Descripción de la vacante

Peek Travel Inc. is seeking a Senior Full Stack Engineer who works AI-first, focusing on agent orchestration and end-to-end feature delivery.

You will design, build, and operate systems spanning ACME operations tools, scheduling widgets, and enterprise-grade solutions for operators in the experiences industry. The role emphasizes shipping real product features with AI-assisted development, maintaining high code quality, and collaborating with Product and Design to close gaps in specifications.

Formación

• 5+ years of professional development using Java and/or JavaScript with a track record of shipping production systems.
• Strong backend fundamentals including API design, data modeling, SQL, and service reliability.
• Demonstrated daily use of AI coding tools (Claude Code, Codex, Cursor) in production workflows.
• Ability to critically evaluate AI-generated code for correctness, security, and maintainability.
• Strong system design instincts and the ability to reason about scale and failure modes.
• Clear communicator who can articulate technical decisions and challenge specs constructively.
• Interest in Elixir or functional programming as stack evolves.

Responsabilidades

• Architect and break down ambiguous product problems into concrete, well-scoped tasks for agents to execute and ship features.
• Design and operate complex agent orchestration systems that ship real product features.
• Design APIs and data models that are clean, maintainable, and scalable.
• Contribute to an AI-first engineering culture, sharing patterns and documentation.
• Review AI-generated outputs and ensure code quality before production.

As a remote-first company recognized by Forbes as one of America's Best Startup Employers and by Built In as a 2025 and 2026 Best Place to Work, we are a global team of "Peeksters" who "Obsess Over Our Customers," "Accomplish Big Things," "Collaborate With Purpose," and "Get Better Every Day."

The Role

We work on several systems: our ACME operations management suite, embeddable scheduling and booking widgets, B2B and B2C sales and support tooling, and custom solutions for enterprise operators. The work is technically varied, and the stakes are real: operators depend on this software to run their businesses.

We’re hiring a Senior Full Stack Engineer who works AI‑first. That means you treat AI as a core part of how you build, break down ambiguous problems, delegate to agents, review their work critically, and course‑correct when things go sideways. You'll design and operate complex agent orchestration systems, develop patterns for human‑agent collaboration, and ship real product features primarily through agent‑assisted development.

Over the past few months, we’ve seen a step‑function improvement in the reliability and capabilities of long‑running AI agents. We’re adapting our engineering practice to match, and we want engineers who are already building this way and are excited to push it further.

What you’ll do

• Architect and break down ambiguous product problems into concrete, well‑scoped tasks for agents to execute and ship full‑stack features, owning work from design through production release.

• Design and operate complex agent orchestration systems that ship real product features.

• Design APIs and data models that are clean, consistent, and built to last, not just fast to write.

• Contribute to our AI‑first engineering culture, share patterns, document what works, and help the team level up on how we build with AI.

• Use AI tools fluently - Claude Code, Augment, or equivalent- to compress implementation time, then critically review everything that comes out of them.

• Collaborate closely with Product and Design to identify gaps in specs, surface edge cases early, and push back when something isn’t ready to ship.

• Set the quality bar: well‑structured, maintainable code; conduct thorough code reviews; maintain adequate test coverage; and catch bugs introduced by AI before they reach production.

What We're Looking For

Required

• 5+ years of professional development using Java and/or JavaScript with a meaningful track record of shipping production systems.

• Strong backend fundamentals: API design, data modeling, SQL, service reliability, and debugging production issues.

• Demonstrated daily use of AI coding tools (Claude Code, Codex, Cursor or equivalent) in a production engineering workflow.

• Ability to critically evaluate AI‑generated code: catch logic errors, identify security issues, assess maintainability, and own what gets merged regardless of how it was written.

• Strong system design instincts: you think about tradeoffs, edge cases, and what happens when things scale or fail.

• Clear communicator: you can articulate why you made a technical choice, flag when a spec has holes, and disagree constructively.

• Interest in Elixir or functional programming languages as we expand our stack

Nice to haves

• Experience building B2B SaaS products, ideally with complex multi‑tenant data models or transactional workflows.

• Experience on small, high‑output teams where you’ve had to make architectural calls without a committee.

• Frontend experience, particularly with Angular or modern JS frameworks, enough to own a feature end‑to‑end.

• Background in the travel, hospitality, or experiences industry.

What We Value

A few things that define how we build:

• Judgment over speed. AI compresses implementation time. What differentiates engineers now isn’t typing speed or memorized syntax; it’s the ability to make the right calls on what to build, how to build it, and when it’s not ready to ship.

• Ownership. You built it? You own it. That includes AI‑generated code. You know when to use agents and when to do it yourself.

• Directness. We want people who ask hard questions, surface problems early, and are willing to push back on a bad spec rather than build it and hope for the best.

• Quality as a habit. Peer code reviews, test coverage, and clean APIs are not optional. We move fast, but not by cutting corners on the things that compound.
