Job description

Full-Stack Engineer | AI/ML Start-up | Competitive Salary + Equity


We're partnering with a fast-growing technology start-up that's building intelligent, adaptive systems powered by real-time machine learning. They're looking for a talented Full-Stack Engineer to join their team and help scale their platform.


About Our Client


Our client has developed a sophisticated learning engine that processes live user behavior data to optimize digital experiences. They serve a growing base of mid-market clients and are expanding their platform capabilities. The company is well-funded, technically strong, and positioned for significant growth.


Why This Role Stands Out


This isn't your typical full-stack position. You'll work at the intersection of engineering and applied ML, building systems that process real-time data and deliver measurable impact. You'll have genuine ownership, ship meaningful features, and grow alongside a talented team solving complex technical challenges.


The Opportunity

  • Build and maintain APIs and data pipelines connecting real-time behavioral data to ML systems
  • Ship features to production that directly impact customer outcomes
  • Collaborate with cross-functional teams across engineering, product, and data
  • Contribute to development infrastructure including CI/CD, testing frameworks, and code quality
  • Debug production systems using modern observability tools (logs, metrics, traces)
  • Increase your technical ownership and responsibilities as you develop expertise

What You'll Need

  • Bachelor's degree in Computer Science, Engineering, Mathematics, or related field (or equivalent experience)
  • 1–5 years building and supporting production web applications
  • Strong backend or full-stack fundamentals: APIs, databases, asynchronous processing, testing
  • Production experience with Python and SQL
  • Familiarity with Git and CI/CD workflows
  • Excellent problem-solving and analytical skills
  • Interest in applied ML or LLM-based systems (production experience is a bonus, not required)

Nice to Have

  • Exposure to LLM-driven systems (prompt management, caching, streaming)
  • Experience with Docker; Kubernetes knowledge is a plus
  • Passion for exploring new technologies and continuous learning

Compensation & Benefits

  • Competitive base salary (commensurate with experience)
  • Meaningful equity stake in a growing start-up
  • Full health benefits: medical, dental, vision
  • 401(k) with employer matching
  • Remote work stipend
  • Generous PTO

Next Steps


If you're interested in working on challenging technical problems involving real-time data, ML systems, and production-scale infrastructure, we'd love to connect. We can share more details about the company, team, and tech stack in a confidential conversation.
