SENIOR IT INFRASTRUCTURE ENGINEER

SENIOR IT INFRASTRUCTURE ENGINEER

San Mateo, Bay Area/CA

MUST HAVE A TELECOM/5G EXPERIENCE:

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.

NICE TO HAVE ATTRIBUTES/SKILLS:

· - 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).
