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.

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:

5+ years building Ruby applications with deep Rails expertise
Strong architectural skills—you've designed systems, not just implemented features
Extensive ReactJS experience, 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

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 😎
