The Role

As a Senior Security Engineer, you will be the cornerstone of our product and cloud security posture. This is a hands-on role for a technical leader responsible for architecting, building, and automating security controls across our ecosystem.

You're obsessed with security, you know how to prioritize real risks, and you excel at cutting through any false sense of security. You'll thrive here if you enjoy solving complex challenges and want to play a foundational role in building our security program with a high degree of autonomy.

What You'll Do:

• Architect and lead the design and implementation of our security controls across our cloud infrastructure, applications, and CI/CD pipelines.
• Coach and mentor developers and engineers on secure coding practices, threat modeling, and cloud security, fostering a security-first culture within our teams.
• Own the security of the SDLC by integrating and automating security tools (SAST, DAST, SCA) and championing secure coding practices with our development teams.
• Engineer and maintain a robust cloud security posture, primarily in AWS, by implementing and managing security services, automating compliance checks, and hardening configurations.
• Own the response to security alerts by investigating, triaging, and remediating threats across our cloud and application environments.
• Architect and guide our IAM strategy, collaborating with engineering teams to ensure secure, least-privilege access for all human and machine identities.
• Automate everything. Use your coding and scripting skills to automate security processes, alerts, and remediation actions to improve our security response time and efficacy.

Requirements

• 5+ years of hands-on experience in a technical security engineering role.
• Deep expertise in Cloud Security, particularly with AWS and Cloudflare. You have hands-on experience with services like AWS IAM, Security Hub, GuardDuty, WAF and their equivalents.
• A genuine passion for cybersecurity, demonstrated by staying current with the latest industry trends, attack vectors, and threat intelligence.
• Proven experience embedding security into the CI/CD pipeline and working with tools for SAST, DAST, and SCA.
• Solid understanding of industry security frameworks such as the NIST Cybersecurity Framework (CSF), CIS Benchmarks, or the CSA Cloud Controls Matrix.
• Strong proficiency in at least one language for automation and security tooling (e.g., Python, Go, Bash), with experience in TypeScript being a major plus.
• Hands-on experience with Infrastructure as Code (IaC) and its associated security challenges (e.g., Terraform, CloudFormation).
• An ownership mindset. You are a proactive, accountable, and results-driven professional who can work autonomously to drive change.
• Relevant security certifications (e.g., CISSP, AWS Certified Security, CEH) are a plus, but practical experience is paramount.

Benefits

• A lean, focused company, offering a flexible working environment.
• The opportunity to work with and learn form a highly skilled, talented team.
• A great company culture, where accountability is innate, transparency is key and competency is virtue.
• Being part of a small, tight knit, caring community.
• Work equipment of your choice.
• Private health insurance.
• Learning budget.
• Parking/transport or co-working allowance.
• Company wide and team based get togethers.
