We're seeking a Senior Silicon Software Development Infrastructure Engineer to architect, build and operate the infrastructure that accelerates silicon development at Annapurna Labs. In this role, you'll design and deliver the platforms, tooling, and automation that enable our chip design teams to iterate faster, validate more thoroughly, and bring transformative silicon to market. You'll work at the intersection of cloud infrastructure, high-performance computing, and electronic design automation—building systems that directly impact AWS's ability to innovate in custom silicon.

This is a unique opportunity to shape infrastructure that supports chip development while working with world-class engineers across hardware, software, and operations disciplines.

Key job responsibilities

Customer-Obsessed Infrastructure Development:

• Partner directly with silicon design, verification, emulation, formal verification, and software teams to deeply understand their development workflows, pain points, and iteration cycles.
• Build customer-facing tooling including command-line interfaces, REST APIs, and automation services that eliminate manual toil and reduce time-to-results
• Gather continuous feedback from internal customers and rapidly iterate on solutions. Benchmark infrastructure based on silicon development workflows to provide internal customers with the optimal resources for silicon development.

Own End-to-End Platform Delivery:

• Design, implement, and operate cloud infrastructure (AWS preferred) and high-performance computing clusters using schedulers like Slurm
• Build and maintain CI/CD pipelines for infrastructure-as-code, container images, service deployments, and cluster configuration changes with comprehensive testing, staged rollouts, and safe rollback mechanisms
• Take full ownership of platform reliability, performance, and cost efficiency—from initial design through production operation and continuous improvement

Deliver Results Through Automation and Observability:

• Develop data pipelines that ingest metrics, logs, and workflow results from distributed systems
• Design and operate databases that capture workflow metadata, job outcomes, and resource utilization patterns
• Build dashboards and alerting systems that surface actionable insights on efficiency, utilization, reliability, and cost trends
• Establish monitoring, incident response processes, runbooks, and documentation that enable operational excellence

Invent and Simplify Systems:

• Identify opportunities to simplify workflows and reduce complexity in silicon development infrastructure
• Design pragmatic, scalable solutions that balance immediate needs with long-term maintainability
• Challenge assumptions and propose innovative approaches to infrastructure problems, always asking "what's the simplest thing that could work?"
• Build reusable abstractions and platforms that eliminate repetitive work across multiple teams and chip programs

A day in the life
As a Senior Software Development Engineer at Annapurna Labs working on silicon infrastructure, you'll start your day investigating any anomalies in job completion rates or resource utilization. You might spend your morning collaborating with a design verification team to optimize their regression workflows, identifying bottlenecks in their CI pipeline and proposing architectural improvements that could reduce iteration time by hours.

In the afternoon, you could be designing a new API that abstracts license server complexity for emulation teams, or implementing autoscaling policies for a Slurm cluster that needs to handle unpredictable workload spikes while optimizing costs. You'll participate in architecture reviews, contribute to postmortems when incidents occur, and continuously refine the observability dashboards that give teams real-time visibility into their development velocity.

Throughout the day, you'll balance immediate customer needs—unblocking a team waiting for compute capacity—with longer-term platform investments that will scale across multiple chip programs. You'll write code, review infrastructure-as-code changes, and collaborate across time zones with engineers who depend on the systems you build. Every improvement you deliver directly accelerates the path from RTL to silicon.

About the team
At Annapurna Labs, your infrastructure work directly enables breakthrough innovations in custom silicon that power AWS and transform industries. You'll collaborate with world-class chip designers, verification engineers, and software developers who are pushing the boundaries of what's possible. We offer the resources and scale of AWS with the innovation culture and technical depth of a focused silicon team.

If you're passionate about building infrastructure that accelerates innovation, thrive on customer obsession and ownership, and want to see your work enable the next generation of AWS silicon—we want to hear from you.
