Job description
ServiceLink is modernizing the mortgage services industry through AI‑accelerated engineering, intelligent automation, and next‑generation software delivery practices. We empower the nation’s top lenders and financial institutions with advanced technology, data‑driven insights, and high‑velocity product development models.
We’re not just evolving legacy workflows - we’re redefining how software is designed, built, tested, and deployed. Generative AI, autonomous systems, and continuous delivery are core to how we operate. Innovation isn’t optional here - it’s the expectation.
If you’re passionate about transforming engineering organizations and operationalizing AI‑driven development models at enterprise scale, you’ll thrive at ServiceLink.
About the Role
We need a builder‑leader who combines strong architecture judgment with hands‑on execution. This role owns the secure architecture direction for a large, cloud‑native financial services platform on Azure handling sensitive customer data and is expected to personally implement key controls while leading others to scale.
Success means reducing real risk in production systems through shipped controls, faster secure delivery, and measurable coverage improvements.
50% hands‑on engineering: build reference implementations, improve pipelines, validate controls in real services
30% technical leadership: architecture decisions, threat modeling, secure design reviews, backlog direction
20% enablement and communication: standards, coaching, leadership reporting, audit‑ready evidence
Outcomes You Own
Secure‑by‑default patterns are adopted across .NET, Python, and SPA services
High‑risk authN/authZ and PII exposure paths are identified and remediated
Identity‑first service‑to‑service architecture is operationalized (managed identities, token patterns, least privilege)
Security testing and policy checks are integrated into CI/CD with clear ownership and SLAs
Security posture is measurable with trendable metrics, not one‑time reports
What You'll Do
Build and publish production‑ready security reference architectures and reusable templates
Lead threat modeling and design reviews for new and materially changed services
Own RBAC and authorization architecture, including endpoint‑to‑data classification and least‑privilege mapping
Design and drive managed identity adoption for SQL, Cosmos DB, and service‑to‑service communication
Implement container and Kubernetes hardening controls, including image trust, patch cadence, and egress guardrails
Evaluate and tune SAST, SCA, DAST, IaC, container, and secret scanning against real codebases and deployment patterns
Define AI/LLM security guardrails, including prompt‑injection defenses, model/data access controls, and safe‑use patterns for engineering teams
Lead chaos engineering exercises to validate security controls and resilience under failure and attack scenarios
Define risk‑based security gates in Azure DevOps and partner with engineering on pragmatic exception handling
Convert third‑party pen test and internal findings into durable engineering fixes and regression checks
Mentor engineers and junior security staff through design pairing, code review, and incident retrospectives
Present architecture decisions, risks, and remediation progress to technical and executive stakeholders
Publish a target‑state application security architecture with prioritized implementation roadmap
Deliver two reference implementations (one API service, one data‑access service) showing secure patterns end‑to‑end
Stand up baseline threat‑model workflow for all tier‑1 services with tracked remediation outcomes
Define and launch security scorecard metrics (coverage, MTTR, policy exceptions, high‑risk exposure trends)
Complete toolchain fit assessment with keep/replace recommendations and rollout plan
Must‑Have Qualifications
7+ years in application security, security engineering, or software engineering with significant security architecture ownership
Proven delivery in cloud‑native Azure environments (AKS, App Services, Entra ID, Managed Identities)
Deep experience with microservice/API security, authentication/authorization, secrets management, and data protection
Strong practical threat modeling and secure design review experience tied to shipped outcomes
Hands‑on experience integrating security controls into CI/CD workflows (Azure DevOps preferred)
Ability to code and review implementation quality in at least one major backend stack (.NET or Python preferred)
Demonstrated ability to drive cross‑team adoption, resolve trade‑offs, and deliver under business constraints
Nice‑to‑Have Qualifications
Financial services or similarly regulated environment experience
Kubernetes network policy and runtime hardening depth
Experience building security metrics programs and engineering SLAs
Background partnering with offensive security and incident response teams
What Good Looks Like (12 Months)
Material reduction in overall findings
Consistent security controls across new services by default, with fewer one‑off exceptions
Clear, trusted security metrics used in engineering and leadership planning
