Full Stack Engineer (Mid-Level)

About the Role:

We’re looking for a Full Stack Engineer to join our fast-moving product and engineering team. You’ll help build and refine the tools that power Realm’s mission to transform the home renovation experience.

You’ll build features that help homeowners price, scope, and visualize their projects; empower contractors to evaluate, bid, and manage them; and streamline operations for Realm’s home advisor team. Along the way, you’ll be at the forefront of AI innovation.

You’ll work across the stack using React on the frontend and Ruby on Rails on the backend, collaborating closely with design and product to bring new ideas to life. This is a great role for someone who’s excited to take more ownership of their work, grow quickly, and make a real impact at a fast-paced startup.

This is a full-time, Los Angeles-based hybrid role (3 days in office).

About Realm:

Realm is on a mission to help homeowners complete their renovations and new builds with confidence, ease, and financial clarity. We guide them through every step of the pre-construction journey—from understanding timelines and permitting to refining scope and securing financing. We then match homeowners with high-quality contractors, help set expectations, and support them even after construction begins.

We’re an early stage startup founded in 2019 building a category-defining platform for home renovation. Our small but mighty team is based primarily in Los Angeles (Culver City).

What You’ll Do:

• Ship full-stack features using Ruby on Rails and React


• Work closely with product, design, and data engineering to bring ideas to life


• Contribute to code quality, reliability, and performance improvements


• Own or collaborate with senior engineers on technical decisions and implementation


• Help integrate AI features and tools into the product


• Participate in code reviews and knowledge-sharing

What You’ll Need:

• 2–4 years of experience building full stack web applications


• Experience working with Ruby on Rails and PostgreSQL


• Proficiency with React for building modern UIs


• Ability to move quickly and take ownership of your work


• Strong communication and collaboration skills


• Comfortable in a fast-paced, iterative startup environment


• Based in Los Angeles

Nice to Have (But Not Required):

• Experience working with AI tools or integrating LLMs into production features


• Familiarity with React Native and interest in contributing to the mobile experience


• Experience integrating with Salesforce (SFDC) or other third-party platforms


• Experience using Tailwind CSS for building clean, responsive UI components

Why Join Us?

• Join a mission-driven company transforming the renovation and home improvement industry


• Competitive compensation, including equity.


• Work with a collaborative, passionate, and high-output team.


• Fast-paced startup environment with tons of growth opportunities.
