About the Role:

Constellation Payment

Processing is a modern Payment Facilitator (PayFac) empowering SaaS businesses to grow revenue through seamless, embedded payments. As part of Constellation Software Inc. (TSE:CSU) — a global Canadian-based software leader at a $96B market cap and the 7th largest software company in the world — we combine the agility of a specialized payments company with the strength and stability of an established global powerhouse.

We're building a cloud-native PayFac platform on AWS: microservices (DDD) across TypeScript/JavaScript, Java, and Ruby, with a ReactJS front end. As our Security Engineer, you'll co-own the DevSecOps program—driving continuous security automation, compliance automation, and penetration testing. You'll design and orchestrate SAST/SCA/DAST across our services, champion remediation practices, and partner closely with our compliance team to translate control objectives into repeatable, automated evidence.

Our customers are ISV vendors who embed payments by integrating with our APIs, SDKs, and webhooks. That means security and compliance aren't afterthoughts—they're product features. You'll ensure our developer-facing surface area is secure by default: establishing standards for authentication and authorization (OIDC/OAuth2/JWT, mTLS/JWS for webhooks), key and secret management, request signing, idempotency, rate-limiting/abuse controls, and secure data handling that minimizes PCI scope for ISVs (tokenization, hosted fields/iframes, PAN vault boundaries, network tokens). You'll create secure integration patterns (reference apps, checklists, threat models/DFDs) so partners can implement quickly without compromising controls.

Because we operate a multi-tenant PayFac, you'll harden isolation boundaries (network, identity, and data), lead supply-chain security (SBOMs, signing/provenance, gated deployments), and build continuous evidence for PCI DSS 4.0 (and SOC 2/ISO as needed). You'll collaborate with partner security and compliance teams on due-diligence requests (SIG Lite, AOC/ROCs, shared-responsibility matrices), and you'll own pre-launch security reviews for new ISV integrations. You'll also help run incident response drills and define partner-facing comms and SLAs for security events.

Finally, you'll research and implement AI-assisted security (triage, anomaly detection, auto-remediation PRs) with appropriate guardrails, and own KPIs that demonstrate multiplier effects—e.g., reduced MTTR, lower false-positive rates, higher auto-triage coverage, and faster time-to-evidence—so our platform's security posture continuously improves as our ISV ecosystem scales.

What You'll Do:

Own Security Automation:

• Design, implement, and run the CI/CD security toolchain: SAST, SCA, DAST, container and IaC scanning, secrets detection, SBOM generation, and policy-as-code.
• Integrate scanners into GitHub/GitHub Actions pipelines with PR gates, and auto-ticketing to JIRA; tune noise, baselines, and break-glass rules.
• Establish vulnerability management SLAs, risk acceptance workflow, and metrics dashboards (e.g., MTTR, vuln burn-down).

Embed Security in the SDLC:

• Create lightweight secure-coding standards and review checklists for TypeScript/Node, Java, Ruby, React.
• Run threat modeling (STRIDE/PASTA) and produce DFDs (L0–L2) for new and high-risk flows.
• Lead a "security champions" program with engineering squads.

Platform & Cloud Security (AWS/EKS):

• Harden EKS workloads (admission controls, pod security, image signing, runtime protection), ECR scanning, and supply-chain security.
• Implement and iterate on IAM least-privilege, KMS/CloudHSM key management, network segmentation, WAF/Shield, CloudFront, GuardDuty/Security Hub, and centralized logging.
• Validate service-to-service auth (mTLS, OIDC, JWT), secrets management (AWS Secrets Manager/SSM), and data protection at rest/in transit (FIPSvalidated crypto).
• Manage security certificate adoption our own and 3rd party across the company technology stack

Compliance Automation:

• Map controls and automate evidence for PCI DSS 4.0 (and SOC 2/ISO 27001 as needed): continuous monitoring, detector-to-control mappings, and audit-ready artifacts.
• Partner with compliance on policies, risk register, third-party/vendor assessments, and control testing cadence.

