ABOUT US

We are Playbook, a leading creator platform for fitness, health, and wellness. Our mission is to help fitness creators build sustainable businesses, while enabling hundreds of thousands of users to live healthier lives.

We are a fast-growing company in the fitness tech space, operating as a remote-first, product-driven team that values ownership, direct communication, and a strong growth mindset. We believe in "drivers, not passengers" - everyone is encouraged to take responsibility, think proactively, and act like an owner.

ROLE OVERVIEW

We're looking for a Senior Product Engineer (TypeScript) to join our remote engineering team. You'll work on meaningful, user-facing product features across the stack - building reliable backend services and polished web and mobile experiences.

Our product spans three surfaces sharing one language: a ReactJS web app, a Node.js backend (GraphQL), and a React Native mobile app - TypeScript everywhere. We don't expect you to be a deep expert in all three. We're looking for a T-shaped engineer: deep senior expertise in one of these areas, working proficiency in the others, and genuine willingness to ship across the whole stack. Whether your strongest suit is frontend, backend, or mobile matters less than the profile itself: deep in one area, capable across all three.

You'll collaborate closely with Product and Design to deliver solutions aligned with real customer needs. This role is best suited for a senior individual contributor who enjoys hands-on development, understands that good architecture starts with clear contracts, and thrives on solving complex problems in a fast-moving startup environment.

RESPONSIBILITIES

* Design and implement new features across the stack (Node.js, ReactJS, and React Native), with a strong focus on usability, clarity, and real user value, shaping APIs and GraphQL contracts as part of the feature design process.

* Spend the majority of your time in your area of deep expertise, while regularly contributing across the web app, the backend, and the mobile app - picking up features, smaller tasks, and code reviews wherever they're needed.

* Build and evolve backend services and APIs (REST and GraphQL) that power our platform. Focus on reliability, maintainability, and clean integrations with frontend applications and third-party services.

* Work closely with Product Managers and Designers to translate requirements into practical, well-scoped technical solutions.

* Contribute to Engineering Requirement Documents (ERDs) that define data models, API contracts, and integration points before implementation begins.

* Write clean, readable, and well-tested code. Participate in code reviews and contribute to shared standards around quality, testing, and maintainability. Improve existing systems where it provides clear product or developer value.

* Take responsibility for the features you build. Identify issues or gaps, propose improvements, and iterate based on feedback. You're comfortable working with some ambiguity and adapting as requirements evolve.

* Break down product requirements into data models, GraphQL types, and component structure before writing implementation code.

REQUIREMENTS

Core (everyone):

* 5+ years of professional software development experience with TypeScript as your primary language. Advanced TS proficiency - complex types, generics, conditional types, and using the type system to enforce contracts and model domain logic across the stack.

* Proven experience shipping production applications end-to-end and owning features from design through release.

* Active daily use of AI coding assistants (Claude Code, Codex, OpenCode, or similar) for development, debugging, and problem-solving. We expect engineers to leverage these tools to ship faster and work through complex problems.

* Strong communication skills in English. Comfortable working in a remote, cross-timezone team and collaborating asynchronously.

Deep senior expertise in at least ONE of:

* Web (ReactJS): modern frontend patterns, performance, component architecture, responsive and user-friendly interfaces with attention to detail. Familiarity with TailwindCSS or similar styling frameworks.

* Backend (Node.js): GraphQL schema design, resolvers, dataloaders, and API structure for maintainability. Strong experience with relational databases (PostgreSQL preferred), including schema design, query optimization, and reasoning about data consistency and performance.

* Mobile (React Native): shipping and maintaining production RN apps, native module integration, app store release cycles, mobile performance, and offline patterns.

Working proficiency in the other two - you can read, extend, and review code there today, and you're motivated to grow toward senior level across all three. If you've only ever worked in one lane and want to stay there, this role isn't a fit.

NICE TO HAVE

* Experience with Node.js frameworks: Next.js, NestJS

* Familiarity with Expo / EAS or native iOS/Android tooling

* Familiarity with CI/CD pipelines, infrastructure as code, and improving observability and logging

* Familiarity with AWS. We use services like Lambda, Step Functions, SNS/SQS, DynamoDB, and ECS - hands-on experience with some of these is a plus.

* Experience building or integrating payment and subscription flows (e.g. Stripe, billing systems, in-app purchases).

* Experience working in a startup or fast-growing product company.

WHAT WE OFFER

* Your work will directly affect creators and users on the platform. You'll work on features that ship quickly and matter.

* We offer a wide compensation range to reflect different seniority profiles within this role, including the breadth of your cross-stack skills - engineers who are senior across multiple surfaces sit higher in the range.

* Equity options

* 100% remote with flexible working hours and async-friendly culture. Collaboration across Europe and the US East Coast.

* A collaborative team that values ownership, open communication, and autonomy over micromanagement.

* Yearly team retreats focused on connection, alignment, and building strong team relationships.

* Paid Time Off
