Description
12-month contract to hire/1099
Location: Northwest Arkansas (On-site/Hybrid)
FIELDBOOK, a studio operated by Alloy Partners, is dedicated to creating and accelerating advantaged retail technology startups. We are seeking a Senior Full Stack Developer to help build and scale Umami.
Umami is an AI-enabled Food & Beverage innovation platform that analyzes customer reviews and consumer data to generate strategic product insights for CPG brands. We turn millions of customer reviews into actionable business intelligence — combining machine learning, consumer data, and a brand's unique advantages to take innovators from insight to innovation.
As the Senior Full Stack Developer, you will work closely with the Co-Founder/CEO and Head of Product as a core technical thought partner and the primary builder of the platform. You'll work across a sophisticated stack involving LLM APIs, complex data pipelines, automated data acquisition, and modern frontend frameworks.
Who You Are:
- You take ownership — you treat the product like it's yours and don't wait to be told what needs attention
- You're solution-oriented — you identify problems but show up with answers, not just concerns
- You're accountable — you do what you say you're going to do, within the time you committed to
- You know when to escalate and when to just solve it — you can distinguish between decisions that need leadership input and problems that have commonly acceptable solutions
- You're pragmatic — you value code quality but avoid over-engineering, and you ship things that work
- You thrive in small, high-trust teams where autonomy is high and process is lean
- You find the work genuinely enjoyable — we're supporting food innovation, not curing cancer. Let's have fun together.
What You'll Do:
- Build and optimize AI analysis pipelines (review → product → brand → persona aggregation)
- Develop source-specific data acquisition and content extraction logic
- Design and implement Vue/Inertia frontend features with complex data visualization
- Write and maintain comprehensive test coverage (Pest v4)
- Optimize database queries and job queue performance
- Integrate with OpenAI API for structured analysis
- Debug distributed queue systems and async processing issues
- Collaborate on API design and data schema evolution
- Participate in code reviews and architectural decisions
What You'll Work With:
- Backend: PHP 8.3 / Laravel 12
- Frontend: Vue 3 (Composition API) / Inertia.js v2 / TypeScript
- Styling: Tailwind CSS v4
- AI/LLM: OpenAI GPT-4 with structured outputs
- Database: MySQL 8.0
- Testing: Pest v4
- Real-time: Laravel Reverb (WebSockets)
Requirements
- 6+ years in PHP/Laravel — modern architecture, queue systems, complex Eloquent relationships
- 6+ years in JavaScript/TypeScript — component-based architecture, reactive state management
- Real production experience with LLM/AI APIs — structured outputs, prompt engineering, token management, rate limiting, and failure handling
- Experience building and debugging distributed queue and async job systems
- Strong testing discipline — TDD mindset, mocking external services, E2E experience
- Ability to communicate technical risk and trade-offs clearly to non-technical founders
- Comfort reading, improving, and owning unfamiliar codebases
Nice to Have:
- Vue 3 Composition API and/or Inertia.js experience
- Familiarity with MCP servers and agentic AI development workflows
- B2B SaaS or CPG/retail domain experience
- Data visualization (Chart.js, D3.js)
Benefits
- Competitive compensation. This will be a 1099 position until Umami is spun out and incorporated
- A collaborative, flexible, and entrepreneurial environment with a proven venture studio playbook
- A highly validated concept and business model hypothesis developed by our team
- The support of the venture studio and platform services, our goal is to surround the startup with world-class expertise in every discipline required to build a market-leading company
