About Trajan Wealth

About Trajan Wealth

With over $3 billion in assets under management and advisement, Trajan® Wealth is one of the fastest-growing Registered Investment Advisor firms in the country.

What sets us apart is our fully integrated, in-house model - combining fee-only wealth management, estate planning through Trajan Estate, and tax strategy through Trajan Tax.

We don't refer out critical components of a client's financial life. We bring them together under one fiduciary standard - the Family Office.

Role Overview

We are seeking a Senior Full Stack Engineer with deep API management experience to help build, scale, and secure the digital platforms that power our financial services products. You will work across the stack, from designing customer-facing web experiences to architecting the API gateway, authentication, and integration layer that connects our internal systems, partner banks, and third-party data providers.

This role sits at the intersection of product velocity and platform reliability. You will partner with product managers, designers, security, compliance, and SRE teams to deliver features that meet the regulatory bar of financial services while still moving at the pace our customers expect. Your work will directly influence how the firm exposes capabilities to internal teams, fintech partners, and end clients.

This role would be 100% onsite at our Scottsdale corporate headquarters.

How We Work

• Small, autonomous product squads with clear ownership and meaningful end-to-end scope.
• Trunk-based development, CI/CD, and a culture that prefers small, reversible changes over large, risky releases.
• Genuine investment in engineering quality: paved roads for common patterns, internal platform teams to lean on, and time set aside for tech debt and learning.
• Blameless incident culture, with the expectation that postmortems lead to real change.

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

Required:

• 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.).
• Direct experience with a commercial or open-source API management platform (MuleSoft, AWS API Gateway, Azure API Management or similar).
• 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.

Benefits

• $108,000 to $140,000 base salary plus bonus
• 401(k) with a matching contribution up to 13%.
• United Healthcare PPO medical coverage for employees, paid by the company.
• Delta Dental PPO, United Healthcare Vision, Short Term Disability, Long Term Disability, Life Insurance, and many more voluntary options.
• Generous holidays and PTO.
• Future career growth opportunity.
