Maximus (https://www.maximustribe.com/) is a mission-driven consumer performance medicine telehealth company that provides men and women with content, community, and clinical support to optimize their health, wellness, and hormones. Maximus has achieved profitability, 8-figure ARR, and is doubling year over year - with a strong cash position. We have raised $15M from top Silicon Valley VCs such as Founders Fund and 8VC as well as leading angel investors/operators from companies like Bulletproof, Tinder, Coinbase, Daily Stoic, & Shopify.

Maximus is building an advanced telemedicine platform to help men improve their mental and physical health. We iterate on our product rapidly and safely by applying continuous integration and code quality measurements, as well as TDD and pair programming when appropriate. We work collaboratively, emphasizing the productivity of the team first. We aim to deliver a robust, reliable system by using pragmatic, tried-and-true technologies. We hone our craft as engineers by applying advanced functional, data-oriented techniques that are appropriate to the problem.

Please note: Culture is key at Maximus, so we get to know candidates holistically through our questionnaire. You will receive an invite in a separate email upon submitting an application. Please fill it out as honestly and intuitively as possible since it is designed to detect exaggeration, which will cause your application to be automatically rejected. The questionnaire is optional to submit now with your application, but candidates that do so will get strongly prioritized. Note, we do not have access to individual questions’ answers/choices.

What we are looking for (Key Responsibilities):

  • Write and ship high quality code. Contribute across the codebase to complete entire features and changes with support from the rest of the team. Continuously invest in demonstrable quality and reliability of the system via unit tests, automated integration tests, TDD and refactoring. Keep data management and security in mind at all times to protect customer privacy.

  • Contribute to a continuously improving engineering organization. Identify software quality, performance, and operational issues, including impediments to team-wide efficiency and work constructively with the team to address them. Define and improve our internal engineering standards and processes and exert positive influence on the objectives and tactics taken by the team.

  • Contribute actively to product iteration and development to ensure the company delivers a compelling experience to its customers. Generate ideas and assess the associated options and tradeoffs for how they impact the growth of the business and customer experience. Work across functional teams (engineering, marketing, product, etc.) to translate business and product ideas into software designs and releases. Product & Project Management skills and experience are a plus.

  • Familiarity with or interest in Event Sourcing and other immutability / functional-programming patterns.

  • TDD experience is a plus.

Qualities:

  • A dedication to keeping things simple and pragmatic.

  • Attitude of shared ownership of the system, frequent integration. Collaborates proactively, in service of the shared highest priority.

  • Strong communication and teamwork skills: Proven ability to build strong relationships with technical and non-technical members of the team to solve challenging technical and business problems.

  • Relentlessly Resourceful (http://www.paulgraham.com/relres.html): highly proactive, does not quit, and finds innovative solutions with little guidance. Bias for action and ability to thrive in an ambiguous environment with a high degree of autonomy.

  • Passion for Men’s Health & Development: interest in helping men develop a healthy masculinity. Demonstrates personal dedication and interest in health optimization (e.g. diet, exercise, sleep, focus, and relationships).
