About the role

We're hiring a Security Engineer to build and operate the controls that protect Allium's infrastructure, applications, employee systems, and use of AI. You'll work closely with Engineering and the person leading our security program to investigate threats, implement practical fixes, and automate security work.

As AI agents gain access to code, data, and tools, security needs to cover both human and machine activity. You'll help secure how agents operate while strengthening our defenses against automated attacks, credential theft, and compromised software dependencies. This is a hands-on engineering role: you'll write code, test controls, investigate real signals, and take findings through remediation.

What you'll do

• Secure cloud infrastructure and access. Implement least privilege, phishing-resistant authentication, short-lived credentials, controlled privileged access, and reliable provisioning and deprovisioning. Improve cloud configuration, managed credential storage, and network protections with service owners. Improve secrets scanning and prevent credentials from entering source control.

• Secure AI agents and developer tools. Help implement permissions, execution isolation, network restrictions, and audit trails for coding assistants, agents, and tool integrations, including MCP. Test how untrusted content could trigger prompt injection, tool misuse, or unintended data access, and build safeguards at the point where actions execute.

• Build detection and response. Correlate identity, cloud, workload, and CI/CD telemetry to detect credential theft, unusual access, unauthorized agent actions, suspicious software changes, and data exfiltration. Investigate attacks across systems, reduce alert noise, and test response procedures with system owners, including session revocation, exposed-credential rotation, and removal of unauthorized access.

• Reduce software supply-chain risk. Assess dependencies, CI/CD workflows, third-party integrations, and developer environments. Partner with engineers to validate findings, protect build and deployment credentials, and remediate vulnerabilities.

• Move quickly on relevant threats. Maintain visibility into internet-facing services, including developer tools and management interfaces. Evaluate new vulnerabilities and active exploitation against our actual exposure. Help patch, isolate, revoke credentials, or apply compensating controls with service owners, then verify that the response worked.

• Automate and document. Use code and APIs to improve access reviews, configuration checks, evidence collection, and remediation tracking. Use AI thoughtfully for security work, validating its output and protecting sensitive data.

• Support employee security and enterprise assurance. Deploy, validate, and maintain endpoint protections and device security baselines, including prevention settings, tamper protection, encryption, and timely updates. Work with the owner of employee IT on identity and SaaS controls. Provide clear technical evidence for audits and customer reviews, and maintain useful runbooks.

What we're looking for

• Typically 4+ years of relevant security, infrastructure, or software engineering experience, with direct responsibility for implementing security controls.

• Hands-on experience with a major cloud platform and a strong foundation in identity, networking, operating systems, and access control.

• Depth in at least two relevant areas, such as cloud security, detection and response, application security, vulnerability management, or corporate security.

• Experience investigating technical problems from logs and system behavior, testing hypotheses, and following issues through to resolution.

• Clear communication, practical judgment, and constructive working relationships with engineers and business teams.

• Obsessiveness - The best people at Allium cannot put a problem down once they pick it up. We care more about the work than is strictly rational. Institutions trust us because our data is right. Right means caring about the small things. The decoded contract that ships with one wrong field. The label that is 99% accurate but wrong on the address that matters. The query that runs in 4 seconds when it should run in 400 milliseconds. Most companies tolerate these. We do not.
