Freelance Ruby On Rails Web Developer Jobs in Dallas, TX

Job Title: Senior Front End Rails Engineer

Location: U.S. Remote

Who we are:

CYPHER Learning is the AI-native learning platform for organizations that need to train employees, customers, and partners at scale. While many platforms layer AI onto legacy systems, CYPHER was built differently. At the center of our platform is CYPHER Agent, a natural-language, agentic interface that connects content creation, administration, delivery, personalization, and analytics in one unified system. Organizations can create and launch training in minutes, not months, and deliver it seamlessly across distributed audiences. We help companies move faster and turn learning into measurable performance. As we continue to redefine the LMS industry, we are looking for builders who want to help scale the business to new levels.

The Role:

As a Senior Front End Rails Engineer, you will architect and build the core systems that power CYPHER’s products at scale. You will take ownership of complex technical challenges, drive thoughtful design decisions, and set a high bar for code quality, performance, and reliability. In this role, you will mentor and elevate other engineers, influence engineering best practices, and partner closely with cross-functional teams to deliver impactful software. Your work will directly shape a scalable, resilient platform and meaningfully enhance how users experience CYPHER products every day.

What You Will Do:

• Architect, build, and evolve complex, production-grade software systems that underpin CYPHER’s core products, with a focus on scalability, reliability, and long-term maintainability.

• Own technical design and execution for significant features and services, translating product and business requirements into clear, well-reasoned engineering solutions.

• Set and uphold engineering standards through rigorous code reviews, design discussions, and technical documentation that raise the quality bar across the team.

• Mentor and develop engineers by providing hands-on guidance, thoughtful feedback, and technical coaching that accelerates individual growth and team effectiveness.

• Optimize system performance and resilience, identifying bottlenecks, reducing technical debt, and improving observability across the software stack.

• Partner cross-functionally with Product, Design, and other stakeholders to deliver high-impact initiatives on time, balancing speed, quality, and architectural integrity.

• Lead troubleshooting and root-cause analysis for complex production issues, driving durable fixes and preventing recurrence.

• Evaluate and introduce new technologies or approaches where they provide clear value, while continuously improving existing systems and development practices.

• All other duties as assigned.

Your Skills & Experience:

• 8+ years of professional software engineering experience, delivering and operating scalable, high-performance systems in production environments required.

• Strong proficiency in Ruby on Rails, JavaScript, and at least one modern frontend framework (e.g. React, Vue, Angular) with sound judgment in application of these technologies to solve complex problems.

• Deep expertise in object-oriented programming principles and system architecture, including the ability to design maintainable, extensible, and resilient solutions.

• Hands-on experience with cloud platforms (AWS, Azure, GCP) and building or operating distributed systems in fast-moving environments.

• Demonstrated technical leadership through influence, mentoring engineers, facilitating alignment across engineering and product partners, and contributing to sound technical decision-making.

• Advanced understanding of software architecture, design patterns, and engineering best practices, applied pragmatically to balance speed, quality, and long-term health of the platform.

• Proven problem-solving capability under pressure, with the composure to diagnose complex issues, adapt quickly as priorities shift, and drive effective resolution during critical situations.

• Clear, confident communicator, able to collaborate with cross-functional stakeholders and articulate technical concepts in ways that enable alignment and informed decision-making.

• Bachelor’s or Master’s degree in Computer Science, Engineering, or a closely related technical field required.

Our Values:

• Curiosity: Continues learning to stay agile and innovative.

• Connection: Embracing and celebrating our differences.

• Empowerment: Rewarding positive people-centric behaviors and decisions.

• Potential: Challenging the status quo and pushing for what is possible.

• Impact: Making a positive impact for our clients and communities around the world.
