Senior/Staff Security & Infrastructure Engineer

CivilGrid is the trusted civil design platform powering affordable infrastructure renewal and growth. We give utilities, civil engineers, and municipalities a single, collaborative source of truth for what's underground so teams can plan, design, and build faster, smarter, and safer.

Our platform consolidates utility records, geotechnical and environmental data, paving moratoriums, and jurisdictional requirements directly from 3,000+ utilities, agencies, and municipalities with full chain-of-custody documentation. Teams at PG&E, Mark Thomas, and dozens of leading engineering firms use CivilGrid to cut research time by up to 88%, reduce project costs, prevent dig-ins, and accelerate delivery on the projects that keep communities running.

We're a venture-backed Series A startup tackling a $4.7T US infrastructure market that has been underserved by software for decades. Founded by industry insiders, each with 10+ years in utilities and civil engineering, we move fast, ship work that matters, and stay close to the customers and field teams we build for.

We're looking for a Security & Infrastructure Engineer to own our security posture and assist in supporting our cloud platform and reliability as we scale into large utilities and civil engineering firms. You'll take over and grow our security program, working across engineering, IT, and leadership. The role is on the Systems team that spans DevOps, SRE, and security. Your focus is security but you will contribute across the team.

This role reports to the Head of Engineering. It is a hybrid role with expectations that you are working from our Boston, MA office at least 3 days per week if hired.

• →

  Partner with engineering to embed reliability and security into the SDLC and infrastructure decisions

• →

  Run our security program: SOC 2 readiness and audits, vendor reviews, access controls, endpoint security, and threat modeling

• →

  Define and enforce policies for identity, secrets, data handling, and production access across the company

• →

  Lead incident response for both security events, and some reliability events, from detection through resolution and follow-up

• →

  Harden and monitor our GIS servers (Windows Server) alongside our AWS platform

• →

  Build and maintain our Trust Center, and lead security reviews with customers

• →

  Contribute to our AWS environment end to end: VPC architecture, ECS, RDS, secrets management, IAM, networking, and cost optimization

• →

  Contribute to improving reliability practices: SLOs, observability, alerting, on-call rotation, runbooks, and blameless post-incident reviews

• →

  The tech:

  • →

    AWS ECS, Postgres on RDS managed with CDK

  • →

    GitHub, Datadog, Slack, Notion, Drata

• At least 5-8 years of experience across product security, platform security, or security engineering, with hands-on experience with DevOps or SRE of production AWS infrastructure

• Experience running or supporting a SOC 2 program, including evidence collection, control design, and auditor coordination

• Deep working knowledge of AWS (VPC, ECS, RDS, IAM, Secrets Manager, CloudWatch) and infrastructure-as-code (Terraform, CDK, or equivalent)

• Experience running vulnerability management, from scanner findings and outside reports to fixes shipped

• Track record of improving reliability in production: defining SLOs, building observability, running on-call, and leading post-incident reviews

• Startup ready: autonomous, moves fast, takes initiative without being asked

• Strong verbal and written communication, able to articulate ideas clearly and collaborate effectively

• Experience supporting B2B products sold into regulated industries (utilities, energy, public sector)

We're a small, but rapidly growing team that ships. Expect direct feedback, real ownership from day one, and proximity to customers — huge utilities, public agencies, and engineering firms whose work depends on what we build. We default to in-person collaboration where it matters and remote-friendly flexibility otherwise. We hire people who care deeply about their craft and the communities our customers serve.
