Product Engineer (Full stack), Shared Services Platform - Miami, FL

Extenteam Careers; Miami (FL); On-site; USD 120,000 - 180,000; Full time

Job summary

Extenteam is the AI-driven operations platform for short-term rental property management, based in Miami. This in-office role requires working four days per week and sits in the Engineering team reporting to the Head of Engineering.

You will build and ship production-ready features end-to-end—from backend to the AI surfaces of the product—collaborating with operations, product, and design to improve the platform used by 80,000+ properties worldwide.

Qualifications

• 4+ years of full-stack software engineering shipping production enterprise software.
• Direct experience building internal tools, agent-facing platforms, or operational systems.
• Product-minded with ability to scope problems and tradeoffs.
• Track record of shipping fast within a product/design process.
• Experience working asynchronously with distributed teams.

Responsibilities

• Own features end to end including design, backend, frontend, instrumentation, rollout and follow-up fixes.
• Collaborate with founders, product and design at the whiteboard stage to decide what to build.
• Build AI surfaces of the product: prompt and agent architecture, tool calling, retrieval, guardrails and human-in-the-loop safety.
• Build and maintain evals with regression suite.
• Observe real usage: session replays, logs, transcripts, support tickets, and customer calls; ship changes accordingly.
• Own details that make software feel good: latency budgets, token cost, empty states, error copy, loading behavior, keyboard paths.
• Argue a feature is wrong before you build it; cut scope if needed.
• Leverage counts as product work: CI, preview environments, seed data, debugging surfaces.

About Extenteam

Extenteam is the AI-driven operations platform for short-term rental property management, headquartered in Miami and founded in 2021. Our platform, Shared Services, handles guest communication and daily operational workflows for 80,000+ properties by pairing an AI orchestration layer with a shared-services team of hospitality-trained specialists, so no guest inquiry goes unanswered, day or night, and no property manager has to staff for the 2am cancellation themselves.

We're industry-only: every workflow, integration, and agent we hire is built around property management specifically, not bolted on from a generalist platform. As we push more of that platform toward AI-led automation and self-serve tools, the software our own Shared Services team works in every day has to keep pace, that's this role.

Why This Role Exists

Shared Services' guest communication runs on two things: an AI layer that handles as much of a conversation as it safely can, and a shared-services team of hospitality-trained agents who catch what the AI shouldn't touch alone. Every day, that team hits walls in the platform they use to do the work; bugs, missing tooling, workflows that don't match how a busy overnight shift actually runs. Some of that is a quick fix. Some of it is a signal that the platform is failing at scale, and by the time it reaches Engineering it's already cost real client trust.

We don't have a layer of PMs pre-chewing every one of those signals into a spec. We're hiring an engineer who can sit close to Operations, tell the difference between a one-off bug and a systemic gap, and ship the fix with no handoff required.

The Role

You'll report to the Head of Engineering. Priorities are set jointly with the Head of Operations, who owns the operational signal driving what gets built. You'll do two things:

1. Close incoming platform tickets from Shared Services. Agents, Team Leads, and Operations report issues daily; quick fixes, workflow bugs, configuration problems. You triage, diagnose, and ship.


2. Find the pattern and fix it at the source. When multiple agents report the same friction, that's not a ticket, it's a product problem. When a client complaint traces back to repeated agent failures, you ask why the platform is allowing it, and you close that gap for good.

Every ship goes through the same process as any other engineer's here: product filters for coherence, design filters for UX consistency, standard code review. This role works inside those guardrails, not around them.

What You Will Do

• Own features end to end; problem framing, design, backend, frontend, instrumentation, rollout, and the follow-up fixes nobody filed a ticket for.


• Work with founders, product, and design at the whiteboard stage, before anything is written down, and help decide what's worth building.


• Build the AI surfaces of the product; prompt and agent architecture, tool calling, retrieval, guardrails, and the human-in-the-loop escape hatches that make automation safe to ship.


• Build and maintain evals. Treat \"does this actually work\" as an engineering artifact with a regression suite, not a vibe check before launch.


• Watch real usage. Session replays, logs, transcripts, support tickets, and customer calls. Bring back what you learn as shipped changes, not as a document.


• Own the details that make software feel good; latency budgets, token cost, empty states, error copy, loading behavior, keyboard paths. These are part of the feature, not a separate polish phase.


• Cut scope and kill things. Argue a feature is wrong before you build it well.


• Compound the team's velocity; CI, preview environments, internal tools, seed data, debugging surfaces. Leverage counts as product work.

What This Role Is Not

• Not a ticket queue firefighter. That's other roles on the Operations side.


• Not a shadow engineering team. You report to and work within Engineering.


• Not an independent operator building outside the platform. Everything you ship goes through product.

Anti-Signals

• You want a ticket fully spec'd before you'll touch it


• You treat \"why does this keep happening\" as someone else's question to answer


• You measure your work by whether you closed the ticket, not whether the pattern stopped


• Your AI/LLM experience is prompting a demo — never held to a reliability bar with a real agent depending on it at 2am

Required Experience

• 4+ years of full stack (stronger on the BE) software engineering experience shipping production enterprise software


• Direct experience building internal tools, agent-facing platforms, or operational systems


• Product mindset: comfortable scoping problems, asking the right questions, and communicating/prioritizing tradeoffs


• Track record of shipping fast while working inside a product and design process


• Experience working asynchronously with distributed teams

Required Technical Skills

• Strong fluency in TypeScript. We currently use:
  
  
  • Next JS
  
  
  • NestJS
  
  
  • TypeORM with Postgres
  
  
  • BullMQ
  
  


• Comfortable with agentic coding tools (Claude Code, Cursor, Replit Agent)


• API integration experience (REST, webhooks, third-party SaaS APIs)


• Prompt engineering experience with production AI systems (OpenAI, Anthropic, or similar)

Strongly Preferred

• Experience building tools for contact center, customer support, or operations teams


• Short-term rental, hospitality, or property management domain knowledge


• Track record of deploying AI agents in production

How You'll Work

• Reports to the Head of Engineering


• Priorities set jointly with the Head of Operations, based on operational signal


• Product decisions filter through the Head of Product


• Design decisions go through our design team


• Weekly syncs with Engineering, Operations, and Product


• Miami-based, in-office 4 days per week
