About this position:

As a Senior Security Engineer at Later, you will play a critical role in strengthening and scaling the security foundations that power our platform. This role blends deep security expertise with hands-on engineering, with a particular focus on identity and access management, authentication systems, and secure-by-design development practices.

You’ll partner closely with Engineering, Infrastructure, and Product teams to embed security into our CI/CD pipelines, internal platforms, and customer-facing systems—enabling teams to move quickly while keeping our systems, data, and users safe. This is a high-impact individual contributor role for someone who thinks like a defender, builds like a software engineer, and leads through influence.

What you'll be doing:

Strategy

Define and implement scalable security standards, guardrails, and best practices that support compliance through automated and auditable solutions

Partner with Engineering and Product leadership to align security priorities with business objectives and delivery timelines

emerging risks and proactively design systems and processes that reduce long-term exposure

Technical/ Execution

Own identity and access management across Later’s platform, including authentication, authorization, and secure machine-to-machine (M2M) processes

Design, implement, and maintain secure authentication systems for both internal tools and customer-facing experiences

Harden login systems, establish consistent authentication patterns across services, and ensure secure integration between tools

Build and maintain internal security tooling to support secure development, operational visibility, and compliance workflows

Embed security controls into CI/CD pipelines, including SAST, DAST, SCA, container scanning, secret management, and secure build/deploy practices

Partner with engineering teams to identify vulnerabilities, clearly communicate risk and impact, and drive effective remediation

Team / Collaboration

Provide pragmatic, solution-oriented security guidance during system design and architecture reviews

Collaborate cross-functionally to embed security into development workflows without slowing delivery

Translate complex security concepts into clear, actionable recommendations for both technical and non-technical stakeholders

Act as a trusted partner to engineering teams, balancing risk mitigation with business enablement

Leadership

Lead by influence—raising the security bar through standards, tooling, and mentorship

Set a high standard for secure engineering practices and help others level up their security mindset

Model accountability, ownership, and transparency in security decisions

Research/Best Practices

Stay current on application security, cloud security, and identity best practices
