Software Engineer

Organization / Role Description: As a member of the Enterprise Middleware and Online Security Technology team, this role is designed for a strong independent engineer who can own complex features, contribute to design decisions, and deliver secure, scalable authentication capabilities. The successful candidate will help build and support enterprise web applications and modern authentication journeys, including Passwordless Login and Risk Based Authentication. This role requires strong engineering judgment, production support discipline, and the ability to partner with product, security, fraud, risk, architecture, and platform stakeholders. This role also requires practical use of AI-assisted engineering workflows across the software development lifecycle, including GenAI coding assistants, structured prompts, validation practices, and emerging agentic development patterns to improve delivery efficiency, quality, testing, troubleshooting, and documentation while maintaining strong engineering ownership.

Own design, development, testing, and support for complex application components and secure authentication capabilities.

- Partner with product owners, SCRUM masters, architects, and engineers to decompose features, estimate delivery effort, and meet sprint and release commitments.

- Design and implement secure, resilient, user-friendly authentication journeys using risk signals, telemetry, and policy-based decisioning.

- Contribute to Passwordless Login, FIDO2/WebAuthn/passkey, Risk Based Authentication, and modern identity solutions.

- Build and consume REST APIs, gateway patterns, and reusable services that align with platform principles and architectural standards.

- Maintain high standards for automated testing, CI/CD, code quality, security scanning, observability, and release readiness.

- Troubleshoot high-stress and time-critical production situations with strong ownership and sound technical judgment.

- Mentor less-experienced engineers through code reviews, design discussions, and knowledge sharing.

- Use AI-assisted engineering tools across day-to-day SDLC activities, including implementation, refactoring, unit testing, regression support, code review preparation, scripting, troubleshooting, and documentation.

- Apply agentic and spec-driven development practices by converting design inputs such as API contracts, data models, class structures, and integration details into structured prompts or specifications that support AI-assisted implementation.

- Validate AI-generated recommendations, code, tests, and documentation using strong engineering judgment, secure coding practices, and established team quality standards.

- Share practical learnings with peers on effective prompt usage, custom instructions, and responsible AI-assisted development patterns.

Experience designing or implementing Passwordless Login, FIDO2/WebAuthn/passkeys, or modern authentication journeys.

- Experience with Risk Based Authentication concepts including risk scoring, step-up authentication, device signals, behavioral signals, and policy-based access decisions.

- Experience deploying containerized applications to Google Cloud Platform, AWS, or similar cloud platforms.

- Experience with GitHub Actions, Bamboo, Sonar, Blackduck, Veracode, or similar CI/CD and code security tooling.

- Familiarity with NIST identity standards and financial services technology environments.

- Performance testing or performance engineering experience.

- Experience applying AI-assisted development practices to improve delivery velocity, test coverage, troubleshooting efficiency, documentation quality, or developer productivity.

- Exposure to Large Language Models or AI-enabled engineering workflows in enterprise, regulated, or security-sensitive technology environments.
