Principal Software Engineer

Coworker AI

Principal Software Engineer
About the job

We need a talented, ambitious, hard-working principal software engineer with 10+ years of experience who can help us build the foundation for the next era of work. We need someone who wants to change how the world works, one company at a time.

You are that person.

You are a deeply technical full stack software developer who ships high-quality code as the strong majority of your time, while also providing thought leadership and mentorship to the team. You are obsessed with making customers happy, and will do whatever it takes to make it happen. You are autonomous and happy to take on big, ambiguous problems at a fast-growing startup.

You know when to push and when to rest; you model sustainable high performance for the team. But you (like us!) are more than your code and your hard work! You love building a culture where people love to work but believe in putting people first while having a huge amount of fun while you do your job.

You will burn tokens like the VC money will never stop flowing.

What you will do in the role
  • Ship code daily. Hands-on development is the strong majority of your time
  • Own the architecture and technical roadmap for a core domain; dive deep into the hardest problems when needed
  • Mentor senior and staff engineers; be the technical escalation point for the toughest challenges in your domain
  • Be a thought leader in the enterprise AI space
  • Represent Coworker externally through talks, blog posts, or open-source contributions
  • Guide early Coworker technical architecture decisions that will resonate throughout the global economy for years to come
  • Establish the Coworker engineering culture - live the mission and set a standard
  • Help the product team craft the team vision, strategy, and roadmap while proposing innovative solutions, as well as understanding technical limitations
  • Drive cross-org technical initiatives with measurable business impact
  • Drive incident response and post-mortems for company-critical issues; ensure we learn systemically from failures
  • Hire and interview for senior+ roles; raise the bar for engineering talent across the org
  • Have an inordinate amount of fun
  • Push the frontier of what's possible with Enterprise AI
Position Qualifications
  • Bachelor's and/or master's degree (Computer Science preferred)
  • 10+ years of professional development experience
  • Experience and desire to own new products from zero to one, from system design to implementation to deployment
  • Strong communication and collaboration skills
  • Experience and comfort using AI aggressively to improve velocity with looping, reinforcement
  • Any languages are fine, we primarily use GoLang, Typescript, and Python
  • Deep expertise in at least two of: distributed systems, data pipelines, AI/ML infrastructure, security, or frontend architecture at scale
  • Proven ability to lead without direct authority; influenced technical direction across team boundaries
  • Experience defining SLAs, SLOs, and running production systems at scale with strong operational discipline
Perks
  • Unlimited paid time off
  • Medical, dental, and vision
  • Early and generous employee stock option plan
  • $100 monthly health and wellness benefit
  • 401(k) plan
  • Paid family leave
  • Apple products for work
  • Daily tetris matches
Drop us a line!

We encourage you to drop us a line even if you feel over- or under-qualified. We want to find the best people to help us build Coworker no matter who they are. We have a lot of different areas of responsibility and we are always happy to brainstorm with you about what would be the best fit.


Coworker.ai is an equal opportunity employer. We believe everyone should feel great about being their authentic selves at Coworker-this is the only way to do our best work! We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status. We believe that great employees come from diverse backgrounds.
