Role Overview
FlexAI is looking for a Senior Backend Engineer (Infrastructure & AI Platform) with deep Golang expertise to architect and build the core backend systems powering our next-generation AI compute and PaaS platform. This role sits at the intersection of distributed systems, cloud infrastructure, and AI platform engineering — enabling large-scale model training, inference, and orchestration across heterogeneous compute. This is not a traditional backend role; you will be building platform-grade systems that support AI runtimes, scheduling, resource orchestration, and multi-tenant cloud infrastructure.
As a Senior Backend Engineer, you'll drive backend architecture, scale platform services, and build high-performance infrastructure components that power AI workloads in production environments — influencing how the platform evolves from Beta to enterprise-grade deployment. Expect high ownership and technical autonomy in a research-driven, deep-tech setting — not SaaS CRUD apps.
What Makes This Role Unique at FlexAI
- Build backend systems powering next-gen AI compute infrastructure (not SaaS CRUD apps)
- Work on deeply technical problems across AI runtime, orchestration, and distributed infrastructure
- Direct influence on architecture as the platform scales from Beta to enterprise-grade deployment
- High ownership and technical autonomy in a research-driven, deep-tech environment
What You'll Do
Core Platform & Infrastructure Backend:
- Architect and develop high-performance Golang services for FlexAI's AI PaaS and infrastructure platform
- Build internal APIs powering model deployment, job scheduling, and compute lifecycle management
- Develop components interfacing with GPU/compute infrastructure and AI runtimes
Distributed Systems & Scalability:
- Design and scale microservices and event-driven systems for high-throughput AI workloads
- Optimize for low latency, high concurrency, and fault tolerance
- Implement service-to-service communication (gRP
