Job description

Picnic is reinventing lunch at work. We partner with top local restaurants and batch hundreds of orders at a time to deliver high-quality, individually packaged meals—without fees or tips. The result is a seamless, affordable, and joyful experience for employees, and a more sustainable model for restaurants.

We recently launched, and early signals have been exceptionally strong. Picnic has been adopted organically by companies across a wide range of industries, with customers discovering and advocating for the product before any marketing. Since launch, we’ve grown incredibly fast and are now entering the 10 → 100 scale phase as we expand across major North American markets.

Picnic owns the full stack that powers workplace food delivery: kitchens, courier operations, routing and batching systems, operations tooling, and client applications. This vertical ownership allows us to tightly integrate software, logistics, and operations to deliver reliable, cost-efficient service at scale.

About the role

We’re looking for a Senior or Staff Frontend Engineer to help build and scale Picnic’s real-time logistics and operations platforms. This role is ideal for someone who thrives in ambiguity, enjoys working on complex, high-performance systems, and wants to shape frontend architecture that directly powers real-world operations.

You’ll work across web and mobile surfaces, partner closely with backend and operations teams, and play a key role in defining how we build, ship, and scale frontend systems at Picnic.

What you’ll do

• Design and build high-performance React applications powered by WebSockets, SSE, and GraphQL subscriptions.
• Contribute to and shape our courier mobile apps built in React Native.
• Lead technical design for complex features and systems, from initial architecture through production rollout.
• Own projects end-to-end, driving execution, technical decisions, and cross-functional alignment.
• Improve frontend reliability, latency, and scalability in a real-time, high-throughput environment.
• Lead debugging, incident response, and performance investigations for frontend systems.
• Mentor and coach engineers, raising the bar for frontend engineering across the team.

What we’re looking for

• 3+ years of experience in software engineering, with deep frontend expertise.
• Strong experience with TypeScript and modern web application development.
• Solid understanding of client networking, async programming, performance optimization, caching, and client-side state management.
• Experience integrating with GraphQL and REST APIs.
• Proven ability to lead technical initiatives and influence architecture and best practices.
• Experience mentoring junior engineers and supporting team growth.
• Comfort working outside your immediate comfort zone and adapting as the product and team evolve.

Preferred Qualifications

• Experience building or operating delivery, logistics, or real-time systems at scale.
• Full-stack experience and an understanding of backend tradeoffs and system design.
• Track record of improving developer productivity through tooling, patterns, or process improvements.
• Familiarity with modern frontend architecture best practices, including performance, security, and usability.
• Massive market opportunity: Online food delivery continues to grow rapidly, creating room for durable, category-defining companies.
• Real impact: You’ll help reshape how restaurants succeed in delivery while improving everyday experiences for thousands of workers.
• Ownership and influence: Frontend is core to Picnic’s operations—your work directly impacts couriers, operators, and customers.
• Strong engineering culture: You’ll collaborate closely with experienced engineers and leaders who care deeply about craft, impact, and growth.
