Frontend Engineer

NOTE: We do not offer visa sponsorship for this role. This role is strictly onsite, we do not offer remote work.

• Extensive React Native experience and clear ownership of mobile application architecture.

• Ability to define architectural patterns, module boundaries, shared abstractions, and engineering standards for a production mobile app.

• Strong understanding of how engineering breaks down across both frontend and backend, with the ability to work closely with backend and platform engineers on end-to-end system design.

• Experience building or operating mobile release infrastructure, including CI/CD, feature flagging, staged rollouts, crash monitoring, performance monitoring, and OTA update strategy.

• Experience building complex mobile products from the ground up, including major features and ideally an entire application.

• Strong security and compliance instincts, including secure handling of PHI, secure token storage, audit logging, and evaluating third-party dependencies in regulated environments.

• Experience working in heavily regulated industries such as digital health, financial services, or insurance.

• Comfort working in a greenfield startup environment with high ownership and ambiguity.

• Strong AI-tool fluency, with AI used as a core part of the engineering workflow to accelerate delivery without sacrificing quality.

Important fit notes:

• This role is best suited for a senior individual contributor who is still highly hands-on.

• Candidates with director, VP, architect, or people-manager profiles are generally less aligned unless they are still deeply hands-on in the code.

• This role requires someone who can lead technically while still building.

• This is an in-person role in the Boston/Cambridge area.
