About Us:

Function was founded with a singular focus: empower you to live 100 healthy years. We’re doing that by using the best available technology to make sure people don’t suffer or die a preventable death. Function has been recognized as one ofΒ Fast Company’s Most Innovative Companies of 2024, and is venture-backed byΒ Andreessen Horowitz (a16z). Hundreds of thousands of members have joined Function to take control of their health. We are growing our team and seeking out world-class talent that deeply believes in our mission to positively impact global health, has a relentless bias toward action and a growth mindset. Function fosters a collaborative and dynamic environment, where every day we are building the future.

Role:

In this role, you’ll not only leverage your expertise in TypeScript, React, Redux, and Sagas, but also guide frontend architectural decisions, influence cross-functional technical strategy, and mentor other engineers. You’ll partner with backend engineers to ensure seamless integration and occasionally dive into backend systems when necessary.
We’re looking for someone who’s not only proficient in our frontend stack but also understands the broader technical architecture and the business impact of their work. If you thrive in a fast-paced startup environment, are detail-oriented, and can adapt to shifting priorities while maintaining high-quality standards, this role is for you.

Key Responsibilities:

  • Develop and Maintain Frontend Codebase: Write clean, performant, and scalable code using TypeScript, React, Redux, and Sagas, ensuring maintainability and future scalability of the codebase.
  • Architectural Integration: Understand and contribute to the overall technical architecture, ensuring seamless integration between front-end components and backend services (APIs, databases, etc.).
  • UI Precision: Translate Figma designs into precise code, accounting for various UI states (hover, active, loading), cross-browser compatibility, and different modes (dark/light, mobile/desktop).
  • Performance Optimization: Implement performance optimization techniques to maintain a fast and responsive user interface, even as the codebase grows.
  • Code Reviews and Standards: Establish and enforce coding standards, perform thorough code reviews, and advocate for engineering excellence across the team.
  • Cross-Functional Collaboration: Work closely with product managers, designers, and backend engineers, contributing to discussions and proactively addressing potential issues.
  • Mentorship and Leadership: Provide technical mentorship, lead design reviews, and help establish best practices for the frontend team.
    • Architectural Leadership: Define and communicate frontend architecture that aligns with long-term business and technical goals.
    • Technical Leadership: Provide technical direction and mentorship to engineers, ensuring alignment with best practices and long-term architectural vision.
  • System Design and Architecture: Lead the design of complex systems and features, making decisions that balance scalability, maintainability, and business needs.
  • Incident Response and Reliability: Drive initiatives for monitoring, logging, and alerting to ensure reliability, security, and high availability of the frontend systems.
  • Scaling Practices: Anticipate and plan for growth in traffic, data, and team size by defining scalable engineering processes and systems.

Qualifications/Skills:

  • Expertise: 10+ years in Frontend development
  • Technical Proficiency: Strong proficiency in frontend technologies, particularly TypeScript, React, Redux, and Sagas. Familiarity with other modern frameworks/libraries is a plus.
  • Code Quality: Demonstrated ability to write clean, scalable, and maintainable code, with a focus on future scalability and performance.
  • Architectural Understanding: In-depth understanding of how frontend components integrate with backend services and the overall technical architecture.
  • Security Awareness: Strong understanding of security best practices, particularly in handling sensitive data and securing frontend applications.
  • Performance Optimization: Experience with performance optimization techniques to keep the frontend fast and responsive as the codebase scales.
  • UI/UX Precision: High attention to detail in matching code output to design specs, considering all UI states and cross-browser/device compatibility.
  • Business Acumen: Ability to grasp and align with the company’s business logic and strategic goals, contributing to UX and product discussions.
  • Communication and Independence: Excellent communication skills, with the ability to work proactively, independently, and asynchronously in a fully remote environment.
  • Adaptability: Comfortable with context switching and adjusting to changes in priority, particularly in a fast-paced startup environment.
  • Leadership Experience: Proven experience leading technical initiatives, mentoring engineers, and shaping engineering culture.
  • Strategic Thinking: Ability to think beyond immediate features and make decisions that align with long-term technical and business strategy.
  • Deep Problem-Solving: Expertise in debugging and resolving complex, high-impact issues across the stack.
  • Tooling and Automation: Experience building developer tooling and CI/CD workflows that enhance team productivity.

To be a strong fit you also need:

  • Bias Toward Action: Demonstrated ability to take initiative, make decisions under uncertainty, and move projects forward even in the face of ambiguity. We value individuals who are self-starters and ready to act on opportunities and challenges alike.
  • Entrepreneurial Spirit: Strong adaptability to changing business needs with a knack for building and optimizing processes. Your entrepreneurial mindset will be crucial in navigating the dynamic landscape of our industry, ensuring our platform remains competitive and responsive to user needs.
  • Communication: Excellent communication skills, capable of explaining complex technical concepts to non-technical stakeholders. Effective communication is vital for cross-functional collaboration and ensuring alignment across our organization.
  • Remote Work Adaptability: Comfort with remote work environments, demonstrating the ability to stay productive and connected with the team irrespective of physical location.
  • Continuous Improvement: A willingness to question assumptions and a commitment to continuous improvement. Your openness to feedback and dedication to personal and professional growth will contribute significantly to our collective success.

Your dedication to these responsibilities will directly contribute to the success of our platform and the satisfaction of our users. We are looking for a proactive, skilled, and forward-thinking individual to join our team and help shape the future of our services.
