Company mission
One tool where you can: create strategy, build pipeline, track tenders and win bids. We help public sector teams move from disconnected workflows, mountains of data, unqualified opportunities and painful collaboration to a single, end-to-end process so you can focus on what really matters. Winning more contracts.
Role
Who you are
- The ideal candidate is a curious, analytical problem-solver with a passion for building and improving data systems that power real-world AI tools
- You understand that small, continuous improvements can dramatically enhance system performance, user experience, and product quality over time
- You’ll take a hands-on, proactive approach to developing algorithms, shaping AI-driven workflows, and streamlining processes that raise the bar for our data quality, coverage, and scalability
- A willingness to roll up your sleeves and get your hands dirty is essential—you won’t just plan solutions, you’ll build them, test them, and deliver outcomes that matter
- A bachelor’s degree in a technical or analytical field (e.g., STEM, economics, finance, etc.) is helpful, but not required
- At least two years of experience working hands-on with complex data analytics/science are a must-have
- Experience working in a fast-paced professional work environment where analytical thinking & rigorous organisation were required - e.g. high growing tech start-up, consulting (the list can be longer) - is highly valued
- Proven experience analysing, improving, or working with data in a real production environment - where your work directly informed business decisions and made a tangible impact on your organisation - is appreciated
- Likes to roll up your sleeves and get your hands dirty. “Our job isn’t done until the job is done”
- Ready to tackle the last mile when needed, and motivated by taking on challenges that stretch your personal capability
- Open to feedback and happy to collaborate. Aristotle said ‘the whole is greater than the sum of it’s parts’. That’s how we work!
- Unafraid to say, "I don't know the answer. But I have a few ideas on how we can find out"
- Analytical: you are able to search for patterns based on qualitative/quantitative insights and identify the causes for the pattern
- Highly organised: you have a high attention to detail and don’t let things fall through the cracks
- Data-driven and outcome-focused: you can track, interpret and evaluate outcomes to show impact
- Pragmatic: capable of focusing on the highest priorities and apply the 80/20 rule to achieve them (i.e. what 20% of the work will drive 80% of the impact?)
- Highly proficient English (written and spoken)
- Proficient in querying & manipulating data with SQL
- Hands-on-experience with Python for working with data
- Proven ability to analyse and interpret data and evidence to inform business decisions
- Nice to have: experience with data visualisation tools such as Metabase/Tableau etc
- Nice to have: working knowledge MS Office / equivalent business tools
- Most importantly, we're looking for curious, ambitious people who love to learn and want to be a part of building something special
What the job involves
- As part of our Data & Platform Team, you’ll lead the charge in pushing the boundary of what’s possible
- You’ll not only drive the breadth, depth, and quality of our data, but you’ll also harness AI to make it faster, smarter, and easier to use
- Your work will transform complex datasets into clear, actionable insights that empower our users to move quickly and make confident decisions
- This is about more than accuracy. It’s about impact. It’s about shaping how users experience our product — turning raw information into answers, signals, and next steps
- You’ll help us stay ahead by building data that’s not just reliable, but radically useful
- Your attention to detail, combined with a rigorous, scientific mindset, will help us measure, monitor, and continuously improve the systems that underpin our platform
- In this role, you’ll work at the heart of the Data & Platform Team and closely collaborate with our Product Lead, Engineers, Chief Product Officer (CPO), and Chief Technical Officer (CTO) to tackle the exciting challenge of scaling our AI capabilities, platform, and operations
- Together, you’ll ensure our AI-powered tools set the standard for quality, reliability, and impact—helping the product team deliver an exceptional, trusted platform for public sector insights
- Design and implement algorithms, models, and workflows to improve, enrich, and unify our core data assets. You’ll help us build smarter, more connected datasets that power our products
- Proactively explore and evaluate new data sources with a sharp focus on their potential product and market value
- You’ll assess how these datasets can strengthen our AI tools, improve user outcomes, and unlock new growth opportunities - balancing data quality, collection methods, and commercial impact
- Work with product managers, engineers, and the commercial team to ship, measure, and improve our AI-driven tools
- You’ll design evaluation frameworks, monitor system performance, and use insights to continuously improve outcomes through prompt engineering, system design, and optimisation
- Autonomously create, manage and improve efficiency of key processes to clean & enrich Stotles data by pushing towards automation and decreasing workload for engineers & dependence on external vendors
- Build and maintain structured processes to track Stotles data quality and coverage, using both qualitative and quantitative approaches
- Partner with teams across the business to ensure our data and AI capabilities support Stotles expansion in new geographies & verticals

Salary benchmarks
Our take
Stotles is aiming to break down the barriers to government contracting, so more firms can compete for public sector contracts, not just those with the right contacts.
They do this by using lots of government data to identify business opportunities in the public sector, and match them with the companies on their platform. The platform, which gets its name from Aristotle, enables suppliers to follow indicators, track potential contract renewals, monitor buyers, and monitor competitors.
The founders have been at the intersection of public and private sectors, at firms such as the World Economic Forum, Boston Consulting Group, and Bloomberg. They have experienced the pain of bidding for public work beforehand, which gave them the idea.

Diversity, Equity & Inclusion at Stotles
John Witt (CEO)
- ED&I is both important *and* urgent — in the short-term and long-term. It must not take a back seat.
- The phrase "Equality, Diversity, & Inclusion" (ED&I) refers to our initiative to create a well-rounded workforce and an environment where everyone has the opportunity to be the best version of themselves - no matter who we are, where we're from, or what we look like
- How we define equality: We view equality as the fairness of opportunity to contribute to the mission of Stotles - regardless of traits and characteristics of a person.
- How we define diversity: We view diversity as the traits and characteristics that make people unique. Gender, race, ethnicity, age, origin, religion, sexual orientation, and disability are some examples of how we are diverse at Stotles. We also consider diversity as differences in experiences and ways of thinking. Sometimes we can see things that make us diverse and sometimes we can't.
- We view inclusion as the behaviors, processes, systems, and norms that ensure all unique people feel welcome, and feel ownership of our mission, regardless of their background
