Senior Backend Engineer, Elliptic

• Have 5+ years of experience as a backend or full-stack engineer
• Are strong in TypeScript/Node.js (or JavaScript with willingness to adopt TypeScript)
• Are comfortable with PostgreSQL — schema design, query optimisation, understanding trade-offs
• Have built integrations between systems — REST APIs, webhooks, sync jobs, handling failures gracefully
• Find business processes genuinely interesting — pricing models, subscription logic, usage tracking, commercial metrics
• Care about code quality, but also about shipping things that work
• Want your work to have visible business impact, not disappear into a backlog

Desirable

• Great commercial operations are powered by great technical infrastructure
• At Elliptic, we're not just connecting systems — we're building the backend services, integrations, and internal applications that enable our revenue teams to operate at scale
• You'll be the engineer behind our commercial technology stack, building the backend systems that pull together product usage, contracts, subscriptions, and customer data — powering everything from billing accuracy to renewal forecasting to customer health scoring
• This isn't just systems integration — you're building the technical infrastructure that enables Elliptic to understand and act on commercial reality across the entire customer lifecycle, from first touch to renewal and expansion
• Build the foundation our revenue organisation runs on
• You'll define how we structure, store, and access commercial data — creating the backend systems that enable data-driven decisions, accurate billing, and eventually AI-powered automation
• This role sits at the intersection of backend engineering, commercial systems, and revenue operations
• You'll translate business requirements from across marketing, sales, and customer success into well-designed schemas, reliable integrations, and internal tools that make the business work
• Problems You'll Solve:
• "A customer is using 3x their contracted volume but nobody noticed until renewal."
• You'll build the systems that track usage against contracts in real time, so commercial teams can act before it's a difficult conversation
• "We can't tell if this customer is healthy or about to churn."
• You'll connect product activity, support tickets, and commercial data into a unified view that actually means something
• "Updating a contract takes three teams and a spreadsheet."
• You'll build internal tools that let Ops teams manage commercial data directly, with proper validation and audit trails
• "Our CRM says one thing, our billing system says another."
• You'll design the integrations and data models that make our systems agree on reality
