Senior Engineer (Full Stack) at Hims & Hers

About the Role:

Hims & Hers is on a mission to empower people to live healthier lives. Our engineering teams play a critical role in achieving this by building the end-to-end product experience that helps patients understand and manage their health.

As a Senior Engineer, you will be a hands-on technical leader responsible for building and optimizing the patient-facing experiences and back-end services that power our platform. You will design, build, and iterate across the full stack, from modern, performant front-end interfaces to reliable back-end services and integrations with external partners, ensuring every feature is accurate, dependable, and delivers measurable impact for patients.

In this role, you will collaborate closely with product, design, operations, data, and other engineering teams to launch new features and workflows, improve the user experience, and refine the patient journey. By combining strong technical execution with a product-minded, data-informed approach, you will help more patients get meaningful value from our platform while improving the overall quality, reliability, and performance of the systems you own.

You Will:

• Lead the design and architecture of scalable, performant full-stack solutions that meet product requirements and enhance the patient experience.

• Provide technical guidance and mentorship to engineers on best practices, design patterns, and coding standards.

• Advocate for your team's technical priorities and ensure alignment within the broader engineering organization.

• Participate in product discovery sessions to assess feasibility, explore patient needs, and validate ideas through prototypes and experiments.

• Collaborate with UX/UI designers to create intuitive, engaging interfaces that help patients understand and act on their information, improving completion and engagement.

• Build and maintain reliable, well-monitored integrations with external partners and internal systems, with strong attention to data accuracy, privacy, and compliance.

• Work closely with other engineering teams to ensure seamless integration and communication across systems and services.

• Contribute to the team's technical vision by identifying strategic technologies and investments that improve scalability, reliability, and performance.

• Break down complex projects into clear, actionable tasks and lead execution to successful outcomes.

• Elevate engineering standards by improving workflows, processes, and tools to increase development velocity and quality.

• Analyze product, operational, and patient feedback metrics to identify optimization opportunities and drive continuous improvement.

• Create and maintain technical documentation for architecture, integrations, experiments, and development processes.

• Conduct code reviews and contribute to knowledge-sharing initiatives across the team.

• Model a culture of open communication, feedback, and continuous learning by coaching and supporting teammates at all levels.

You Have:

• 5+ years of professional experience building production web products with strong full-stack skills in React/Next.js and Node/TypeScript (or similar).

• Proven experience delivering scalable, high-quality web applications and services in a modern cloud environment.

• Experience building and operating third-party integrations and asynchronous, event-driven workflows (queues, webhooks, retries, idempotency) where correctness and reliability matter.

• Proficiency in front-end technologies (HTML, CSS, JavaScript, React, Next.js, GraphQL) and back-end technologies (Node.js, Nest.js, PostgresDB, Redis, Amazon SQS).

• Track record of shipping experiment-driven features that improved conversion, activation, or retention; comfortable with feature flag systems and experimentation platforms such as GrowthBook, Optimizely, or LaunchDarkly.

• Fluency in web performance optimization, accessibility, and modern UI engineering, with an eye for presenting complex information clearly and responsibly.

• Strong analytical and data skills, including event instrumentation, debugging analytics, and writing basic SQL or partnering with Analytics to define success metrics and guardrails.

• Deep product mindset: cares equally about UX, copy, and pacing as about architecture and APIs; approaches problems with iterative, testable solutions.

• Experience with Agile development methodologies and CI/CD pipelines, including automated unit and integration testing.

• Excellent problem-solving abilities and sound judgment in balancing speed, quality, and impact.

• Strong communication and collaboration skills with the ability to align partners, make trade-offs explicit, and drive initiatives from idea to execution.

• Highly organized, self-directed, and capable of prioritizing multiple projects to meet goals with minimal oversight.

• Bonus: experience in healthcare or another regulated domain (HIPAA, PHI handling), or with third-party partner integrations and industry data standards.
