About The Position:

Here’s how we’re different from outsourcing companies and freelance marketplaces:

  • Our engineers build a career through NUMI, not just a bunch of short jobs
  • We have 100% placement success rate for our engineers at great US-based startups, in as little as 2 weeks
  • We protect your interests - you’re always paid on time by us and won’t have to worry about any risks of doing business with unfamiliar foreign companies remotely
  • Our customers build the coolest products - from deep fintech infrastructure, to supply chain logistics, education platforms, developer collaboration tools, and ecommerce
  • Our customers are startup people just like you. They love tech, always read Hacker News, are up on the latest stacks and tools.
  • Our customers want to give you responsibility and autonomy, not just tickets. They love when you come with your own opinions on how to best build what they need!
  • Our engagements are long (6-18+ months), so you become part of the customer’s culture and team
  • We’ll do all the work to find you your next engagement before your current one ends
  • We aim to match you on one project at a time. Occasionally you may be working part time on two projects, but not often.

👨‍💻 About You:

  • You're an optimistic, senior engineer, ideally with at least 5 years' experience.
  • You have in-depth experience maintaining either Node.js and Reac.js projects (ideally both).
  • You have great communication skills (B2+ English strongly preferred).
  • You have your own Macbook.
  • You're excited to work with teammates from around the world, with a focus on US-based teams.
  • You're excited to take long term responsibility over early stage products, collaborating closely with founders and senior leadership at world-class startups.

Nice to have:

  • Automated testing workflows including CI/CD.
  • Collaborates with non-tech teammates.
  • Contributing to product roadmapping and prioritizing features.
  • Proficiency in frontend and backend, even if you prefer one over other.
  • Interest in producing good UI/UX products.
  • Experience as a "tech lead" or hiring / managing people.

💡 How it Works:

  • After an initial phone screen and review of your code, we'll arrive at terms for a trial period together
  • We'll search the Silicon Valley and YC community for startups looking for your talent, and match you with a good team and good project - we are very selective of what companies we work with.

🛠️ The Project:

  • A 4-person startup building AI-powered formula analysis tools for beauty and personal care manufacturers. The product allows beauty and personal care R&D teams to simulate lab experiments using the company’s AI models, and develop and test different formulas. Well-funded, backed by top-tier investors.
