The Role
As a Senior AI Platform Engineer, you'll be on the frontlines of our most critical customer implementations, building the production software that powers AI Employees deployed in real business environments.
You'll design, build, and deliver the core software foundations — services, data models, and CRUD applications — plus reliable integrations with external systems. On top of that foundation, you'll build agentic and conversational AI systems that handle live users, multi-turn conversations, real-time constraints, and complex workflows. These are not demos or experiments — they are production systems that customers rely on.
Beyond hands-on engineering, you will act as a technical owner for client delivery. You'll translate customer requirements and SOWs into working systems, own delivery timelines, manage technical tradeoffs, and ensure successful outcomes in production.
This is a hands-on role. You're not just reviewing PRs or sitting in meetings — you're building, debugging, and shipping, while raising the engineering bar through crisp technical judgment and strong ownership.
Responsibilities
- Build production software with code and Supernal's proprietary platform, including backend services, data models, and CRUD applications
- Build and maintain integrations with external systems (APIs, webhooks, third-party tools, and data sources) that AI Employees can safely act on
- Design, implement, and deploy conversational agents, including multi-turn flows, state management, and tool usage
- Own end-to-end technical delivery for high-priority customer implementations, from architecture through production launch
- Translate customer requirements and SOWs into clear technical designs, execution plans, and deliverables
- Make and own architectural decisions across application design, API integrations, LLM orchestration, RAG design, and workflow decomposition
- Handle real-world voice system challenges including latency, interruptions, fallbacks, error handling, and failure recovery
- Write automated tests — unit tests for isolated logic and end-to-end tests for full system and user journey validation
- Apply solid error handling: distinguish retryable vs. fatal failures, surface meaningful error messages, and avoid silent failures
- Actively debug complex production issues across agent logic, prompts, integrations, and external dependencies
- Partner with delivery and product leadership to manage timelines, scope, and technical tradeoffs during implementation
- Review technical work for quality, scalability, and maintainability, setting a high bar for engineering excellence
- Define, document, and evolve best practices for building and delivering reliable AI Employees
You Might Be a Fit If You...
- Have 4+ years of experience as a software engineer, automation engineer, or systems builder shipping production systems
- Understand multi-turn conversation design: state management, context windows, interruption handling, and graceful recovery
- Have tackled real-time constraints in production: latency budgets, streaming audio, fallback paths, and API chaos
- Have hands-on experience deploying voice agents using leading platforms (e.g., ElevenLabs, Retell, Nextiva), including telephony and streaming audio integration patterns
- Write automated tests as a matter of course — unit tests, integration tests, and end-to-end workflow validation — and treat testing as part of shipping, not an afterthought
- Apply solid engineering fundamentals: error handling, retry strategies, separation of concerns, and clean interfaces between components
- Are comfortable owning delivery outcomes end-to-end — not just writing code — including timelines, reliability, and client success
- Have deep experience with agentic architectures and APIs, and have shipped real integrations in production
- Understand LLM orchestration, prompt engineering, function calling, and retrieval-augmented generation (RAG)
- Can prototype fast and finish the job to production quality — with tests, error handling, monitoring, and runbooks
- Are an elite debugger who can reason through edge cases, flaky agents, and real-world API failures
- Communicate clearly and fluently in English — both in writing and verbally — especially when articulating technical decisions, tradeoffs, and implementation choices to technical and non-technical stakeholders alike
- Provide your own computer with reliable, high-speed internet. Be willing to work in Americas time zones.
- Can run meetings, drive decisions, write crisp updates, and ask the right questions early — without needing heavy process
- Thrive in fast-paced, ambiguous startup environments and take ownership without being asked
- Bring a low-ego, high-integrity approach to collaboration and leadership
What Success Looks Like
- Voice-first AI Employees are delivered on time, meet customer requirements, and perform reliably in production
- Client implementations are predictable, well-architected, and resilient under real-world conditions
- Complex conversational and voice workflows behave consistently and recover gracefully from failure
- Code is well-tested, well-documented, and maintainable — not just functional
- Technical decisions are communicated clearly and proactively to stakeholders, with tradeoffs explained and risks surfaced early…
