Security Engineer

Location: Remote (Must accommodate US East Coast working hours).

About Us

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 They drive 30-50% of company revenue, yet most partner teams are stuck with spreadsheets, email chains, and outdated CRMs.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

Role Overview

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.

You will review our platform end to end, from data access and backend services to APIs, integrations, and our AI layer. You will 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.

What We're Looking For

• 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.

Why Join Us

• 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.

We'd love to meet you.
