📋 Description

• Own threat modeling across our core platform APIs, risk decisioning and event-ingestion systems, and agentic AI products; harden multi-tenant isolation and data-handling across designs and PRs. • Design, implement, and deploy authentication, authorization (user and API), and RBAC across our platform: own and propose new approaches as we scale • Stand up our AppSec program from the ground up: SAST (Semgrep), SCA (Dependabot/Snyk), secret scanning, IaC scanning, and container scanning on Pulumi + EKS • Build guardrails around LLM usage — prompt-injection defenses, output validation, and cost and abuse monitoring on Bedrock/Anthropic/OpenAI calls • Drive security incident process, vulnerability triage, and the responsible-disclosure workflow • Write SECURITY.md, maintain a threat registry, and champion secure-by-default patterns across the engineering org • Partner with IT on shared areas — incident response across corporate and product, access reviews, and audit evidence collection • Collaborate with product and engineering teams on feature design, embedding security early rather than gating at the end • Keep us aligned with current security standards and trends (OWASP, MITRE ATT&CK, and emerging LLM/agent security guidance)

🎯 Requirements

• Strong software engineering fundamentals — 5+ years building software, with the last 3+ focused on application or product security, ideally at a fintech or data-heavy SaaS company • Strong hands-on Java and/or Python code review skills — you're comfortable in a PR, not just in a report • Experience with SSO, SAML, OAuth 2.0, JWT, mTLS, and JOSE; multi-tenant authZ; PII handling/tokenization • Working knowledge of AWS security primitives (IAM, KMS, Secrets Manager, VPC) and Kubernetes

🏖️ Benefits

• 100% of your Medical/Dental (Care Plus) for you and your dependents • 100% Life / LTD (Prudential) • Caju Card for monthly meal allowance • Remote first culture. • Family-Friendly environment; Regular team events and offsites. • Unparalleled learning and professional development opportunities. • Making the internet safer by protecting online transactions.
