Full-Stack Engineer

What we are looking for

Our customer is in the middle of a deliberate shift from manual, spreadsheet-based operations to purpose-built web tools, and this contract sits right at the center of that work. They have already clearly defined the problems, designed the logic, and in several cases, already have working prototypes ready. What they need is an experienced Full-Stack Engineer to take those designs and prototypes to production-grade web applications.

The work spans several interconnected systems: real-time train tracking and delay management, crew scheduling analytics, automated guest seating allocation, and shift equity monitoring. Where appropriate, these tools will be enhanced with LLM-powered features (using API calls to models like Claude or DeepSeek) to automate narrative outputs, handle exceptions, and surface plain-English insights from structured data.

This is a hands-on individual contributor role. You will work directly with operations leadership, not through layers of project management. The person in this role needs to move fast, communicate clearly about trade-offs, and build things that real operations teams can rely on under pressure.

Start date: June 2026
️Contract type: Full-time, Contractor, 4 months with possibility of renewal/extension
Work hours: Monday to Friday, 8 AM to 5 PM PST
Work mode: 100% remote from LATAM

What You’ll Be Doing

• Reverse-engineer data rules and functional prototypes currently trapped in manual spreadsheets or legacy VBA macros, transforming them into reliable web applications.
• Take features from database schema design (PostgreSQL) and backend API development up to crafting modular, responsive UIs (React/Next.js & Tailwind).
• Integrate LLM APIs into production workflows to automate operational narratives and extract structured insights.
• Build secure integrations against third-party workforce management APIs and implement frontend data-streaming patterns (WebSockets, SSE, or polling) for live operational updates.
• Stand up, configure, and manage your own application deployments on cloud platforms (Azure preferred) independently

What You Need to Succeed

Must-haves

• +6 years of professional experience in Full-Stack Web Development.
• Backend: Strong expertise in Python, C#, and/or Node.js.
• Frontend: JavaScript/TypeScript and Next.js/React.
• Databases: Solid experience with relational databases (PostgreSQL preferred), designing schemas, writing queries, and managing migrations.
• Integrations: Proven experience handling REST APIs (auth, pagination, rate limits) and LLM APIs (prompt engineering, structured outputs, context management).
• Cloud Basics: Ability to deploy and host applications on cloud platforms (Azure preferred) without a dedicated DevOps resource. 

Nice-to-haves & Bonus Points

• Experience migrating Excel/VBA logic to web applications.
• Familiarity with scheduling or workforce management system APIs (Connecteam, Workforce.com, Deputy, etc.).
• Background building operations-facing tooling or working in rail, transit, hospitality, or tour operations environments.
• Experience with real-time or near-real-time data display (websockets, SSE, or polling).
• Familiarity with Microsoft Graph API / Microsoft 365 integrations or data visualization libraries.
• Comfort working from a functional spec rather than a fully detailed technical design

What to Expect from Our Hiring Process

We value your time and believe in a transparent, efficient selection process. Here is what our journey together will look like:

1. HR Screening (60 mins): an initial conversation with our Talent Acquisition team to walk through your background, discuss the role’s context, and align on logistics (availability, contract model, and expectations).
2. Team Engagement Interview (30 mins): a brief session with our Engagement Manager focused on cultural alignment, professional presentation, and communication skills. We want to ensure a mutual fit for our collaborative, flat-structured environment.
3. Final Round: Technical Deep Dive (Up to 2 rounds, 60 mins each). A deep dive into your engineering experience. We will discuss system architecture, database design, and your hands-on experience with full-stack frameworks and LLM integrations. No trick questions, just an engineering-to-engineering discussion about real-world problem-solving.
