Full-Stack Engineer (Internal Systems)

PST

ASAP

Audien runs on a set of apps it built itself: an order management and CX desk, an AI call scoring platform, retail and warranty portals, a marketing command center, a consumer mobile app, and the data pipelines that feed all of them. The Full-Stack Engineer owns the day to day of this internal software. They keep the apps healthy, extend them as the business changes, and build small new tools when a team needs one. Requests come in through Slack and Linear from CX, sales, marketing and ops, and most changes go from request to production within a day. This is a fast, varied, AI-native role (Claude Code, Cursor), working closely with Audien's technical lead and one other engineer.

Key Responsibilities:

• Maintain and extend several production apps at once: Node/Express APIs, React and Angular frontends, Next.js portals, and a React Native mobile app.
• Pick up requests from CX, sales, marketing, and ops directly, scope them in conversation, and ship. Most changes should go from request to production within a day.
• Write and tune SQL against the warehouse for app features, reporting, and one-off questions from the business.
• Keep data flowing between systems: Shopify, Chargebee, Recharge, Five9, Klaviyo, and the warehouse. Fix integrations when they break and add new ones when a team needs them.
• Build small new tools when there's a gap: a portal, an internal dashboard, an automation, a Slack bot.
• Use Claude Code, Cursor, and similar tools as a core part of the workflow, and help extend the internal AI features already in the apps (call scoring, conversational analytics, LLM-backed automations).
• Review PRs, write clear tickets, and keep the codebase consistent with Audien's written Node and React conventions (small PRs, same-day review, frequent deploys).
• Be reachable during the business day (PST). When an order tool breaks, CX is waiting.

• SQL: non-trivial analytical queries, joins across messy source tables, and enough performance sense not to take down the warehouse (used daily).
• React: production experience building and maintaining component-based frontends, including TypeScript.
• Node: production experience building and maintaining Node/Express (or similar) backends and REST APIs.
• AI-native workflow: already uses Claude Code, Cursor, or Copilot to write, refactor, and debug, and knows when to trust them and when not to.
• Fast turnaround on a real codebase: has shipped fixes and features to production the same day they were requested, more than once, in code they didn't originally write.
• Context switching: can hold four or five unrelated things in flight, drop one for a fire, and pick it back up without losing the thread.
• Self starter: asks the business what they need, figures out the rest, and doesn't wait for a fully written spec.
• Clear written communication: most stakeholder interaction happens in Slack and Linear, so they need to be understood by non-engineers.

• Snowflake or another cloud warehouse, plus Fivetran, dbt, or reverse ETL patterns.
• Next.js and Vercel.
• Angular (one core app is Angular; the candidate doesn't need to love it, just be willing to work in it).
• React Native or Expo.
• Shopify Plus, Chargebee, or Recharge integrations.
• CX and contact center platforms such as Five9 or Kustomer.
• Klaviyo or similar marketing platforms.
• Building LLM features into products: Anthropic or OpenAI APIs, tool use, RAG, natural language to SQL.
• Omni, Looker, or a similar BI tool.
• Azure or GitHub Actions for deployment.

• Frontend: React, TypeScript, Next.js, Angular (one legacy app), React Native/Expo
• Backend: Node, Express, native fetch, REST APIs
• Data: Snowflake, Fivetran, Omni, reverse ETL into operational tools
• Commerce and CX: Shopify Plus, Chargebee, Recharge, Five9, Klaviyo
• Hosting and CI: Vercel, Azure, GitHub Actions
• AI: Claude Code and Cursor for development; Anthropic and OpenAI APIs in product
• Coordination: Slack, Linear, GitHub PRs
