AI Engineer - 3echo Workspace

Company Overview3echo is a Singapore-based AI company building agent-powered products for businesses across Southeast Asia. We deploy AI agents that do real work — content production, operations, client delivery — measured by business outcomes, not features shipped. Small team, founder-led, fast iteration, paying clients.The RoleYou're an AI Engineer who ships end to end. Not a prompt tinkerer, not a pure backend dev — you sit where the agent workflow, the generative media pipeline, and the client's actual business outcome meet. You'll work directly with the founder in a small, fast team where your code goes to paying clients in days, not quarters.Mid-level: 2–4 years shipping real systems. What matters more than years is that you've built things people use and that Claude is how you work. We're a Claude-native shop: Claude Code is the primary development environment, MCP is the integration layer, and agent skills are how we encode process. One engineer here ships what a team of five ships elsewhere, because the leverage is the tooling. If you're not already working this way, you should be hungry to.What You'll Own1. Agent & Workspace infrastructure- Build and maintain MCP servers, agent skills, and workflow orchestration that power client Workspaces- Encode business rules — budget gates, approval SLAs, credit accounting, sign-off rituals as self-enforcing agent behavior- Automation pipelines in n8n connecting our register, comms, and client channels2. Generative media pipeline- Operate and extend the Studio engine: image generation (gpt-image-2), video generation (Seedance 2.0 via BytePlus), reference-anchored character consistency, take/cut/release pipelines- Cost-aware generation: quota management, credit metering, resolution strategy, provider failover- QA tooling for identity hold, canon compliance, and output quality3. Full-stack product & client delivery- Backend services in Python/FastAPI and TypeScript, Postgres/Supabase, deployed on GCP Cloud Run- Client-facing surfaces in React where the Workspace needs a UI- Forward-deployed work: onboarding client Workspaces, debugging live jobs, turning client feedback into shipped fixes fastOur stackClaude & Claude Code · MCP · n8n · gpt-image-2 · Seedance 2.0 (BytePlus) · Gemini (OpenRouter) · Python/FastAPI · TypeScript/React · Postgres/Supabase · Docker · GCP Cloud Run · on-prem RTX 5090 GPU serversYou don't need to know all of it. You need to be dangerous in most of it within your first month.You've probably done some of this- Shipped an LLM-powered product or agent system to real users (side projects count if they're live)- Built with tool-calling / MCP / function-calling APIs, not just chat completions- Worked with generative image or video APIs and dealt with their failure modes- Owned a backend service in production — deploys, logs, incidents, the unglamorous parts- Ship daily with Claude Code (or equivalent) as your primary environment — you know how to scope tasks for an agent, review its output critically, and get 5–10× throughput from it, not 1.2×- Written system prompts, skills, or MCP tools that made a model reliably do a job — you treat the model as a system to engineer, not a chatbot to talk toHow we hireWe hire on AI DNA: attitude, learning curve, hunger. Certifications and brand-name employers don't move us. A GitHub repo, a live demo, or a story about the hardest thing you shipped moves us a lot. Attitude disqualifies faster than ability qualifies.Part of the interview is watching you work with Claude on a real task. We're not testing whether you can code without AI, we're testing how much more you can do with it.First 90 days — what success looks like- Week 2: shipped your first fix to a live client Workspace- Month 1: own one of the three pillars day-to-day with the founder reviewing, not driving- Month 3: a client outcome (turnaround, first-pass rate, or cost-per-deliverable) measurably improved by something you builtHow to applyEmail [email protected] with:1. A link to something you built (repo, demo, live product)2. Three sentences on the hardest technical problem you've solvedInterested candidates are encouraged to apply via this platform.
