Senior Staff / Staff Full-stack Engineer

About Us

We’re growing quickly across North America and partnering with retailers of all sizes to expand our reach.

If you’re passionate about creating real change for people and the planet, we’d love for you to join us. Your work here will directly contribute to a mission that helps families save money, reduces waste, and builds a more sustainable future.

What We're Looking For

We’re hiring a hands-on Tech Lead / Senior Staff Full-Stack Engineer to own and evolve core services and customer-facing experiences. You’ll be a TypeScript/JavaScript expert across our stack, including shipping backend services (Node.js + Go), modern React/Next.js frontends, and driving architecture, reliability, and developer productivity across the org. This is a player-coach role: you’ll write production code, lead cross-team architecture, mentor engineers, and work closely with Product and Business leaders.

What You'll Do

End-to-end ownership & delivery

• Own, design, build and operate critical services and customer experiences across backend and frontend.
• Ship high-impact features from design through production; own the full lifecycle (coding, testing, CI/CD, rollout, and runbooks).
• Troubleshoot complex production problems and lead reliability and performance improvements.

Architectural leadership

• Define and drive architecture for full-stack systems: APIs, data models, frontend architectures (React/Next.js SSR/ISR), and service boundaries.
• Simplify systems and reduce operational complexity while improving scalability and maintainability.
• Set standards for TypeScript usage, API design, testing, and observability.

Developer experience & platform

• Lead initiatives to improve developer velocity — CI/CD pipelines, local dev environments, monorepo / package strategies, infra-as-code, and tooling.
• Drive SLO/SLI thinking, observability (metrics, logs, tracing), and robust incident response / post-mortems.

People & cross-functional partnering

• Mentor and coach engineers across teams; provide technical reviews and career growth support.
• Partner closely with Product, Design and Business leaders to translate product goals into technical roadmaps and concrete plans.
• Influence cross-team priorities, identify technical risk, and balance tradeoffs between speed, quality and technical debt.

What You Bring

• 8+ years of professional software engineering experience with recent, hands-on full-stack development.
• Strong JavaScript & TypeScript expertise: you write idiomatic, type-safe, maintainable TS across backend and frontend.
• Extensive experience building and operating Node.js services (Express / Koa / Fastify or equivalent).
• Production experience with React and Next.js (server-side rendering, incremental/static regeneration, routing, data fetching).
• Experience with Go (Golang) for backend services or the ability to rapidly learn & lead Go services in production.
• Solid cloud experience (AWS/GCP/Azure), containers and orchestration (Docker, Kubernetes).
• Practical knowledge of CI/CD, automated testing, infra as code, and observability (metrics/logs/traces).
• Experience designing robust data models and working with relational and NoSQL databases at scale.
• Excellent communication, proven mentorship experience, and the ability to drive cross-team technical initiatives.

Nice to Have

• Experience with monorepos, TypeScript build tooling, and package management (pnpm/yarn/lerna).
• Familiarity with GraphQL, event streaming (Kafka), job orchestration (Airflow), or modern analytics platforms.
• Prior experience at consumer marketplaces, retail/grocery tech, logistics, or high-throughput systems.
• Experience leading large cross-team projects and defining org-level technical strategy.

What We Offer

• Competitive salary, equity, and comprehensive benefits.
• 100% remote work with flexibility and trust.
• Mission-driven work that reduces food waste and expands access to affordable food.
• A fast-growing, collaborative team with big ambitions.
• Real opportunities for career growth and professional development.
