Staff Infrastructure Engineer

What You'll Do

• Lead architectural decisions and technical reviews for infrastructure-critical initiatives.
• Design, build, and own the cloud infrastructure (AWS/GCP) that runs Salient - from compute and networking to storage and observability.
• Develop scalable harnesses that enable coding agents to operate reliably without compromising system stability or code quality.
• Partner closely with the modeling team to optimize the serving and performance of GPU-intensive workloads.
• Drive reliability and performance across the stack by defining SLOs, building robust monitoring and alerting, and leading incident response and postmortems.
• Own developer platform investments that materially improve engineering velocity, including CI/CD, deployment tooling, environments, and internal infrastructure abstractions.
• Establish infrastructure best practices, patterns, and standards as a technical authority across the engineering org.
• Identify and reduce technical debt across infrastructure systems, with a focus on long-term scalability and operational health.

What You'll Bring

• 5+ years of software engineering experience, with 2+ years at the senior or staff level in infrastructure/platform roles, working on large-scale distributed systems.
• Deep expertise in cloud platforms (AWS or GCP) - compute, networking, storage, IAM, and cost optimization.
• Expert in infrastructure-as-code, with a strong track record of building scalable automation systems.
• Extensive experience owning and scaling Kubernetes and CI/CD systems in high-throughput, production environments.
• Track record of building and operating high-availability, high-throughput distributed systems with mature observability practices.
• Strong technical communication - able to document architecture clearly and influence engineering decisions across teams.

Nice to Have

• Background in security.
• Exposure to serving AI/ML workloads.
• Combination of big tech and startup experience.