Penetration Testing & Response:

• Scope and coordinate internal and third-party penetration tests (API, web, mobile, cloud); plan fix-verification and retests.
• Contribute to incident response playbooks, tabletop exercises, and forensics runbooks.
• Participate in incident response events and be a key contributor on improving security posture

Research & implement AI security tools:

• Evaluate and deploy AI/ML capabilities (LLM-assisted code reviews, AI triage for SAST/SCA/DAST, anomaly detection over logs/telemetry, drift detection) to reduce toil and increase signal quality—without leaking sensitive code or data.

Own outcomes & KPIs:

• Define baselines, instrument dashboards, and continuously tune models/policies to demonstrably improve detection efficacy, remediation speed, and compliance evidence quality.

Guardrails & governance:

• Establish safe-use patterns (PII redaction, repository allowlists, prompt/content controls, human-in-the-loop), document model/feature risks, and keep audit trails that map to PCI DSS 4.0 controls.

Automation & SOAR integration:

• Orchestrate AI-assisted enrichment and response (e.g., auto-labeling, deduplication, prioritization, suggested fixes/PRs) across CI/CD, SIEM, ticketing, and chat.

KPIs You'll Own:

• MTTR for high-severity vulns/incidents: 40–60% vs. baseline within 2–3 quarters.
• Alert noise reduction (precision/FP rate): 50% reduction in false positives on gated scans and detections.
• Auto-triage coverage: 70% of scanner findings enriched and prioritized by AI with reviewer acceptance 90%.
• AI-generated remediation PRs: 30% of low/medium issues fixed via assisted PRs passing CI policy.
• Time-to-evidence (PCI 4.0 controls): 50% for recurring audits via automated control artifacts.
• Signed-off service coverage: 90% of services covered by AI-backed detections and scan triage.

What You'll Bring:

• 8–10 years in application/cloud security or DevSecOps for high-availability platforms (fintech/payments ideal).
• Hands-on DevSecOps program administration experience with Veracode.
• Fluent in Terraform for the AWS Stack
• Strong CI/CD experience (GitHub Actions preferred) and automation in Python/TypeScript/Bash.
• Solid AWS security fundamentals: IAM, KMS, CloudTrail, Config, Security Hub, GuardDuty, VPC/LBs, WAF/Shield; Kubernetes/EKS hardening experience.
• Familiarity with microservices, event-driven systems, and DDD; ability to read code in TypeScript/Java/Ruby and basic ReactJS patterns.
• Working knowledge of PCI DSS 4.0 control objectives (tokenization/PAN handling, key management, segmentation, logging/retention), plus SOC 2/ISO 27001 concepts.
• Clear communication with engineers and non-technical stakeholders; bias to automate and simplify.
• Bonus Point: Payments domain exposure: EMV/3DS, PAN vaulting, network tokenization, P2PE, dispute/chargeback flows.

How We'll Measure Success:

• 90 days: Security scans embedded in CI for core services with actionable findings; baseline metrics and SLAs defined; initial PCI 4.0 control mappings complete.
• 6 months: False-positive rate <10% on gating scans; P1/P2 MTTR within SLA; SBOMs & dependency policies enforced; security champions running.
• 12 months: Compliance evidence automation covers priority controls; successful third-party penetration test with timely remediation; measurable reduction in highrisk vulns and misconfigurations.

Team & Reporting:

This role sits in the CTO organization (Engineering/Platform) and partners daily with compliance, DevOps/SRE, Backend/Frontend teams, and Product.

Our Stack (you don't need all of these):

AWS (EKS, ECR, KMS, CloudHSM, WAF/Shield, CloudFront, GuardDuty, Security Hub,

CloudWatch), GitHub/GitHub Actions, Terraform, Node/TypeScript, Java, Ruby, React,

Kafka, MongoDB, Postgres, Redis, Veracode, OWASP ZAP/Burp, AI Tools in Microsoft Teams, JIRA, Development IDEs (Amazon Q, Cursor, Claude Code)
