[Hiring] Software Engineer - AI @Synthio Labs

Role Description

Synthio is looking for a hands-on Software Engineer who enjoys building end-to-end systems and shipping production-grade products. This role sits at the intersection of backend engineering, AI systems, and infrastructure. You’ll work on LLM-powered and voice-enabled applications, integrate external APIs, and own services from design through deployment and operation.

You’ll join a small, fast-moving team building real-world software for healthcare and pharma, where reliability, performance, and correctness are non-negotiable. We value engineers who take ownership, move quickly, and are comfortable operating across the stack.

• Build and maintain backend services that power AI- and LLM-driven products
• Design and implement APIs, data flows, and service integrations
• Productionize LLM-based workflows (prompting, retrieval, orchestration, evaluations)
• Deploy and operate services with a focus on low latency, high availability, and robustness
• Design and manage infrastructure (containerization, cloud services, CI/CD)
• Work on voice-enabled systems (STT/TTS, streaming APIs) as part of end-user experiences
• Monitor, debug, and optimize systems for performance, reliability, and cost
• Collaborate closely with founders and product stakeholders to turn ambiguous requirements into scalable software
• Own features and services end-to-end, from initial design to production support

Qualifications

• 1–3+ years of experience in software engineering or backend-focused roles
• Strong proficiency in Python
• Experience designing and building APIs and backend systems
• Hands-on experience working with LLM APIs (OpenAI, Anthropic, or similar)
• Comfort with cloud infrastructure and DevOps fundamentals (Docker, AWS ECS/EKS/Lambda, observability, basic security)
• Interest in AI-powered systems, including voice and conversational interfaces
• Solid systems and architecture thinking, with a pragmatic approach to tradeoffs
• Ability to work with incomplete specs and make sound engineering decisions independently

Benefits

• Competitive salary
• Remote-friendly
• Team offsites in San Francisco
