As a Senior IT & Infrastructure Engineer with our SF Bay Area client, you will be the engineer keeping their mid-peninsula engineering organization running, owning AWS systems, monitoring, lab equipment, and the internal IT services that engineering depends on every day. You will work hands-on across Linux administration, build pipelines, virtualization, AWS, lab operations, and tier-1 internal support, and partner closely with our 5G DevOps counterpart in Romania on shared infrastructure standards. This is a broad, hands-on role for someone energized by being the person engineers come to when things need to work. JOB RESPONSIBILITIES What You’ll Do: • Architect with Purpose: Design cloud-native infrastructure in AWS that scales seamlessly across regions and workloads. • Automate Relentlessly: Build Terraform modules and tooling to make infrastructure creation fast, safe, and repeatable. • Engineer for Reliability: Implement fault-tolerant, self-healing systems to minimize downtime and maximize performance. • Secure from the Start: Embed IAM, networking, and observability into every layer of the stack. • Optimize and Evolve: Continuously refine cost, performance, and deployment workflows as we scale. What You Bring: • 3–5 years of experience building and managing AWS environments. • Deep knowledge of Terraform and Infrastructure-as-Code best practices. • Familiarity with CI/CD pipelines, containerization (Docker), and monitoring stacks. • A systems thinker who thrives on structure, scalability, and clean automation. • Curiosity, initiative, and a drive to build things that just work. Why You’ll Love Working Here: • Build foundational infrastructure that powers cutting-edge AI products. • Work with a brilliant, passionate team that values both speed and precision. • Competitive salary, equity, and career growth opportunities in a fast-scaling startup. • Flexible, trust-based culture-autonomy encouraged, bureaucracy not included. • Great benefits package and a prime Cambridge office location. SHOULD HAVE ATTRIBUTES/SKILLS • - Experience coordinating with external IT vendors and managing compliance-adjacent IT projects (security audits, vendor management). • - Experience operating in a regulated or compliance-sensitive engineering environment. • - Exposure to early-stage or high-growth startup environments. • - Experience supporting firmware or embedded engineering teams, including hardware-in-the-loop (HITL) test integration into build pipelines. • - Familiarity with 5G or LTE telecommunications at a working level. • - Operational experience with lab equipment, test rigs, or robotics infrastructure in an engineering organization. • - Working familiarity with code quality and static analysis tooling (SonarScanner, Pytest). • - Familiarity with Elasticsearch operations (client’s legacy systems; may require migration or retirement).
