Original job description

About Matter Matter is building the first nutrition platform that pairs personalized nutrition intelligence with precisely tailored meals. Think of Matter as a personal nutritionist in your pocket (the app) speaking directly to your private chef (the restaurants). Our app learns each user's goals, preferences, and health data to provide meal recommendations based on their exact nutritional needs. By closing the loop between digital health signals and healthy food preparation, Matter makes precision nutrition as easy as ordering a meal.

The Matter app sits at the center of this experience: nutrition coaching, precision ordering, AI-enabled chat and photo logging, with engagement tools to track progress and inspire action. Wearable device and biomarker integrations support a reinforcement learning cycle to better guide each user and adapt to their evolving needs. Role Overview We're looking for a senior full-stack engineer to help build the Matter consumer app: our AI nutrition coach, tracking and personalization features, and the ordering experience that connects users to our restaurants. You'll ship across the app and the backend services that power it.

This role is for an engineer who is genuinely AI-forward. You use AI tools every day to write, review, test, and ship code faster, and you know how to build AI-powered features that hold up in production. You'll work on a small, high-velocity team and partner closely with product and design. Core Responsibilities Build the Consumer App

Ship features end to end across our React Native consumer app and the services behind it
Build the core app experience, including onboarding, tracking, progress, subscriptions, and in-app ordering
Design APIs, data models, and real-time features that scale with a growing subscriber base
Own app integrations with payments, notifications, and health data platforms

AI & Personalization

Build and improve LLM-powered features, including our AI nutrition coach, conversational and photo logging, and personalized recommendations
Design prompts, evaluations, and guardrails that make AI features accurate, fast, and safe for health-related use
Work with product to decide where AI genuinely improves the experience and where it doesn't

Engineering Velocity & Quality

Use AI coding tools and agents as a core part of your workflow, and help the team adopt practices that increase output without sacrificing quality
Improve CI/CD, testing, monitoring, and observability so we can ship fast with confidence
Write clean, well-structured code and give thoughtful code reviews
Take ownership of production systems, including debugging, incident response, and performance

What We're Looking For

10+ years of professional software engineering experience, including significant full-stack work
Deeply AI-forward: uses AI coding tools and agents daily, with clear examples of how they've made you and your team faster
Experience shipping LLM-powered features to production, with a practical understanding of prompting, evals, latency, and cost
Personally passionate about health, wellness, and fitness, with hands-on experience using macro tracking apps
Strong TypeScript skills across React Native frontends and Node backends
Solid experience with relational databases, data modeling, and backend architecture
Track record of shipping and maintaining high-quality consumer mobile apps
Comfortable owning production infrastructure, deployments, and monitoring
Experience with subscriptions, payments, or in-app commerce is a plus
Experience with health data integrations (Apple Health, wearables, biomarkers) is a plus
Strong product sense and care for the end user experience
Comfortable in ambiguity, with a bias toward shipping over planning

Why Matter

Build a product that helps people eat better, feel better, and reach their health goals every day
Work at the intersection of consumer mobile, AI, and health
Direct impact on product direction on a small, high-velocity team
Tight collaboration with the founding team

Compensation & Benefits

Meaningful equity
Medical, dental, and vision coverage
Flexible PTO plus paid company holidays
Paid parental leave
Free Matter meals

Matter is an equal opportunity employer. We welcome applicants of all backgrounds and do not discriminate on the basis of race, religion, color, national origin, sex, sexual orientation, gender identity, age, disability, veteran status, or any other protected characteristic.
