Trajan Wealth LLC · Scottsdale, AZ · 2 wk ago
EngineeringFull-time
Duties And Responsibilities
- Design, build, and operate full-stack features end-to-end - from React/TypeScript front ends, through Node.js / Java / Python (or similar) backend services, to data persistence and event-driven integrations.
- Own the API lifecycle: design RESTful and event-driven APIs, manage versioning, deprecation, and backward compatibility, and curate the developer experience through OpenAPI/Swagger documentation and SDKs.
- Configure and tune our API gateway platform (MuleSoft).
- Implement and maintain authentication and authorization patterns appropriate for financial services: OAuth 2.0, OIDC, mTLS, JWT validation, scoped access tokens, and consent management for open-banking-style flows.
- Partner with security and compliance to ensure all systems meet relevant standards (e.g., SOC 2, PCI DSS, GLBA, GDPR / CCPA, SOX where applicable) and pass internal audits and external regulatory reviews.
- Build observability into everything: structured logging, distributed tracing, metrics, alerting on golden signals (latency, traffic, errors, saturation), and meaningful SLOs for the services you own.
- Write production-quality, well-tested code, and uphold engineering standards through thoughtful code review, pairing, and mentorship of mid-level engineers.
- Participate in an on-call rotation for the services you own, drive incident response when issues arise, and lead blameless postmortems that translate into durable system improvements.
- Collaborate with product to translate business and regulatory requirements into clean technical designs, and be a credible voice in trade-off conversations around scope, risk, and timeline.
Qualifications
- 5+ years of professional software engineering experience, with meaningful time spent on both frontend and backend systems.
- Strong proficiency in a modern frontend framework (React preferred; Vue or Angular acceptable) with TypeScript, and in at least one backend language commonly used in financial services (Java, Python, Go, Node.js, or C#).
- Working knowledge of Dagster (or a comparable orchestration framework such as Airflow or Prefect) and Snowflake, including building data pipelines, modeling warehouse data, and integrating analytical workloads with operational APIs.
- Hands-on experience designing and operating APIs in production at scale, including REST and ideally one of GraphQL, gRPC, or event-driven (Kafka, EventBridge, etc.).
- Solid grounding in identity and access standards: OAuth 2.0, OIDC, JWT, mTLS, and API key management.
- Cloud experience on AWS, Azure, or GCP, including containers (Docker), orchestration (Kubernetes or ECS).
- Working knowledge of relational and at least one non-relational database, and comfort reasoning about data consistency, transactions, and idempotency in financial workflows.
- Demonstrated ability to ship in regulated environments, comfortable with code reviews, change management, audit trails, and the discipline that financial services demands.
- Clear written and verbal communication; ability to explain technical concepts to product, business, and non-technical stakeholders.
Nice To Have
- Experience integrating with core banking platforms, payment rails (ACH, SWIFT, FedNow, card networks), market data providers, or KYC/AML vendors.
- Familiarity with open banking standards (FDX in the US, PSD2 / Open Banking in the UK/EU) and consent-driven data sharing patterns.
- Exposure to financial-grade API security profiles (FAPI) and mutual TLS in production.
- Experience contributing to a developer portal, internal API marketplace, or platform-as-a-product model.
- Background working with event sourcing, CQRS, or ledger-style data models.
- Prior experience as an on-call leader or as the engineering point of contact during incidents impacting regulated services.
