AI/Backend Developer

We’re looking for an AI/Backend Developer to help build the core engine behind our wellbeing and performance platform. Fast iteration, direct communication, zero bureaucracy — if you care about health, longevity, and pushing human limits, you’ll fit in.

You’ll build the core systems behind Agen’s wellbeing platform — fast, scalable, AI-powered. Your work will shape how people track their health, get intelligent recommendations, and improve daily performance.

We want someone who codes in Go because they love it, ships fast, and has real personal motivation in health, sports, medicine, or human performance.

• Build and scale high-performance backend services in Go.
• Create clean, reliable APIs (REST/gRPC) for app, robot, and internal systems.
• Design strong data models and queries in PostgreSQL.
• Work with MQTT for real-time data from wearables and devices.
• Integrate AI into real products — from API calls to fine-tuning and training Agen’s own models.
• Keep code clean, tested, and production-ready.
• Collaborate tightly with product, frontend, data, and hardware teams.

Must have:

• 3+ years building production systems.
• Strong Go skills (Gin, gRPC).
• Solid PostgreSQL experience.
• Hands-on work with MQTT or similar messaging.
• Experience with AI/ML APIs + interest/ability to fine-tune and train custom models.
• High ownership, fast execution, and direct communication style.
• Personal, deep interest in health, sports, performance, or wellbeing — non-negotiable.

Good to have:

• GCP/AWS + Docker/K8s.
• Kafka/RabbitMQ.
• Monitoring/observability tools.
• Personal healthtech or quantified-self projects.

• Competitive salary
• Flexible work arrangements
• Professional development
• Remote international team 
• Opportunity to deliver real results
