Role – Lead Security Engineer

About the Role

We are seeking a Lead Security Engineer to own and scale our Application and Cloud Security programs. You will be responsible for designing and enforcing security best practices across our codebase, cloud infrastructure, development lifecycle, and production environments.

This role will partner closely with engineering, product, and compliance teams to embed security into every stage of our build, deploy, and delivery processes. You are expected to drive a shift-left security culture, where secure design, secure development, and proactive detection are core to how we build and operate.

Key Responsibilities

Application Security

• Perform security assessments across our application stack, including threat modeling, code reviews, dynamic scanning, and penetration testing.
• Build and maintain secure SDLC practices, including integration of security checks into CI/CD pipelines.
• Guide teams in secure design patterns, including secure authentication, input validation, access control, session management, and secure storage.
• Continuously monitor and remediate vulnerabilities in source code and dependencies (SCA, SAST, DAST).
• Partner with engineering teams to define and enforce coding standards aligned with OWASP and CWE guidelines.

Cloud & Infrastructure Security

• Design and maintain secure configurations for AWS environments, including networking, identity management (IAM), encryption, and logging.
• Implement and manage security services such as GuardDuty, Inspector, Security Hub, and other cloud-native tools.
• Define and enforce infrastructure-as-code (IaC) security controls using tools such as Terraform, CloudFormation, or policy-as-code frameworks (e.g., OPA, Sentinel).
• Lead efforts in runtime protection, including workload scanning, intrusion detection, and anomaly alerting.
• Ensure centralized, secure log collection, monitoring, and alerting across all infrastructure components.

Security Architecture & Best Practices

• Champion a shift-left approach to security —collaborating with developers early in the SDLC and providing actionable feedback during design, build, and review phases.
• Collaborate with product managers and infrastructure leads to ensure security is embedded into architectural decisions, particularly for high-risk features or regulated workflows.
• Define and promote secure defaults, least-privilege access, and zero-trust architectural principles.
• Ensure strong key management and encryption standards are applied across data at rest, in transit, and in use.

Governance, Risk & Compliance

• Support compliance initiatives by building and documenting enforceable security controls.
• Work with auditors and risk teams to demonstrate maturity of security processes and ongoing improvements.
• Establish internal security policies, operational procedures, and regular audit activities.

What We Expect

• Lead the adoption of security by design across engineering functions.
• Embed continuous security testing into our CI/CD pipelines.
• Maintain a developer-centric approach to security—minimizing friction while enforcing strong protections.
• Build scalable policies and automation for secrets management, code signing, and environment hardening.
• Keep pace with evolving security threats, technologies, and tools, proactively updating controls and detection mechanisms.
• Represent security posture to executive and customer stakeholders with clarity and confidence.

What You Bring

Required

• 6+ years of experience in security engineering with a primary focus on application and cloud security
• Proficiency with programming languages like, Java, Python, JavaScript and web technologies (e.g., HTML, CSS, SQL).
• In-depth knowledge of application security vulnerabilities, threat modeling, and SDLC integrations
• Deep familiarity with Cloud security architecture and services (AWS - IAM, VPC, KMS, GuardDuty, CloudTrail, etc.)
• Experience with DevSecOps tools and practices, including SAST, DAST, container scanning, and infrastructure scanning
• Hands-on experience in implementing industry best practices in access control, encryption, and security observability
• Excellent communication skills, with the ability to collaborate across engineering, product, and compliance teams
• Bachelor's degree in Computer Science, Information Security, or a related field.

Preferred

• Experience in high-compliance industries such as financial services, healthcare, or government
• Familiarity with policy-as-code, secrets management tools, and container security
• Certifications such as OSCP, AWS Security Specialty, or CISSP

Why Join Us?

• Remote-first culture – Work from anywhere, with top-tier colleagues.
• Security is not a checkbox—it is fundamental to our success and product trust.
