DevSecOps Engineer

About Maxima

Nobody went into accounting to spend the first week of every month matching transactions by hand. Maxima was built so they don't have to. Our agents do the accounting work itself: journal entries, transaction matching, reconciliations, and flux analysis, continuously and with a full audit trail. Accountants review and approve. Nothing posts without a person signing off. We remove the grind, not the human.

Maxima is the agentic AI platform for enterprise accounting. Our three co-founders scaled finance at Rubrik from $5M ARR to a $15B NYSE IPO, built the reconciliation and billing systems behind Netflix's $32B in annual revenue, and built AI infrastructure serving two billion monthly users at Meta. We've raised $41M from Redpoint Ventures, Kleiner Perkins and Audacious Ventures, joined by former BlackLine executives and the CFOs of Rubrik and Vanta. To date we've processed more than $400B across 350M transactions at 100.00% accuracy, for customers including Scale AI, Rippling, Glean, Zendesk, Handshake, Zip, and Decagon.

We're early and moving fast. The playbook here gets written, not inherited, and the person closest to the work makes the call. We're looking for people who build from first principles and hold themselves accountable for what actually lands — people who'd rather build the category than join it. Everything you need to know is below.

The role

We are working on some of the hardest problems in enterprise automation, with an engineering team that includes staff-level talent from Robinhood, Glean, Google, Netflix, and Meta. The system handles high-volume financial data and complex accounting workflows, and every execution has to be accurate and reliable, because the output is a company's books.

You will own security across Maxima's software development lifecycle: CI/CD pipelines, cloud infrastructure on GCP, container and artifact hardening, secrets and key management, and the controls behind our SOC 1, SOC 2, and ISO 42001 compliance. Customers trust Maxima with their general ledger, and their auditors ask how we protect it. Your work is a large part of the answer.

It is a hands-on role in a full-stack environment, with a shift-left approach to security and a share of developer infrastructure work.

What you'll do

• Implement and manage DevSecOps practices across the SDLC with a shift-left approach to security

• Design and harden CI/CD pipelines such as GitHub Actions, with minimal permissions and OIDC with Workload Identity Federation for cloud deployments

• Integrate and enforce SAST, dependency scanning, and secret scanning (for example Trufflehog or GitGuardian) so builds fail on high-severity issues

• Secure GCP infrastructure with least-privilege IAM, VPC firewall rules, and Google Secret Manager, and manage encryption and key rotation with Cloud KMS

• Harden containers and artifacts: multi-stage builds, image vulnerability scanning, and artifact signing with tools such as Cosign

• Keep application code to secure coding practices, including input validation, output encoding, and secure authentication and session management through our Descope integration

• Monitor CI/CD pipelines and production (GCP and Datadog) for anomalies, security events, and audit logs

• Maintain the documentation and controls for SOC 2, SOC 1, and ISO 42001

• Help with developer infrastructure, including deployment automation and internal tooling
  

What we're looking for

• 4 or more years in DevSecOps, security engineering, or a related role focused on CI/CD pipeline security

• Bachelor's degree in any engineering discipline; computer science preferred but not required

• Experience securing cloud environments, preferably GCP, including IAM, Secret Manager, VPC controls, and Cloud KMS

• Hands-on experience hardening CI/CD systems such as GitHub Actions or Blacksmith

• Proficiency in application security practices (SAST, DAST, secret scanning) and a deep understanding of common anti-patterns such as hard-coded secrets and insufficient input validation

• Proficiency in Go, TypeScript, Python, or similar languages for automation and development

• Comfort with Kubernetes and other container orchestration platforms

• Familiarity with SOC 2, PCI DSS, or ISO 42001, and experience producing evidence for auditors

• Strong verbal and written communication skills, and the ability to handle the pace of a startup
  

Where and how you'll work

This role is based in our downtown Toronto office, near Union Station. We value in-person collaboration and are in office four to five days a week for our on-site roles.

Why join Maxima

• The work. Agentic accounting is a category being defined right now, and Maxima is one of the companies defining it. The product does the accounting work itself, so what you build, sell, or deploy shows up in a customer's books

• The people. Founders who ran the finance org at Rubrik and built the close systems at Twitter and Netflix. Engineers from Robinhood, Glean, Google, Netflix, and Meta. Controllers and accountants on the team who have closed books themselves. Small teams in San Mateo and Toronto that work in the same room, say what they think, and hold a high bar

• The benefits. Competitive salary, 401(k) for US employees, unlimited PTO, lunch in the office, and commuter benefits

• The process. A person reads every application, and we tell you where you stand at every stage
