Senior DevOps Engineer - Security at Coalesce

Coalesce is on a mission to make the modern data stack effortless for everyone. Our platform powers data modeling, transformation, catalog, and governance for some of the world's most important analytics teams. Customers rely on Coalesce as the core platform for running their data operations, enabling the discovery and transformation of their data into useful, consistent analytics insights that power their business.

We are small and nimble, but mighty and now… growing! We are a team of DevOps generalists tasked with building and maintaining the cloud platform the Coalesce application runs on. We work to ensure that the platform is scalable, resilient, auditable and reproducible and we do this by embracing Infrastructure as Code (IaC) using Terraform and automation, constantly refining and improving to add value to the business. As a department we’re responsible not only for cloud infrastructure, but also CI/CD used to test and deploy our application, and security compliance + audit in partnership with our Security Team.

The App

• Coalesce is built on TypeScript and React, and runs on Node.js with some Go and Python in different spots. Postgres, Redis and Firebase for storage.

The Infra

• Managed Kubernetes across AWS, Azure, GCP (20+ deployments)

• Kubernetes resources are managed via Kustomize, deployed using ArgoCD

• Cloud infrastructure is deployed and managed using Terraform

• GitHub for source control + GitHub Actions for CI/CD

• DataDog, PagerDuty, Tailscale, Slack, Lucid, Zoom and of course Snowflake, Databricks & Fabric

We’re looking to add a new team member that can help with all the things we do, and help us do it more securely. The applicant will help develop and lead strategic security initiatives to ensure our infrastructure is secure and compliant, that no keys or credentials ever land in our repos, and that our code is fully tested before it’s deployed to the public. There will be considerable work with kubernetes and Github Actions in general, with a specific focus on the security aspects of each. Understanding our SDLC and how to secure things throughout will be key.

Cloud infrastructure is another piece of the puzzle for this position.

• Design, implement, and manage our CI/CD pipelines, integrating security best practices at every stage. Troubleshoot test failures and refine the pipeline to improve outcomes and speed things along.

• Automate security testing and vulnerability scanning as part of the code development lifecycle.

• Ensure our Terraform is deploying secure infrastructure each and every time.

• Monitor and respond to security alerts & incidents

• Collaborate with Infrastructure and Development teams to improve security posture and processes across the organization.

• Conduct security audits and risk assessments, identifying and mitigating potential vulnerabilities.

• Minimum 5+ years of experience in DevOps, SRE, or platform engineering roles with a strong emphasis on cloud infrastructure, automation and security.

• Deeply proficient in Kubernetes and associated toolsets, with expertise in related security principles including cluster and deployment policies

• Deep expertise with building, scaling, and optimizing CI/CD pipelines and integrating security scanning, code analysis, and compliance tools (e.g., CodeQL, Trivy, Snyk)

• Extensive cloud infrastructure experience & familiarity around security concepts in the cloud

• Strong background with IaC using Terraform across AWS, GCP, and/or Azure.

• Familiarity with secret management tools and patterns to ensure security

• Proficiency in scripting languages like Python, Go, or Bash, for automation and custom security tooling.

• Understanding of cloud security & IAM best practices, zero-trust principles

• Solid understanding of networking principles and protocols, especially as it relates to networking in the clouds.

• Experience adhering to security frameworks (e.g., SOC 2, NIST, ISO 27001) and how to align CI/CD and infra with compliance.

Bonus Points

• Previous Experience as a Data Engineer, working with ETL pipelines, Data Warehouses

• CISM, CISSP, or other security certifications

• AWS, Azure, or GCP Associate or Professional Level Certifications (Architect, Developer, Security, etc)

• Kubernetes certifications including CKA, CKS, KCNA, KCSA, CKAD
