Backed by top-tier investors like Bessemer, KKR, and Revolution, we build category-defining technology, and we're doing it with world-class people, processes, and products.\nTo learn more, visit our website\nWe work with the majority of the Top 500 firms in the country. We're replacing brittle, decades-old accounting practice management systems with software accounting firms can actually trust, and we have rare product-market fit in an industry that's about to change permanently.\nAbout the Role\nWe're looking for a Principal Security Engineer to help strengthen and mature engineering security at Aiwyn.\nThis is a hands-on technical leadership role focused on securing our SaaS platform, development infrastructure, and software delivery systems. You'll partner closely with engineering leadership and teams to identify risks, improve security practices, and build the tooling and automation needed to make secure development easier.\nYou'll play a key role in advancing our engineering security capabilities, with a particular focus on software supply chain security, vulnerability management, and secure development practices. Working alongside engineering leadership, you'll help shape our security strategy and drive the technical initiatives that support it.\nWe're looking for a strong engineer with security expertise, sound judgment, and a willingness to tackle new challenges. You don't need to know everything, but you should be comfortable taking ownership, learning quickly, and turning security challenges into practical solutions.\nWhat You'll Do\nSoftware Supply Chain Security: Improve security across our CI/CD pipelines, build infrastructure, dependencies, and deployment processes. Help establish secure, reliable software delivery practices.\n\nVulnerability Management: Own and improve our vulnerability scanning and remediation capabilities, including tooling, automation, prioritization, and integration into engineering workflows.\n\nProduct & SaaS Security: Partner with engineering teams to strengthen application, cloud, and infrastructure security. Help address risks around customer data, access controls, APIs, and third-party integrations.\n\nSecurity Architecture: Lead threat modeling and security reviews for critical systems, helping teams identify risks and make sound architectural decisions.\n\nAI Security: Explore how emerging AI capabilities, including tools and models such as Daybreak and Mythos, can improve security engineering. Help teams understand and address risks introduced by AI-assisted development, agents, and LLM integrations.\n\nSecurity Strategy: Partner with engineering leadership to identify gaps, prioritize improvements, and establish practical security standards and processes.\n\nTechnical Leadership: Own security initiatives from design through implementation, influence technical decisions, and help build security expertise across engineering.\n\nWhat We're Looking For\nStrong engineering background in software, platform, infrastructure, or security engineering, with hands-on experience building and operating complex systems.\n\nSolid security fundamentals and practical experience improving security in software development, cloud infrastructure, or production environments.\n\nExperience with software delivery security, including CI/CD, vulnerability management, supply chain security, or related areas.\n\nUnderstanding of SaaS security, including the challenges of protecting customer data, securing applications, and operating cloud-based services.\n\nAI-forward mindset, with an interest in emerging AI security capabilities and an understanding of the opportunities and risks AI introduces.\n\nTechnical leadership and ownership, with the ability to drive complex initiatives, collaborate across teams, and balance security with engineering needs.\n\nExperience That Would Be Valuable\nWe don't expect experience in all these areas, but familiarity with some would be helpful:\nSoftware supply chain security, including SLSA, SBOMs, artifact signing, or build provenance.\n\nSecurity scanning and remediation tooling, including SAST, SCA, and container scanning.\n\nCloud-native security, particularly AWS and Kubernetes.\n\nThreat modeling, application security, identity, or secrets management.\n\nAI-powered security tooling and securing AI-assisted development workflows.\n\nBuilding or improving security engineering practices in a growing organization.\n\nWhat Success Looks Like\nYou'll help us build a stronger, more scalable approach to engineering security.\nIn your first year, you'll identify and prioritize meaningful risks, improve our software supply chain and vulnerability management capabilities, and establish security practices that fit naturally into how our teams build and operate software.\nYou'll bring the technical expertise, ownership, and judgment to make measurable improvements while helping security become a shared responsibility across engineering.\nInterview process\nWe'll share a detailed interview plan with you on the intro call. The loop is designed to mirror the actual job: real artifacts to react to, conversations that look like the conversations you'd have on the team, and reference checks taken seriously. We'll move quickly when there's mutual fit.\nWhy Work at Aiwyn?\nThe big-picture value proposition of this role is simple: join us, and you'll be paid competitively to have freedom in solving worthwhile, challenging problems alongside other A-players at a fast-growing SaaS startup led by an experienced and successful team with industry experience\n\nAI-by-Default - you'll have access to best-in-class AI tools and work in an environment that embraces an AI-by-default mindset, where curiosity and experimentation are part of how we operate\n\nRemote-first organization\n\nCompetitive compensation and benefits\n\nStock options\n\n401(k) matching\n\nAdventure Travel Stipend on each anniversary of your employment with Aiwyn\n\nOur Values:\nRelentless by Design\n\nOwners not Renters\n\nTrust at the Core\n\nAiwyn is an equal opportunity employer.
