Principal Software Engineer, Security & Compliance

CoCounsel is our most advanced AI offering to date — combining generative and agentic AI capabilities to help legal professionals move beyond prompting and start delegating. As a Principal Software Engineer focused on Security & Compliance, you will set the technical direction for how CoCounsel earns and maintains the trust of law firms, corporate legal departments, and government agencies that rely on us with privileged, sensitive, and regulated data every day.

You will own the architecture and engineering practices behind our SOC 2, ISO 27001/42001, HIPAA, and FedRAMP programs, turning compliance requirements into resilient, well-instrumented systems rather than one-off audit exercises.

This role sits at the intersection of the CoCounsel Legal engineering organization and our security, privacy, and legal/compliance teams, partnering closely with platform, identity, and AI/ML engineering to deliver world-class, provably trustworthy legal AI experiences at scale.

• Own the compliance architecture:
  
  Understand and evolve the technical controls that satisfy the landscape of compliance; including but not limited to SOC 2 Type II, ISO 27001/42001, HIPAA, and FedRAMP (Moderate/High) requirements across CoCounsel's infrastructure, data pipelines, and AI systems. Work to understand implications of new compliance and/or certifications.
  
  Your decisions will shape how every product line proves trust to customers and auditors.
• Build compliance as code:
  
  Look to help make the manual better, determine where point-in-time audit prep can be replaced with automated evidence collection, continuous control monitoring, and policy-as-code so that compliance state is observable and provable at any time, not just during an audit window.
• Engineer for real production scale and sensitivity:
  
  Design encryption, key management, data residency, tenant isolation, and audit logging for systems handling millions of privileged legal documents and thousands of concurrent AI interactions from professionals doing time-sensitive work.
• Technical leadership and cross-functional influence:
  
  Partner with Security, Legal, Privacy, and Product to translate regulatory and contractual requirements (customer security questionnaires, DPAs, government agency requirements) into engineering roadmaps. Mentor staff and senior engineers, raising the bar on secure-by-design development, threat modeling, and incident response across the org.
• Reliability and assurance:
  
  Establish SLOs, observability, and incident response practices for compliance-critical systems, and build the internal tooling (dashboards, alerting, control testing) that gives engineering, security, and leadership real-time confidence in our control environment.

• Bachelor's Degree in Computer Science, Computer Engineering, a related field, or equivalent experience.
• Direct, hands‑on experience building or operating production systems that achieved and maintained SOC 2 Type II, ISO 27001 (and/or 42001), and HIPAA compliance — not just reading about it in a policy document.
• Experience supporting a FedRAMP authorization process (SSP development, control implementation, 3
  
  PAO assessments, or Con Mon) at the Moderate or High baseline.
• Deep backend engineering expertise (Python, Java, Go, or similar) and experience with production systems on a major cloud provider (AWS preferred), including how to implement controls natively in cloud infrastructure rather than bolt them on.
• Working knowledge of security control frameworks such as NIST 800-53, NIST CSF, or CIS Benchmarks, and the ability to map technical implementation to specific control requirements.
• Hands-on experience with identity and access management — authentication and authorization at scale (SSO, SAML, OIDC, OAuth 2.0, RBAC/ABAC), encryption and key management, and audit logging.
• Proven track record owning large, complex compliance or security initiatives end-to-end: architecture, execution, audit readiness, and long-term operation.
• Excellent communication skills and the ability to partner with auditors, security, legal, product, and engineering teams in a fast-moving environment.

• Experience…
