Senior Product Engineer - Pricing & Packaging

Requirements

• 5+ years of backend engineering experience shipping customer-facing or revenue-impacting systems
• Strong architectural instincts: you can design for correctness and scale across distributed, integrated systems, and make pragmatic tradeoffs to ship safely and fast
• High ownership orientation: you treat production health, pricing correctness, and data integrity as first-class concerns
• Clear technical communicator: you write crisp design docs, surface tradeoffs early, and keep stakeholders informed without being chased
• Comfortable in a high-reliability environment where a misconfigured price has immediate revenue impact
• Product-oriented mindset: you think beyond the code to understand how pricing decisions affect customers, revenue, and go-to-market strategy
• Resilient in fast-changing environments: you thrive when requirements shift, scope evolves, and ambiguity is the norm
• AI-first engineering practice: you use AI tools daily to ship faster, review better, and automate toil

Nice to Haves

• Prior experience in pricing, billing, payments or subscriptions domains
• Experience with pricing or billing platforms (Stripe Billing, Salesforce CPQ, or similar)
• Contributions to AI-powered engineering tooling: building plugins, skills, MCP integrations, or agentic workflows that make teams faster
• Comfort working across the full stack. The team owns customer-facing surfaces like paywalls and usage dashboards in React

What You'll Be Doing

• Design, build, and ship reliable systems across pricing configuration, packaging, trial mechanics, paywalls, and the integrations that connect them to billing and contract infrastructure.
• Own your work end-to-end: from technical design through deployment, observability, on-call, and incident response.
• Contribute to architectural decisions - identifying the right tradeoffs between near-term delivery and long-term platform health.
• Drive safe, well-managed change: system migrations, integrations, and modernisation efforts with robust rollout plans and data integrity guarantees.
• Build and iterate on AI-assisted engineering workflows - domain-aware CI checks, issue investigations, and automated triage tooling.
• Contribute to pricing integrity across systems - detecting and preventing drift between pricing configuration, billing state, Salesforce, and downstream financial reporting.
