Senior Full Stack Software Engineer

Senior Full Stack Software Engineer (Ruby on Rails + Modern Frontend)

Company: HEXA Containment

Location: Houston, Texas (Remote)

Job Type: Full-Time

About HEXA Containment:

HEXA Containment is a leading, tech-forward supplier to the rental industry. We are dedicated to building scalable, maintainable, and high-impact software solutions that drive real value for our customers.

We value ownership, collaboration, and pragmatic problem-solving. Our team thrives on working through ambiguity and tackling challenging problems that push us to grow as engineers and product thinkers. Not all features or functionality are known upfront, so we focus on understanding our users' core problems, experimenting with solutions, and delivering value quickly—while maintaining high-quality engineering standards. We move fast, but we think deeply about what we build and why.

Job Summary:

We’re looking for a Senior Full Stack Engineer with strong backend experience in Ruby on Rails and solid working knowledge of modern frontend technologies. You’ll play a key role in shaping our architecture, product direction, and user experience—working closely with founders, product managers, and designers to define problems, iterate on solutions, and ship impactful features.

This role isn’t just about writing code—it’s about thinking critically, asking the right questions, and helping the team make smart trade-offs that maximize product impact. You’ll spend more time in backend systems but should feel comfortable contributing meaningfully to frontend implementation, collaborating with designers and frontend engineers to deliver complete, high-quality experiences.

If you enjoy working end-to-end—turning early ideas into well-crafted features—and thrive in a collaborative, product-driven environment, this role is for you.

Key Responsibilities & Functions:

• Shape and refine early-stage or high-level requirements by clarifying objectives, identifying core problems, and communicating assumptions.
• Make informed tradeoffs and clearly articulate the implications of different technical approaches.
• Propose, estimate, and plan solutions that align with business goals.
• Own features end-to-end—from backend architecture to user-facing implementation—with a focus on maintainability, usability, and performance.

What You'll Do:

• Design, develop, and maintain scalable backend services using Ruby on Rails.
• Build and enhance user-facing functionality using modern frontend technologies (React, Hotwire, or similar frameworks).
• Collaborate cross-functionally with product, design, and engineering peers to translate business challenges into elegant, working solutions.
• Evaluate trade-offs in architecture, performance, and maintainability to make pragmatic technical decisions.
• Improve code quality, testing practices, and deployment processes across the stack.
• Participate in code reviews, mentorship, and technical discussions that raise the overall quality of the team.
• Advocate for best practices in software engineering, architecture, and product design.

What YOU Bring:

• 5+ years of professional software development experience, with strong proficiency in Ruby on Rails.
• Experience with modern frontend development, such as React, Vue, or Hotwire—comfortable writing and maintaining UI components, but not necessarily a deep frontend specialist.
• A product-minded engineer who thinks beyond the code—you care about solving real problems and delivering value.
• Experienced in agile, iterative development, with an eye for shipping fast and improving continuously.
• Comfortable working with databases (PostgreSQL) and designing clean, reliable APIs (REST, GraphQL, etc.).
• Strong communicator who asks clarifying questions, identifies trade-offs, and drives clarity across product and technical discussions.
• Proactive, collaborative, and comfortable taking ownership of outcomes.

Preferred:

• Experience with ecommerce or marketplace platforms.
• Exposure to scaling high-traffic or distributed systems.
• Familiarity with cloud infrastructure (AWS, Azure, etc.).
