Requirements

TypeScript and React (Non-Negotiable)

  • 5+ years of professional React development; 3+ years using TypeScript in a production React codebase not just annotating JS, but designing typed data contracts, discriminated unions, and generic component interfaces.
  • Strong understanding of React 18 patterns: functional components, custom hooks, memo/useCallback usage, Suspense and lazy loading.
  • Practical experience with Redux Toolkit and RTK Query: defining API slices, managing loading/error states, understanding caching and cache invalidation behavior. Experience with Redux middleware or Thunks is useful but secondary to RTK Query fluency.
  • Form handling with react-hook-form and schema-based validation (Yup or Zod). Comfort with multi-step forms, conditional field logic, and controlled vs. uncontrolled patterns.
  • Familiarity with design system libraries coupled with the ability to read component documentation and use the provided components correctly without reaching for custom solutions.

Node.js API Development:

  • 3+ years building and maintaining REST APIs with Node.js and Express (or equivalent framework). The ability to design endpoint shapes that are efficient to consume from the client and that handle partial failures gracefully.
  • Experience integrating with external APIs or SaaS platforms writing against third-party REST or SOAP interfaces, handling pagination, rate limiting, and API version differences.
  • Working knowledge of authentication middleware: JWT validation, token refresh patterns, understanding of OAuth 2.0 / OIDC flows even if you have not built them from scratch.
  • Comfort with Redis for caching: setting TTLs, invalidation strategies, understanding when caching introduces staleness risk.

Testing Discipline:

  • Writes tests as part of implementation, not after. Can articulate the difference between testing behavior and testing implementation details.
  • Experience with React Testing Library (or equivalent) tests that simulate user interactions and assert on visible output, not on component internals.
  • Able to write meaningful tests for async behavior (loading states, API responses, error boundaries) using mocked service layers.

Communication and Collaboration

  • Comfortable working from incomplete specifications. This codebase has documented open questions and known design ambiguities. You should be able to make reasonable implementation decisions while flagging assumptions clearly, rather than blocking on every undefined detail.
  • Can write clearly about technical decisions not lengthy documents, but precise comments, PR descriptions, and notes that explain why a non-obvious choice was made.
  • Experience working in a two-week sprint cadence with regular demos and code review.

Preferred Experience:

  • The items below are meaningful advantages, not requirements. Strong candidates who lack one or two of these areas but demonstrate strong fundamentals will be considered.

Salesforce Integration

  • Experience querying Salesforce APIs REST, SOQL, or the Composite REST API from a Node.js service layer. Familiarity with Salesforce object relationships, governor limits, and the operational constraints of building against a shared Salesforce org. This is the hardest skill to hire for and the one most directly relevant to the near-term work candidates with it will ramp faster on the Salesforce integration stories.

Salesforce Financial Services Cloud (FSC)

  • Awareness of FSC-specific objects (Financial Account, Financial Account Party, Financial Account Transaction) and the patterns around financial planning data in Salesforce. This is uncommon and not expected; it is worth calling out because it maps directly to the data model being built against.

Configuration-Driven UI Patterns

  • Experience building UIs where behavior (form fields, visible actions, permission rules) is driven by JSON configuration or metadata rather than hardcoded logic. This pattern is central to how the Plan Actions dropdown and form workflows are architected in this codebase.

Authentication and Identity

  • Production experience with Okta specifically the Okta React SDK and its interaction with protected routes, token management, and user profile claims. Understanding of how identity provider tokens flow through to API authorization.

Event-Driven Systems

  • Exposure to Apache Kafka or a comparable message broker consuming events from a topic, understanding at-least-once delivery, schema registry basics. Kafka is used for plan status notifications and data synchronization in this system; most of the Plan Detail work does not touch it directly, but familiarity is useful for understanding the broader system.

Financial Services Domain

  • Understanding of concepts like financial plan administration, fee allocation, advisor-client relationships, or fiduciary workflows. Domain knowledge reduces the time required to understand why certain data models exist and what edge cases matter to users. It is not expected but meaningfully shortens onboarding.

Python API Development

  • Production experience building REST APIs in Python using FastAPI, Flask, or Django REST Framework. Comfort with async patterns (async/await in FastAPI or equivalent), request validation, and structuring a Python service for maintainability alongside a Node.js-heavy ecosystem.

Data Manipulation and ETL

  • Hands-on experience using Python for data transformation work pandas, SQLAlchemy, or similar libraries particularly in the context of moving or reshaping data between systems (ETL pipelines, data migration scripts, or integration utilities). Familiarity with writing repeatable, auditable data workflows is a plus given the system-of-record nature of the platform.

Accessibility

  • Working knowledge of WCAG 2.1 AA compliance aria attributes, keyboard navigation, screen reader behavior. Blueprint components handle much of this, but custom compositions still require accessibility-aware implementation.
