Backend Lead

About the Role :

We are seeking a Backend Lead who is passionate about building reliable, secure and scalable platforms that power web and mobile experiences. You will lead the backend engineering efforts across our product surface area — from public APIs and internal services to developer-facing tools and integrations. This role blends technical leadership and people leadership : you will supervise a small team of two backend engineers while remaining hands-on in architecture, implementation and delivery. You will collaborate closely with Product, your manager and other engineering leads / ICs and occasionally Design to deliver high-quality, maintainable systems that accelerate our roadmap.

What you'll do :

• Lead the end-to-end backend design, implementation and delivery across APIs, services and developer tools.
• Own architecture, reliability, performance, security and scalability for backend systems; collaborate with the Platform team on observability and infrastructure.

• Partner with Product, mobile / SDK, web and Platform teams to scope projects, sequence work and align milestones across teams.
• Design and drive the backend REST API for our core products (mobile app and mobile SDK), ensuring interfaces are consistent, well-documented and ergonomic for mobile, web and third‑party clients.
• Build and maintain internal systems and services (e.g., data processing, job / queue execution, admin and back-office tools).
• Plan and deliver integrations with third-party seller platforms (such as Shopify) and help shape language-specific API clients in major languages (e.g., TypeScript, Python, Go).
• Own our customer-facing API and docs site , continuously improving developer experience, documentation quality and onboarding.
• Serve as a technical point of contact with customers and partners for API / integration projects, including technical discovery, integration guidance, and escalation.
• Establish and evolve engineering standards , including code review practices, testing strategy, CI / CD workflows and release processes, with clear test coverage expectations.
• Share and adopt best practices in AI development tooling and workflows (e.g., prompt engineering, evaluation, retrieval, orchestration), collaborating with teams across the org and continuously learning to raise the bar.
• Mentor junior engineers through pairing, design feedback and career-supportive guidance.
• Uphold  security, privacy and compliance best practices; partner with the broader tech org on SOC 2 and GDPR initiatives; ensure high-quality releases with automation and comprehensive testing
