Software Engineer, Inference

Thinking Machines Lab
San Francisco, CA
On-site

Who this role is best for

Aimed at mid-to-senior level systems engineers who can bridge research and production, with a focus on inference systems and distributed operations.

Best fit for

  • Candidates with experience in deploying and managing large-scale ML inference systems
    — “Experience running production inference for large language models or other large-scale ML systems”
  • Individuals skilled in systems languages and observability for mission-critical services
    — “Proficiency in Python and Go or another systems language”

Things to consider

  • This role requires being on-call and leading incident response for critical systems
    — “Comfortable being on-call and leading incident response for critical production systems”
  • The role demands a balance between cost and capacity as model and traffic scales
    — “Manage capacity and cost tradeoffs for serving infrastructure as traffic and model sizes scale”

How to stand out

  • Highlight your experience with distributed system failures and mitigation strategies
    — “Strong understanding of distributed systems and how they fail at scale”
  • Emphasize your track record with safe, incremental model rollouts in production
    — “Own the rollout process for new models, model versions, and inference optimizations, ensuring safe, incremental deployment to production”
  • Showcase your ability to design resilient systems with redundancy and failover mechanisms
    — “Design for graceful degradation, failover, and redundancy so that serving stays resilient as usage grows”
  • Demonstrate your experience with observability and alerting for production systems
    — “Build and improve observability, alerting, and capacity planning so the team can detect, diagnose, and resolve production issues quickly”
  • Mention your familiarity with inference optimization techniques like batching and caching
    — “Familiarity with inference-specific techniques, such as batching, caching, or quantization, and their operational implications”

ABOUT THINKING MACHINES

The mission of Thinking Machines is to build AI that extends human will and judgment. We are training frontier models with Inkling, developing Tinker to let people make models their own, and crafting interfaces that broaden human-AI communication. We believe the future worth building is human, and we're hiring people who want to build it.

ABOUT THE ROLE

We're hiring a Software Engineer, Inference to own the reliability, scale, and efficiency of the systems that serve our models to real users. Our research and inference teams push the limits of model performance and serving efficiency; this role makes sure those gains reach production safely and stay up — powering Tinker's live, multi-tenant serving and the products built on top of our models.

This is a production-facing systems role at the center of the company. You'll be the bridge between cutting-edge inference techniques and the day-to-day reality of serving real traffic: rollouts, capacity, incidents, and everything that keeps a fast-growing platform online.

WHAT YOU'LL DO

  • Operate and scale the production inference systems that serve live traffic, including Tinker's multi-tenant serving platform
  • Own the rollout process for new models, model versions, and inference optimizations, ensuring safe, incremental deployment to production
  • Build and improve observability, alerting, and capacity planning so the team can detect, diagnose, and resolve production issues quickly
  • Partner with inference and research teams to productionize new serving techniques without compromising reliability
  • Lead incident response for production inference issues, driving root cause analysis and durable fixes
  • Design for graceful degradation, failover, and redundancy so that serving stays resilient as usage grows
  • Manage capacity and cost tradeoffs for serving infrastructure as traffic and model sizes scale

SKILLS & QUALIFICATIONS

MINIMUM QUALIFICATIONS

  • Experience operating large-scale, latency-sensitive production systems
  • Proficiency in Python and Go or another systems language
  • Experience with observability, monitoring, and incident response for production services
  • Strong understanding of distributed systems and how they fail at scale

PREFERRED QUALIFICATIONS

  • Experience running production inference for large language models or other large-scale ML systems
  • Experience with deployment and rollout systems, such as canarying, blue/green deploys, or feature flags
  • Experience with capacity planning and cost optimization for GPU or TPU infrastructure
  • Familiarity with inference-specific techniques, such as batching, caching, or quantization, and their operational implications
  • Comfortable being on-call and leading incident response for critical production systems
  • Comfortable working with high autonomy in a fast-changing, early-stage environment

LOGISTICS

  • Location: This role is based in San Francisco, CA.
  • Compensation: Depending on background, skills and experience, the expected annual salary range for this position is $300,000 - $400,000 USD.
  • Visa sponsorship: We sponsor visas. While we can't guarantee success for every candidate or role, if you're the right fit, we're committed to working through the visa process together.
  • Benefits: Thinking Machines offers generous health, dental, and vision benefits, unlimited PTO, paid parental leave, and relocation support as needed.
