Full Job Description

đź“‹ Description

  • • Senior Fullstack Engineer role focused on owning end-to-end development from API design to production UI within a modular monolith serving 150 tenants at 5,000 RPM.
  • • Day-to-day responsibilities include architecting features, writing and reviewing code, debugging production incidents, owning technical debt, and collaborating directly with product managers to resolve ambiguities in tickets.
  • • Onhires Inc. is undergoing a deliberate engineering transformation toward AI-native operations, where engineers use agentic tools as primary execution layers while maintaining architectural judgment and quality ownership.
  • • The role offers deep technical growth in high-scale systems, AI-augmented workflows, and leadership through mentorship and code review rigor in a flat, autonomous team structure.

🎯 Requirements

  • • 5-7+ years of commercial full-stack development experience
  • • Strong Python and Django/DRF skills with production Postgres experience under real load
  • • Production-level React and TypeScript - not side projects, not tutorials
  • • Proven ability to own a domain without micromanagement: architecture, code quality, test coverage, technical debt
  • • Self-directed work style with direct collaboration with product managers - no intermediary layers
  • • Experience with multi-tenant systems, high-volume data, or complex data pipelines
  • • Russian as primary working language; English at professional working level
  • • Active use of AI and agentic tools in your development workflow - or a demonstrated willingness and ability to adopt them rapidly

🏖️ Benefits

  • • A senior team with a flat structure - Engineering Managers and senior individual contributors. No unnecessary hierarchy. You are trusted to make decisions in your domain.
  • • Real autonomy - No fixed hours, no micromanagement. SLA on Slack is 24 hours. We care about outcomes, not presence.
  • • Unlimited paid time off - We trust you to manage your own time and energy responsibly.
  • • Offsites twice a year - Cyprus plus a rotating destination. In-person time matters; we invest in it.
  • • Learning and equipment budget - Conferences, courses, books, and hardware. If it makes you better at your craft, we support it.
  • • Stability - Very low turnover. Many engineers have been here 5-6 years. People stay because the work is good and the culture is real.
  • • Competitive compensation - Salary, stock options, and health coverage. You are fundamental to the company’s success and will be compensated accordingly.
  • • A company in transformation - You are joining during a deliberate shift to AI-native engineering. This is a chance to shape how a real engineering organization operates - not just watch it happen.
