Jobs Developers

About the role

We're looking for a software engineer with leadership experience to lead a small team building a product management ecosystem in the defense sector. This is not a purely managerial role — the lead continues writing code and contributing to development while coordinating the team, defining priorities, and owning delivery quality.

Responsibilities

• Develop and maintain internal deployment and product management tooling
• Build and maintain CI/CD pipelines (GitHub Actions)
• Own Docker-based build and deployment workflows
• Code reviews and technical quality across the team
• Team planning, backlog prioritization, cross-team sync
• Onboarding and mentoring team members

Requirements

• Strong Python: async, threads, concurrent programming
• Experience with Python web frameworks (FastAPI preferred)
• Deep understanding of Docker and containerization
• Linux: systemd, journald, containers, confident CLI usage
• Networking: HTTP(S), SSH, WebSocket
• Strong understanding of client-server architecture and API design
• Databases and ACID fundamentals
• Cloud or on-premise infrastructure experience

• English for technical communication

   

   

  Nice to Have

• Bare-metal / Raspberry Pi / embedded Linux (firmware flashing, secure boot)
• Information security fundamentals
• Python deployment optimization
• Experience with ArduPilot or other autopilot stacks

• Prior tech lead or mentoring experience

   

   

  What we expect from the lead

• Structured approach to planning — not purely ad hoc
• Clear cross-team communication: status, blockers, priorities
• Autonomy in technical decisions within the team's scope
• Readiness to grow ownership as the company scales

Position name: Senior React Native developer
Level: Senior Only

Soft skills requirements:

• Ability to work independently and collaboratively in a team environment.
• Excellent problem-solving skills and attention to detail.

Office/Remote: Remote
Project tasks:

• Pixel-perfect replication: Replicate the Lovable mobile site exactly. Every hex code, shadow, and frosted-glass effect must match the high-end web design 1:1. We do not compromise on design quality.
• AI-Streamlined Porting: Leverage Claude/LLMs to "convert" our React web logic and Supabase calls into high-performance React Native code to maintain startup speed.
• High-end Performance : Implement a vertical video feed using FlashList and the New Architecture to ensure 60-120fps scrolling with zero "jank."
