Software Engineer (Internship)

Tunix.io is a software engineering company incorporated in London (TUNIX UK HOLDING LTD) with an engineering office in Tunis (TUNIX SUARL). Two delivery lanes:

• Engineering services — senior, full-remote engineers embedded in client teams (Python / Angular, B2B and B2G focus).
• ArmyAI — our on-prem AI agent platform for software delivery.

Small senior team, fully remote, biased to clarity and autonomy.

An AI assistant for triathlon / endurance coaches. A central intelligence layer that replaces the coach's manual, multi-platform workflow (reading TrainingPeaks, INSCYD reports, weather, then mentally synthesising signals from disconnected systems).

Multi-agent architecture: a lead orchestrator coordinates nine specialised agents (load, recovery, nutrition, technique, psychology, etc.). Universal principle: human-in-the-loop — the AI proposes, the coach validates. No autonomous action on athletes without coach approval.

V1 targets Phase 1 (single-domain agents); Phase 2 adds coordination protocols. Scientific basis: Dergaa et al. (2026), Biology of Sport.

• Frontend — React 18 + TypeScript, Tailwind, Recharts, Zustand + React Query. Read-only dashboard for the coach.
• Backend — Python 3.12 + FastAPI. Hosts the public API and the deterministic safety layer that validates every data-modifying action before execution.
• Agent runtime — Hermes Agent (Nous Research, MIT-licensed) self-hosted. Multi-model, persistent memory, natural-language cron scheduling.
• Datastore — Supabase (managed Postgres). No RAG / vector store in V1.
• Integrations — TrainingPeaks, Garmin Connect, INSCYD (CSV/JSON), OpenWeatherMap. Each integration exposed to Hermes via MCP tools, in its own adapter (hexagonal architecture).
• Hosting — personal VPS, TLS via Let's Encrypt, Hermes behind Tailscale VPN (egress-only, firewalled).

• Autonomy — full-remote demands personal rigour.
• Curiosity — the mission is open; we scope it with you based on what excites you.
• Solid coding fundamentals — one language mastered is enough; we pick up the rest together.
• Interest in AI multi-agent systems or B2B SaaS — both axes are open in this project.
• Bilingual EN + FR required — team and clients work in both languages.
