As a Software Engineer on the ML Infrastructure team, you will design and build the next generation of foundational systems that power all ML Infrastructure compute at Scale - from model training and evaluation to large-scale inference and experimentation.
Our platform is responsible for orchestrating workloads across heterogeneous compute environments (GPU, CPU, on-prem, and cloud), optimizing for reliability, cost efficiency, and developer velocity.
The ideal candidate has a strong background in distributed systems, scheduling, and platform architecture, and is excited by the challenge of building internal infrastructure used across all ML teams.
You will:- Design and maintain fault-tolerant, cost-efficient systems that manage compute allocation, scheduling, and autoscaling across clusters and clouds.
- Build common abstractions and APIs that unify job submission, telemetry, and observability across serving and training workloads.
- Develop systems for usage metering, cost attribution, and quota management, enabling transparency and control over compute budgets.
- Improve reliability and efficiency of large-scale GPU workloads through better scheduling, bin-packing, preemption, and resource sharing.
- Partner with ML engineers and API teams to identify bottlenecks and define long-term architectural standards.
- Lead projects end-to-end — from requirements gathering and design to rollout and monitoring — in a cross-functional environment.
- 4+ years of experience building large-scale backend or distributed systems.
- Strong programming skills in Python, Go, or Rust, and familiarity with modern cloud-native architecture.
- Experience with containers and orchestration tools (Kubernetes, Docker) and Infrastructure as Code (Terraform).
- Familiarity with schedulers or workload management systems (e.g., Kubernetes controllers, Slurm, Ray, internal job queues).
- Understanding of observability and reliability practices (metrics, tracing, alerting, SLOs).
- A track record of improving system efficiency, reliability, or developer velocity in production environments.
- Experience with multi-tenant compute platforms or internal PaaS.
- Knowledge of GPU scheduling, cost modeling, or hybrid cloud orchestration.
- Familiarity with LLM or ML training workloads, though deep ML expertise is not required.
Compensation packages at Scale for eligible roles include base salary, equity, and benefits. The range displayed on each job posting reflects the minimum and maximum target for new hire salaries for the position, determined by work location and additional factors, including job-related skills, experience, interview performance, and relevant education or training. Scale employees in eligible roles are also granted equity based compensation, subject to Board of Director approval. Your recruiter can share more about the specific salary range for your preferred location during the hiring process, and confirm whether the hired role will be eligible for equity grant. You’ll also receive benefits including, but not limited to: Comprehensive health, dental and vision coverage, retirement benefits, a learning and development stipend, and generous PTO. Additionally, this role may be eligible for additional benefits such as a commuter stipend.
