. Our team is small but high-calibre — it took over 10,000 interviews to hire our first 50 Omneans.

Now we’re scaling fast and building the category of AI Supplier Relationship Management. And we are looking for the best software engineers out there to help turn procurement into a true competitive advantage!

We care more about skills than years of experience, but for your calibration, typically we’d expect candidates at this level to have around 8-10+ years of software engineering experience. We also have Staff and Principal level roles open if this role is the wrong level for you!

We’re generally flexible on your technical background in terms of the stack you’ve worked with, but you should be prepared to undertake our pair-programming stage of the interview process in Javascript or Typescript and be assessed on that basis. We’re also open to folks who fall more heavily on the front-or-back-end side of the software development spectrum, as long as you’re happy to ramp up into a truly full-stack role here at Omnea!

What Can You Expect in our Tech team?
Join a Skilled Team. You’ll become part of one of Europe’s fastest growing early-stage companies, working alongside a team of experienced full-stack product engineers who were all high performers at some of the best tech companies out there.

• Direct Product Impact. You will be involved in key product decisions, including prioritising our product roadmap, defining project scopes, and technical direction. You’ll have a significant voice in discussions about product strategy, user experience, and technical feasibility, making sure we steer our product roadmap towards success.
• Work with Modern Tech. Omnea is fully built on cloud-native and serverless technologies. Our primary stack is based on Typescript with React & Material UI, Postgres, Hasura and AWS Serverless Technologies such as Lambda, DynamoDB and EventBridge - all managed via AWS CDK & SST. We use Sentry, Lumigo and LogRocket for observability and Github Actions for automated testing and deployment.
• End-to-end Ownership. You will be entrusted with end-to-end ownership of your projects. From product, design and architectural decisions, all the way to deployment, monitoring and measuring impact on users. You will work across the stack, covering everything from DevOps to styling. We expect each other to take initiative, be proactive in problem-solving, and continuously seek improvements.
• Continuous Delivery. We embrace continuous delivery to keep our systems agile, responsive and safe. You will be deploying small, incremental changes to production multiple times per day, ensuring a constant flow of improvements and rapid adaptation to any customer needs or technical challenges.
• Tackle Scalability Challenges. As we grow our customer base from tens to hundreds and expand into new product domains, you will help us scale our product, architecture and processes efficiently while maintaining performance and reliability.
• Collaboration & Autonomy. You will often work autonomously to take charge of your projects, make decisions, and drive your work forward. But as a lean and high trust team, we remain quick to collaborate and support each other with challenging problems together.
• Customers at the Centre. Being really responsive to customer feedback and issues is key. We actively encourage engaging with customers, understanding their experience, and iterating our products based on their input to deliver solutions that truly delight them.

About You
You’re experienced (not a hard rule, but typically 5+ years) with building web apps having designed and implemented features from start to finish (ideally full-stack, using Typescript and AWS). You focus on having a high impact. You’ve spearheaded the engineering of critical systems before, working with best-in-class tooling in AWS, IaaC, observability and quality assessments. You want to discover the best ways to bring this to an early-stage startup.

You know what good can look like. You understand what it takes to build highly reliable & well architected products. You build with quality, observability & redundancy at the forefront. You’re ready to get a lot done. You enjoy all aspects of building a product and are comfortable moving across the stack when necessary. You enjoy problem solving and thinking from first principles. You’re ready to pick up new skills and build quickly.

You’re someone who craves ownership. Maybe you find yourself gravitating towards the meatier engineering projects or you want to level up DevOPS or SRE game. If there’s an opportunity to work on something bigger, you’re keen to take it on. You’re a team builder. You’re a team player. You’re excited by helping maximise team performance, whether that requires you to learn from others or to take the time to explain things, provide actionable feedback, and level up those around you.

You’re comfortable when faced with ambiguity. You’re happy to tackle problems without a predefined clear definition or obvious solution, and are excited to have autonomy to make decisions as you go, all whilst having the support of an experienced team alongside you.

Nice to haves that really stand out to us
You’ve performed exceptionally at something else in the past, be it academics, sport, work etc. You’ve gone above and beyond the norm. You love engineering, it’s more than a job for you. You’ve contributed to open-source projects or worked on side-projects in your spare time just because you enjoy it. You’re confident in your ability to tackle ambiguous problems and crank out quality code.

At Omnea, we embrace diversity. To build a product that’s loved by everyone, we’re best served by a team with all sorts of backgrounds, experiences, and perspectives. We encourage you to apply even if your experience doesn’t quite match the full job spec! And regardless of your race, religion, colour, gender, or anything else! If you think you could be a good fit for Omnea, please reach out.

A few things to note
We work Tuesdays, Wednesdays & Thursdays in-person at our offices right by Victoria station in London. At this early stage of our company life-cycle it’s important to us that we get this together-time. We’re commercial, ambitious and we don’t pretend otherwise! We’re actively seeking folks looking to make the most of a career-defining opportunity, with the hunger to be part of building something really impressive.

We sometimes use AI note-takers to help us transcribe interview notes, so we can be more present in your interview. If you’d like to opt out of us using automatic transcribers, please note this in the free text field in your application.
