Full Stack Engineer (Ruby / JS), Remote Job
We are looking for a mature Software Engineer with a product mindset to join our team! The position will include building great products, tackling interesting challenges, and contributing to our engineering culture. We expect you to work in pairs, use test-driven development, be experienced in building complex web and mobile applications, and write both clean and maintainable code.
What "mature" means to us:
• You've navigated ambiguous problems and designed systems that scaled
• You make pragmatic technical decisions that balance quality with business impact
• You help your team grow through pair work, thoughtful code reviews, and knowledge sharing
• You communicate technical complexity clearly to both engineers and stakeholders
What you will work on
You'll work on both Railsware products and solutions designed for our clients. Here's the scale and complexity you'll tackle:
• Mailtrap.io - An email delivery platform serving 1M+ users globally. Challenges include high-volume email processing, real-time delivery tracking, and API design for diverse integration needs.
• Coupler.io - a data integration and AI analytics platform handling millions of records daily. Think resilient data pipelines, complex transformations, AI integration, and data consistency across systems.
• TitanApps.io - a set of productivity tools for Jira. We architect integrations with third-party APIs, optimize performance for large datasets, and design intuitive UIs for complex workflows.
• NexHealth - Patient experience platform transforming healthcare. Tasks include HIPAA-compliant architectures, real-time scheduling systems, and integrations with healthcare providers.
• Tradezella - №1 trading journal with sophisticated analytics. Build data visualization systems, complex calculation engines, and real-time market data processing.
• Knowa - Executive-level project management solution. Design intuitive interfaces for high-level insights and build aggregation systems for complex organizational data.

Our tech philosophy: We primarily use Ruby and ReactJS, but our codebases are polyglot by design. We actively experiment with Golang, Python and Node.js in production when they're the right tool. You'll have a voice in technical decisions and technology choices.
What We're Looking For
Technical Foundation:
• 4+ years building Ruby applications with deep Rails expertise
• Strong architectural skills—you've designed systems, not just implemented features
• Willingness to work with frontend technologies, particularly JS and React, including state management and performance optimization
• Hands-on experience with multiple database systems
• Production experience with cloud platforms (AWS, GCP, Digital Ocean, Heroku)
• Comfortable with UNIX/Linux environments
• TDD practitioner–you write tests that give confidence, not just coverage
Will be a plus:
• Hands-on experience with AI-assisted coding tools (e.g. GitHub Copilot, Antigravity, Cursor, Windsurf, ChatGPT-based tools)
Professional Maturity:
• Proven ownership. You've led complex features from architecture through production, including stakeholder management
• Technical communication. You can explain trade-offs, advocate for technical investments, and write clear documentation
• Collaborative problem-solver. You build consensus, mentor others, and improve team practices
• Product thinking. You understand user needs and business constraints, not just technical requirements
• Good English for written and verbal communication across distributed teams
What Sets Exceptional Candidates Apart
• Experience with pair programming and ensemble programming practices
• Track record of reducing technical debt while maintaining feature velocity
• Open-source contributions or technical writing that demonstrates expertise
• Experience with distributed systems, event-driven architectures, or microservices
• Background in domains like fintech, healthcare, or SaaS platforms at scale
What You Will Do
• Own end-to-end feature delivery, from technical design and architecture through implementation, testing, and production support
• Drive technical decisions for your domain, including technology choices, architectural patterns, and quality standards
• Elevate code quality through comprehensive testing, thoughtful refactoring, and maintainable design patterns
• Mentor and collaborate: conduct thorough code reviews, pair with team members, and share knowledge actively
• Shape product direction: identify technical opportunities and constraints that influence product decisions
• Proactively improve: spot and address technical debt, performance bottlenecks, and architectural concerns before they become problems
• Communicate clearly: keep stakeholders informed of progress, risks, and technical trade-offs
• Enjoy engineering again
