[Hiring] Security Engineer @EULER

Role Description

As our Security Engineer, you will own the security of EULER's applications: making sure we follow sound security practices and that our platform keeps pace with current security standards.

• Review our platform end to end, from data access and backend services to APIs, integrations, and our AI layer.
• Identify risks, explain them clearly, and recommend how to address them.
• Most fixes will be carried out by our engineering team with your guidance; some you will make yourself.

Key Responsibilities

• Identify risks.
• Run security reviews, code and configuration audits, and penetration tests across our applications, APIs, and integrations.
• Secure our AI layer.
• Assess our AI agents and their integrations for prompt injection, excessive permissions, and unauthorized data access.
• Recommend and prioritize fixes.
• Turn findings into clear recommendations for the engineering team, and implement fixes yourself where it makes sense.
• Set and update the standard.
• Define secure development practices and keep them current as new threats and standards emerge.
• Use AI-driven security tooling.
• Run open-source, agent-based security tools for continuous testing, and verify what they report.
• Support customers.
• Join calls with customers' security teams and help answer technical security reviews.

Qualifications

• 4+ years in application security, product security, or security-focused software engineering.
• Hands-on experience finding vulnerabilities in web applications and APIs (OWASP Top 10, access control, authentication, OAuth).
• Solid knowledge of AI and LLM security, including prompt injection and agent permission design.
• Experience using AI-agent-based security tools.
• Ability to read code in JavaScript/TypeScript and Python, and to write fixes when needed.
• Strong written and spoken English, and comfort presenting on customer calls.

Nice to Have

• Experience with Bubble.io or other low-code platforms.
• Experience securing MCP servers or other agent-to-tool integrations.
• Experience with Cloudflare and AWS.
• Security certifications (OSCP, OSWE, BSCP, or similar), bug bounty record, or CVEs.

What Will Not Work Here

• Handing over raw scanner output instead of verified, prioritized findings.
• Treating security as a gate that blocks shipping instead of helping the team ship safely.
• Trusting AI tooling output without checking it.

Benefits

• Own security on a B2B platform with AI agents at its core.
• Work on AI security in a product where agents act on behalf of users every day.
• A profitable, fast-growing SaaS company with enterprise customers.
• Competitive salary, no ego, full ownership.

Company Description

Partnerships are the future of go-to-market. They drive 30-50% of company revenue, yet most partner teams are stuck with spreadsheets, email chains, and outdated CRMs.

EULER is the AI-native PRM changing that, and we grew 600% last year doing it. We are not iterating on legacy PRM software. We are redefining what the category is.
