The Senior Security Platform Engineer leads the design and operation of core infrastructure that supports security detection, observability, and response at Lumin Digital.
In this role, you will architect secure and scalable systems, mentor peers, and partner across engineering teams to promote secure-by-default development and operational patterns.
This role blends deep technical expertise with strategic ownership of security systems, focusing on reliability, automation, and influencing broader engineering practices through thought leadership and mentorship.
Essential functions include architecting multi-region and multi-account telemetry systems that support ingestion, storage, and analysis of security-relevant data at scale.
You will define and enforce the separation of duties and access controls in CI/CD and infrastructure provisioning workflows.
The role involves leading the design and rollout of policy-as-code frameworks and pipeline guardrails to improve deployment security across teams.
You will set service-level objectives (SLOs) for security services and lead capacity planning, monitoring strategy, and performance optimization.
Guiding incident response for complex or high-severity issues, including technical leadership during resolution and facilitating post-incident reviews, is a key responsibility.
You will mentor engineers across the organization in secure platform practices and review contributions for architectural integrity and security posture.
The role also includes driving initiatives that embed security into developer workflows, such as secure ephemeral environments, secrets management, and test isolation.
Collaboration with platform and product leadership to influence roadmaps and align engineering efforts with long-term security objectives is essential.
Requirements:
A Bachelor’s degree in Computer Science, Information Security, or a related field, or equivalent self-directed study with demonstrated competency in security operations, cloud engineering, or platform reliability is required.
Six (6) or more years of professional experience in security engineering, platform reliability, or cloud infrastructure is necessary.
Experience designing and leading large-scale secure systems in cloud-native environments, preferably AWS, is required.
A proven track record of mentoring engineers, leading initiatives, and driving improvements to reliability and security posture across organizations is essential.
Advanced knowledge of cloud security best practices, including requirements and guidance from security and compliance frameworks such as SOC 2 Trust Services Criteria, PCI Data Security Standard, the CIS Benchmarks, and the AWS Well-Architected Framework is needed.
Advanced knowledge of security best practices for Kubernetes, CI/CD, AWS, and cloud-native systems is required.
Expertise with infrastructure-as-code tools (e.g., Terraform) and pipeline automation for secure deployments is necessary.
Excellent troubleshooting, incident management, and monitoring skills across distributed systems are required.
Strong communication and collaboration abilities, with a focus on mentorship and cross-team influence, are essential.
The ability to influence engineering practices and advocate for security priorities in roadmap discussions is necessary.
