Senior Software Engineer

About the Role

[Employer hidden — sign up to reveal] Digital is the team turning our world-class data into a product-led growth engine. A unified experience where customers can sign up, explore, and extract value on their own.

You'll work across two areas. Core is the platform backbone - identity, auth, entitlements, billing, and the infrastructure everything else depends on. Intelligence is the layer above the data - AI-powered insights, predictive models built on Databricks and Snowflake, anomaly detection, and agentic features.

This is a full-stack role. You'll own features from the data layer to the customer-facing interface. We care about UX as much as throughput, and we're AI-native - tooling is part of how we develop, not an afterthought.

What You'll Be Doing

• Own features end-to-end - from problem-shaping with Product and Design through implementation, testing, production releases and future enhancements
• Build customer-facing experiences and the backend systems and data models behind them
• Evolve platform architecture across Core and Intelligence for scalability, reliability, and sustainability
• Lead technical decisions and engineering strategy, balancing innovation with pragmatism
• Build core platform capabilities: auth, entitlements, billing integrations, and usage management
• Integrate AI models, data pipelines, and event-driven systems on Databricks and Snowflake into the Intelligence layer
• Maintain the quality bar through code reviews, automated testing, observability, and CI/CD
• Support junior and mid-level engineers and help them grow

What We're Looking For

• Extensive full-stack experience building and shipping production-grade systems
• Strong front-end skills (React, TypeScript, or equivalent) with genuine care for great web interfaces
• A builder’s mindset. You understand the who and the why, and you own what ships.
• Strong C# (or comparable OO language) and confidence across the full stack
• Solid system-design knowledge (scalability, reliability, security) and the ability to defend architectural trade-offs
• Experience with CI/CD pipelines, automated testing strategies, and DevOps practices
• Familiarity with relational and NoSQL databases, and comfort working with data at scale
• Demonstrated ability to mentor engineers and lead - not just contribute to - technical decisions
• Clear communicator who works directly with Product and Design and can shape problems as well as solve them
• AI-native in how you develop - you use AI tooling daily and expect the same from your team

It Would Be Great If You Also Had

• Experience with Databricks or Snowflake, particularly in analytical or data-intensive contexts
• Familiarity with AI/ML in production: model serving, prompt pipelines, or agentic patterns
• Experience with consumption-based and subscription billing
• Experience with self-serve billing platform integrations
• Exposure to aviation, travel, or data-as-a-service businesses
• Experience standing up or significantly improving engineering foundations for a new product or team
• A portfolio showing you've raised the bar on UX, performance, or product craft

We Will Offer You

• A progressive, non-hierarchical culture where innovation drives everything we build
• Flexible working arrangements that allow remote work or office attendance
• An attractive compensation and benefits package, including private health insurance, a company bonus scheme and enhanced pension scheme
• 25 days holiday plus bank holidays, volunteering days and additional day off during your birthday month
• Octopus EV salary sacrifice scheme
• Work remotely anywhere in the world for up to 1 month per year
• Annual learning and development budget
