Job Summary

You own customer and business outcomes, not tickets. You work like a forward-deployed engineer: based at the hub, you embed into a pod or team where the problem is, ship the outcome across the full stack (Elixir backend, Vue frontend), then carry what you learned back so the next team moves faster. The technical bar is high, but coding ability is the floor here, not the ceiling. What sets this role apart is judgment: knowing the smallest thing worth shipping, when to kill your own idea, and when AI output is good enough versus when to override it.

You'll move between the hub and the teams you embed with, shipping early, talking to customers, and deciding fast.

Responsibilities:

• Own outcomes end-to-end, wherever you're deployed. Frame the problem, design it, ship it, own the metric. Descope to the cheapest version that works. Prototype in days.
• Stay close to customers. Shadow sales and support, join advisory conversations, and let customer reality drive technical decisions. Propose what to build, defer, and kill.
• Own your domain and share it. Its interfaces, reliability, performance, and security, including on-call for the systems you own. Consent and PII handling are central to customer trust. Bring patterns, tooling, and hard-won context back to the wider org rather than hoarding them.
• Architect AI-driven leverage. Build AI-assisted workflows that hold up, evolve the team's practices as tooling changes, and look for product wins AI unlocks (smarter routing, anomaly detection, and more).
• Multiply the teams you touch. Mentor on judgment and product sense, not just syntax. Write decision memos and ADRs. Enable Product and Design to self-serve.

Qualifications and Skills

• A track record of shipping something end-to-end that you cared about and owning the outcome, not just the code.
• Product judgment: pushing back on a bad spec, proposing the cheapest experiment, and descoping well.
• Comfort embedding with unfamiliar teams and codebases, getting productive fast, and leaving them better than you found them.
• Deep full-stack expertise: Elixir, Vue 3 / Nuxt, Postgres at scale, AWS (Kubernetes a plus). Node.js a bonus.
• Strong systems design judgment in ambiguous contexts, and a security mindset aligned with sensitive consumer data and compliance.
• Fluency reading AI output critically and building your own AI-assisted workflows.
• Clear written and verbal communication. Mentorship experience. 5-10% travel.

How It Works

You'll report to an Engineering Manager who owns several teams and stays out of their daily flow. As you embed, you'll often act as the player-coach Tech Lead, owning technical direction while the EM owns delivery health and stakeholder alignment across the group.

Success looks like movement in a user or business metric you/your team owns, high-value work deliberately not built, decisions made fast, and teams that move faster after you've worked with them, not just while you're there.
