Sr. DevOps Engineer

Company & Mission Overview:

Our mission: We exist to connect climate and financial risk.

Who we are: First Street is the standard for Climate Risk Financial Modeling. For over a decade, we’ve been translating climate risk into decision-useful financial outcomes for investors, businesses, communities, and property owners worldwide. With backing from world-class firms, including Innovation Endeavors, Galvanize, General Catalyst, and others, our team has raised millions to change how the global economy thinks about climate change.

Our data: We’ve assembled leading climate scientists and economists to develop transparent, peer-reviewed methodologies to calculate the past, present, and future climate risk for properties and asset classes spanning real estate, infrastructure, and companies. Using physics-based deterministic models, we predict the likelihood of floods, wildfires, hurricanes, and other hazards at any location on Earth, along with associated damage and downtime.

Our customers: We aim to incorporate climate risk data into every financial decision made today. We are relied on every day by:

• Institutional investors like Norges Bank Investment Management and Blackstone.

• Banking enterprises, including Bank of America and Fifth Third.

• Government bodies ranging from Fannie Mae to the US State of Connecticut.

• Millions of everyday users on Zillow, Redfin, Realtor.com, Homes.com, and more.

Come join us and use your talents to change the world.

Team Role & Overview

We’re hiring a Sr. DevOps Engineer to take ownership of responsibilities that have historically been shared across engineering. You won’t be “building from zero” - we already have systems in place - but you will bring a high level of ownership over all aspects of your technical practice: smoother deployments, stronger reliability, clearer observability, tighter identity/access controls, and a more repeatable infrastructure foundation.

What you’ll do:

Over your first year, success looks like measurable improvements across:

• Reducing deployment pain: make releases simpler, safer, and faster through better automation, consistent environments, and strong CI/CD practices.

• Improving observability and on-call: strengthen monitoring, alert quality, and incident response so on-call is humane and effective

• Formalizing Infrastructure as Code (IaC): drive repeatability and change control for infrastructure and platform configuration. Why? We are quickly scaling to global, multi-region infrastructure.

• Cost controls: introduce practical FinOps hygiene (visibility, ownership, guardrails, right-sizing).

• Compute environments: own and evolve our platform across AWS and on-prem compute environments (you’ll have the opportunity to collaborate with our High Performance Compute team).

• On-call quality: reduce noisy alerts, define SLOs/SLIs where useful, and strengthen incident response practices (runbooks, postmortems, follow-ups).

• Operational workflows: Lead efforts to standardize operational workflows and reduce “institutional knowledge” dependencies across the team.

What you’ll need:

• Strong hands-on DevOps/platform ownership experience, ideally having been the primary owner) in a prior role.

• Deep comfort operating production public cloud systems: debugging, incident response, performance triage, and operational discipline.

• Practical experience improving CI/CD and deployment reliability.

• Fluency with cloud infrastructure (AWS strongly preferred) and containerized workloads (Kubernetes experience strongly preferred).

• Security-minded approach, especially around identity and access management and SSO/SAML concepts.

• Ability to work independently with minimal hand-holding, while collaborating effectively across engineering.
