Job description

hOS is an early-stage technology company founded in 2021 by several DataRobot alumni and former executives, including founder and former CEO Jeremy Achin. The company is operating in stealth-mode developing scalable technologies and AI-driven products that will make significant positive change in the world.


About the role

In this role, you will engineer and develop the backend that will serve 10s of millions of users. There is no legacy codebase which means you don't need to suffer from old poorly-written code, you need to write clean code from scratch. As one of the first engineers in the company, you will be responsible for ensuring the code style is implemented consistently across the codebase right from the start. Keeping the code modular and easy to read is one of the top priorities. At the same time, as a growing start-up, we are moving at a fast pace, so you need to be agile and focus on delivering software that does the job first and then improve it step by step. You will work directly with the founding team.

Responsibilities

  • Develop backend in Python (the first priority is a mobile app backend)

  • Deliver efficient code that does the job first and iteratively improve it later

  • Adhere to code guidelines and keep co-workers accountable for it as well

  • Ship code that is easy to read, maintain and debug

  • Be on top of all most recent code practices, libraries and frameworks and push the team to use better tools

  • Conduct thoughtful code reviews for your team members

Basic qualifications

  • 3+ years of Python experience, 5+ years of software engineering experience

  • Proficiency in unit/integration testing

  • Good understanding of how to implement useful logging

  • Understanding of code complexity measurements (O(n)) and why it is important

  • The skill of documenting your own code (writing useful comments)

  • You iterate quickly with short feedback loops

  • You're comfortable with change and ambiguity and thrive working autonomously

  • English level - Intermediate or higher

  • Experienced using self-improvement apps (habit trackers, time management tools, fitness trackers, etc.)

Preferred qualifications

  • Previous experience working at high growth start-ups

  • Previous experience working with distributed teams in different time zones

  • Previous experience building backends to support millions of users


We are an equal opportunity employer and select individuals best matched for the job based upon job-related qualifications regardless of race, religion, color, creed, sex, sexual orientation, age, ancestry, national origin, gender identity, genetic information, disability, pregnancy, veteran or military status or any other status or characteristic protected by law.
