Hey! Thanks for taking the time to read through one of our open roles. We’re looking for an exceptional Senior Backend Engineer (Data) to join our Research & Development team and we hope this could be a match made in heaven.
Who is Peppy?
Our mission is to fix healthcare & wellbeing. We do this by supporting the employees of our global clients, including JP Morgan, Disney, Meta, Nvidia, Microsoft, Sony, Clifford Chance, Wells Fargo, Bloomberg, and over 200 others.
Having already revolutionised the employee benefits sector with our innovative clinical products – such as the world’s first menopause benefit – we are now building the world’s most advanced benefits management platform. Think of us as a “Deel for Benefits” – a rocket-ship opportunity with a mission that truly matters. The global benefits sector encompasses employer-funded pensions, critical illness insurance, private healthcare insurance, and many other categories. This is a trillion-dollar TAM with weak, incumbent competition and almost no AI-first startups stepping up to the challenge.
We are a Series B company with $56m in funding to date, operationally cashflow positive, and with secure access to additional capital for accelerated growth. Join us for the ride of your life.
What will a day in the life of our Senior Backend Engineer (Data) look like?

Apply your expertise in Python and other modern languages to deliver world-class applications as a leader, contributor, and mentor on an agile, cross-functional team
Act as a resource and champion for data across our application
Contribute effectively across our tech stack (primarily backend, data, ML) to routinely deliver user and business impact, with an appetite to expanding skills into frontend
Write clean, performant, and tested code, documented for the benefit of your peers and beyond
Participate in peer review and ensure high quality of deliverables via version control and CI/CD
Collaborate closely with product and design to define new features, functionality, and requirements by channelling your user empathy and personal experience to help craft a shared vision
Embody a growth mindset, working to advance and acquire skills with support from peers and leaders
Identify and act on opportunities to improve user happiness, impact the business, and simplify our technical surface area
Understand and support business functions beyond engineering, spanning our clinical, service delivery, sales, and marketing teams
Our dream Senior Backend Engineer (Data) will have:
Experience influencing and building impactful products from scratch, ideally for an early stage startup
A history of thriving in the ambiguity and uncertainty of nascent projects, and relishes the opportunity to shape the future
5+ years of professional experience building and architecting customer-facing Web Applications with a combination of Python and other backend languages like Java or Scala
Plenty of experience crunching data at scale, with expertise in data processing, data pipelines and data flows
Experience with Google Cloud (preferred) or AWS, plus Kubernetes and Kafka ideally
Familiarity with RESTful APIs (we use FastAPI), machine learning, and AI methods
Excellent communicator who can simplify complexity to share your work with the whole team and the wider company
First-hand knowledge what scale and quality look like in a larger technology company
Proven ability to learn, investigate, experiment, prototype, and iterate
A deep understanding of coding best practices and a dedication to creating efficient, scalable, and maintainable code
An insatiable desire to quickly release and iterate – you are happiest when the things you build go out in the wild
You may not check all of these boxes, and that’s totally fine! We strongly encourage excited candidates of all backgrounds to apply.
