Application Security Engineer

About Valence

Valence has built the only first-to-market AI native coaching platform for enterprise, offering personalized, expert, and human-like guidance and support to any leader or employee. We’re not just talking about the future of work — we’re building it now, with the most innovative Fortune 500 companies across healthcare, financial services, manufacturing, and technology. Our focus is on the problems that actually decide whether AI changes how organizations operate — the ones with no playbook, no obvious answers, and no guarantee of success. If you want to be part of the small group that defines how AI transforms the future at a global scale, this is your chance. And this isn’t for everyone. We’re not looking for people who want predictability or incremental progress. We only want those who are restless at the edge of what’s possible, who get bored when things feel “done,” and who are driven to redefine what AI can mean for leaders, companies, and the world. Because at Valence, the work worth doing is the kind that redefines work itself.

We're the only company pioneering leadership coaching for large enterprises in an AI-first way. Our mission is to transform how the world's biggest companies approach learning and development, helping teams work better together through AI-powered personalization that adapts to individual goals and organizational culture using the latest advances in machine learning and natural language processing. We've been featured in Harvard Business Review, TIME, World Economic Forum, Financial Times, Forbes and an Inc. 5000 fastest-growing private companies in America. Our clients represent the most diverse and sophisticated enterprise AI implementations globally, including Coca-Cola, Delta, Nestlé, General Mills, Schneider Electric, Deutsche Telekom, AstraZeneca, Prudential, CVS and Bristol Myers Squibb. Working at Valence means you'll work directly with Fortune 500 technology leaders, building expertise through the most complex enterprise deployments while gaining insight into diverse organizational approaches to AI transformation. These aren't just any enterprise clients - they're the companies defining what AI-first business transformation looks like across every major industry.

The Role

We are seeking a seasoned Application Security Engineer to help us secure our products and platform that serve our Fortune 500 customers. In this pivotal role, you will be working in close partnership with our engineering teams, ensuring that everything they build holds up to our security standards. While your primary focus will be application security, you are joining a small, elite team, and as such you will also work cross-domain, including working with MDM, or talking with customers directly.

Key Responsibilities

• Stay ahead of engineering: review code, architecture, design, anything that’s being considered for release
• Guide features and designs toward security
• Provide hands-on manual pentesting on relevant code changes
• Build and maintain security tooling to ensure security scales with organisation
• Advise the DevOps team on infrastructure security best practices
• Help out with client-facing security needs, such as client calls

Qualifications

• Proven experience securing products & platforms, collaborating with development teams
• Strong expertise in application security: OWASP Top 10, threat modeling, code reviews, architecture design
• Proficiency with AI tooling, as part of your day-to-day activities
• Solid understanding of AI itself, including AI threats, adversarial testing
• Familiarity with AWS and infrastructure security overall
• Be comfortable writing and reviewing Python and TypeScript, with other coding experience a plus
• Experience with incident response and SOC processes
• Knowledge of compliance frameworks: SOC 2, ISO 27001, NIST
• Experience with enterprise security processes, such as security questionnaires and client calls

We don’t expect candidates to have deep expertise in every area; strength in application security with curiosity and adaptability across adjacent domains is key.
