Team Lead - Staff Software Engineer in London

Our Mission

At Omnea, we’re reinventing how enterprise businesses operate, starting with the most painful parts: procurement – where a single purchase can drag on for months, trigger 50+ emails, and pull in Finance, Legal, Security, and IT just to get something approved. We’ve raised $75M from Khosla Ventures, Insight Partners, and Accel to change that. Our AI‑native platform connects every person, step, and system so buying is fast, safe and efficient – one place to request, automated approvals and renewals, real‑time supplier risk and complete spend visibility. It’s a $7B+ untapped market, and our traction reflects the scale of the opportunity: we’ve 10x’d ARR to double‑digit millions in 18 months and are trusted by global enterprises like Spotify, MongoDB, Monzo and Albertsons. We’re now the 4th fastest growing startup in Europe.

Our team previously scaled Tessian (a cybersecurity tech backed by Sequoia, Balderton and Accel, acquired post‑Series C), and our team includes ex‑founder operators who have grown unicorns, shipped world‑class products and executed at the highest levels. You’ll work alongside leaders like Ben, Abs, Sabrina and Rebe.

What We’re Looking For

We’re seeking an exceptional, product‑focused Team Lead (Staff Software Engineer, L4) to join our engineering team and help guide Omnea through its next phase of rapid growth. Over the coming year, our team will double in size, our enterprise customer base will grow from around 100 to over 200, and our revenue will triple.

This Staff‑level role offers domain‑level impact, blending senior technical leadership with people‑management responsibilities. You’ll lead a team, mentor and develop engineers, and influence architecture and product outcomes across a wider domain, while staying hands‑on where it matters most.

You’ll be joining us at a pivotal moment. We’ve just closed a $50M Series B round led by 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 enterprise retention above 99% with clients like Spotify, Wise, Albertsons, Adecco and McAfee. Our small, high‑calibre team was built by interviewing over 10,000 candidates to hire our first 50 Omneans.

Now we’re scaling rapidly, building the category of AI Supplier Relationship Management. We’re seeking Staff‑level engineers who can lead teams or initiatives, influence technical direction across domains and help make procurement a strategic advantage.

You should be prepared for a pair‑programming interview stage in JavaScript or TypeScript, as if it were your primary language. This is a hands‑on leadership role – we expect Team Leaders to lead by example through code, technical decisions and delivery ownership. We’re hiring full‑stack engineers, so if your experience is mainly in frontend, backend, devops/platform or in a substantially different language (like Java), this role may not be the right fit.

We value skills over years of experience, but as guidance candidates typically have 8–10+ years of software engineering experience, including meaningful team or complex initiative leadership.

As a Staff Engineer at Omnea you’ll stay hands‑on, writing code and leading through technical execution and ownership – rather than through meetings or high‑level architectural discussions.

What Can You Expect in Our Tech Team?

• Join a skilled team. You’ll lead and collaborate with experienced full‑stack product engineers at one of Europe’s fastest‑growing early‑stage companies. As a Team Leader – Staff Engineer you’ll help your group of engineers succeed and raise the bar across the broader engineering organisation. Everyone on the team has a strong record of high performance at top tech companies and we hold ourselves to high standards for quality, ownership and impact.
• Direct product impact. You’ll directly influence product direction and execution – shaping the roadmap with Product and Design, defining project scopes, making architectural decisions and ensuring technical trade‑offs align with business and customer needs. At this level your influence typically spans multiple teams or systems, translating broad goals into effective high‑impact execution plans.
• Work with modern tech. Omnea is fully cloud‑native and serverless. Our core stack includes TypeScript, React & Material UI, Postgres, Hasura, and AWS serverless tools like Lambda, DynamoDB and EventBridge – all managed using AWS CDK & SST. We use Sentry, Lumigo and LogRocket for observability and GitHub Actions for CI/CD. As a Team Leader you’ll help define technical standards, guide best practices and ensure consistency across teams and systems.
• End‑to‑end ownership. You’ll own delivery outcomes from start to finish for a team or initiative – from discovery and technical design through deployment, monitoring and measuring customer impact. You’ll be responsible for quality, reliability and velocity while empowering engineers to take initiative and continuously improve how work is done.
• Continuous delivery. We embrace continuous delivery to keep our systems agile, safe and responsive. You’ll help your team ship small incremental updates to production several times a day, balancing speed with robustness, operational excellence and long‑term maintainability.
• Tackle scalability challenges. As Omnea grows from tens to hundreds of enterprise customers and expands into new product domains you’ll guide teams through major scalability challenges – evolving architecture, processes and technical standards while maintaining performance and reliability.
• Collaboration & autonomy. You’ll operate with significant autonomy, owning decisions within your domain and driving work forward. While embedded with a specific team your scope and influence are broader, working closely with other engineering leaders and cross‑functional partners to solve tough problems and align on strategy.
• Customers at the centre. Customer impact is at the core of everything we do. You’ll partner with Product, Sales and Customer teams to prioritise work based on customer feedback and issues, respond quickly to incidents and ensure delivery decisions maximise customer value across our product.

About You

• Experienced (usually 8–10+ years) building and leading the delivery of web apps, having designed and shipped end‑to‑end features (full‑stack, using TypeScript and ideally AWS).
• Impact‑focused. You’ve led teams or been responsible for delivery of critical systems and initiatives, working with top‑tier tools in AWS, IaC, observability and quality assessment. You’re eager to bring this expertise to a fast‑growing startup.
• A strong sense of best practices. You know what it takes to build reliable, well‑architected systems at scale and help set and champion high standards for code quality, testing, observability and operational excellence.
• Ready to deliver. You enjoy every aspect of building a product, are comfortable moving across the stack, love problem‑solving and think from first principles. You navigate ambiguity well and keep teams progressing.
• Ownership‑driven. You naturally gravitate towards complex engineering problems, enjoy setting direction, making prioritisation decisions, taking responsibility for delivery outcomes and unblocking teams when needed.
• A team builder and player. You’re excited to help boost team performance, whether by learning from others, explaining concepts, giving actionable feedback, mentoring engineers or representing engineering for a group.
• Comfortable with ambiguity. You thrive tackling problems that lack clear definitions or solutions, leading teams from vague objectives to focused execution with support from an experienced team alongside you.

Bonus Points

• Outstanding achievement in any area – academics, sports, work or otherwise. You’ve gone above and beyond expectations.
• A true passion for engineering. Whether it’s contributing to open‑source or building side‑projects, you pursue engineering out of genuine interest and enjoyment. You’re confident tackling ambiguity and producing 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!

A few things to note: We work Tuesdays, Wednesdays & Thursdays in‑person at our offices. 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; otherwise we will take your application as confirmation that you’re happy for us to use note‑takers (whether added to video calls or in the background).

We are proud to be recognised for both our culture and product, and we are just getting started. Join us as we grow!
