Concentrate provides one OpenAI-compatible API to access, route, and manage models across leading AI providers and open-source models through a single endpoint. We help teams save time, lower token spend with credits back from our bulk purchasing power, improve reliability, and avoid vendor lock-in.

Supported by top-tier VCs. This is a remote role.

You'll work directly with customers to solve LLM infrastructure and deployment problems, while also building the product and platform capabilities that make those solutions scalable. This is a highly hands-on role for someone who is technical, pragmatic, and excited to operate across customer work, engineering, and product at an early-stage AI API company.

What You'll Do

• Work closely with customers to understand LLM deployment needs and solve technical problems in production
• Debug issues end to end across application behavior, AI API integrations, infrastructure, and model and provider performance across OpenAI, Anthropic, Gemini, and open source models
• Build product features, internal tools, and platform improvements based on patterns you see in the field
• Improve multi-provider routing, LLM reliability, AI observability, latency, and token cost efficiency across multiple LLM providers
• Help customers reduce AI infrastructure costs, navigate rate limits, and architect for provider failover and redundancy
• Partner closely with founders on customer deployments, product direction, and technical strategy

What We're Looking For

• Strong technical ability and high ownership
• Strong debugging instincts across backend systems, AI APIs, infrastructure, and customer environments
• Experience working with or around LLM APIs, model routing, or AI spend management is a strong plus
• Comfort working directly with customers and operating in ambiguity
• Startup experience or experience in fast-moving, high-ownership environments
• Experience with some of: Python, TypeScript/Node.js, PostgreSQL, Redis, AWS, Docker, Kubernetes, Terraform, and CI/CD workflows
• Clear written and verbal communication skills
• Fluent English required

Bonus

• Experience with LLM gateways, AI gateway architecture, or enterprise AI infrastructure
• Familiarity with zero data retention, PII redaction, or AI compliance requirements
• Experience with LLM cost optimization, token spend analysis, or provider discount structures
• Experience in forward deployed, solutions, or customer-facing technical roles
• Early startup experience
• Interest in growing into broader technical leadership over time

Salary Range: $200K-$300K cash compensation + strong equity
