Platform Engineer
Principal Full Stack Engineer – AI Systems & Engineering Automation

Apply on the employer's siteRole description
Most engineering orgs added AI to their toolbelt and called it transformation. We replaced the toolbelt entirely. Our platform — enterprise community engagement and social media management software trusted by Fortune 100 brands — is built by a lean, senior team whose output rivals teams many times larger, because AI agents do the building and engineers build the system that makes that possible.
We're looking for a Principal Full Stack Engineer who obsesses over engineering leverage: someone who sees a repeatable task and immediately thinks about the scaffolding, context, and evaluation loop that would let an agent handle it permanently. You won't be measured on lines written — you'll be measured on how much of the development lifecycle you've made autonomous, reliable, and shared.
Your Impact
- Design the automation layer. Create and refine the skills, rules, context packages, and self-verification harnesses that enable coding agents to plan, implement, test, and deliver production-quality software with minimal human involvement — and make that involvement trend toward zero over time.
- Run parallel agent operations. Dispatch concurrent workstreams to agent fleets, validate outputs against enterprise-grade criteria, and treat every agent failure as a system-design problem to solve once and permanently.
- Deliver customer-facing features at startup speed. Collaborate shoulder-to-shoulder with product leadership in rapid cycles — a customer insight from a morning call can ship as a polished feature the same day. Velocity is non-negotiable, but so is reliability; these customers stake their brand reputation on our platform.
- Compound gains across the team. Every rule tuned, every eval refined, every context file improved gets packaged and shared — your work lifts the ceiling for every engineer and every agent on the team, not just your own throughput.
- Set technical direction. Scope initiatives, review architecture and PRs, mentor senior engineers, and enforce quality standards. You model the AI-native engineering culture and hold the bar before anything reaches production.
What You Bring
- 5+ years of production full-stack engineering on web-based systems — real depth in both front-end and back-end — with demonstrated experience stepping into tech lead or staff-level roles directing other senior engineers.
- An AI-native operating model. You don't hand-code or pair-program with a chatbot. Your instinct is to build the context, tooling, and guardrails that let agents own work end-to-end, then review and verify the result. You think in systems, not keystrokes.
- Broad, deep tool fluency at the frontier. You're a power user of leading agentic development tools (Claude Code, Cursor, Codex, or peers) — and you actively benchmark new tools and models weekly. Being locked into a single tool is a liability; never having gone deep on any is equally disqualifying.
- Current, nuanced model judgment. You can explain which frontier model to reach for in a given scenario, what changed in the last release cycle, and when to trade capability for cost or latency — because you've tested them yourself.
- Strong product instinct. Hand you a goal and you'll define the solution, ship it polished, and own it through to enterprise release — defensive coding, edge-case handling, security, and automated evaluation included. "Demo works" is never your finish line.
- Cloud & CI/CD ownership. Enough AWS and pipeline experience to stand up, ship, and operate a product solo — no infrastructure hand-offs required.
- Production LLM experience. You've shipped real applications integrating large language models via APIs, prompt engineering, agent pipelines, or automation workflows.
- Model Context Protocol (MCP) — hands-on understanding and prior application.
Bonus Points
- Experience with enterprise social, community, or customer-engagement platforms.
- Contributions — published writing, talks, or open source — in agentic engineering or AI-assisted development.
- Hands-on design of multi-agent orchestration: parallel execution, worktree strategies, or file-based agent coordination.
- A track record of building reusable internal tooling (shared rules, eval frameworks, skill libraries) that measurably accelerated a team's output.
What's In It For You
- Uncapped AI resources. No token budgets, no tool restrictions. If a superior model or configuration exists, the door is open — always.
- Fully remote, async-first, worldwide. Written artifacts over status meetings, deep focus on your own schedule, and a feedback loop fast enough to close the gap between idea and production in hours.
- Outsized influence in a lean team. Weekly outcome cycles, direct access to product leadership, and Fortune 100 customers who feel the impact of your decisions immediately.
- Career-defining skill development. You'll build rare expertise at the intersection of applied AI systems, agent orchestration, and enterprise product engineering — the discipline that compounds fastest as AI capabilities accelerate.
If your career has been building toward this moment — where engineering excellence means designing the system that lets AI deliver, not just delivering yourself — we should talk.
