Is Ruby on Rails a good career?
What Is Ruby On Rails?
Ruby on Rails is an application framework for web development. Specifically, it focuses on server-side functions and relies on the model-view-controller pattern. Rails is the framework itself, while Ruby is the programming language in which Rails is written. Ruby on Rails was designed to cut down on repetitive tasks and to be easy to learn with large, easily accessible libraries. It is open source as well, which means there is a large community that you can utilize to answer questions or improve your skills.

What is the difference between Ruby On Rails vs JavaScript Developer?
| Aspect | Ruby On Rails | JavaScript Developer |
|---|---|---|
| Required Credentials | Proficiency in Ruby, Rails framework, MVC architecture | Proficiency in JavaScript, frameworks like React or Angular, HTML/CSS |
| Work Environment | Backend web development, server-side scripting | Frontend development, client-side scripting |
| Employer & Industry Usage | Web startups, SaaS companies, e-commerce platforms | Web applications, interactive websites, mobile app development |
Ruby On Rails and JavaScript Developers often work together but focus on different parts of web development. Rails is primarily used for backend development with a focus on server-side logic, while JavaScript developers handle the frontend, creating interactive user interfaces. Both roles are essential in full-stack development, but their skills and tools differ significantly.

Principal Software Engineer -CoCounsel
CoCounselis our most advanced AI offering to date - combining generative and agentic AI capabilities to help legal professionals move beyond prompting and start delegating. As a Principal Software Engineer, you will set the technical direction for the backend, AI orchestration, and identity systems that turn frontier models into reliable, secure, production-grade workflows that attorneys, in-house legal departments, and government agencies trust on real client matters every day.
This role sits at the heart of theCoCounselLegal engineering organization, partnering closely with AI/ML engineers, researchers, product, and our identity and platform teams to deliver world-class legal content and AI experiences at scale.
About the role:
In this opportunity as a Principal Software Engineer, you will:
Participate in shapingthe company's AI platform and patterns:Define patterns for building MCP servers, designing agents, novel uses of LLMs, experimentation, and scalable infrastructure. Your decisions will influence multiple product lines, not just a single feature.
Work at real production scale: Build and evolve systems that operate over millions of documents, complex and ever-changing law, privileged client data, and thousands of concurrent AI interactions from professionals doing time-sensitive work. Considering implications tocloud costs, optimizations, etc.
Small team, big surface area:Join a tight group of senior engineers and researchers shipping quickly, with direct access to product leadership and customers. Think ownership of a startup with the runway of a public company.
Technical leadership and cross-functional influence:Leadand/or designinitiatives that cut across AI, product, identity, and infrastructure.Mentor staff and senior engineers, raising the bar onAI integration practices,system design, code quality,andsecurity across the org.Be the expert in new model capabilities, collaborating closely with AI/ML engineers, researchers, designers, and PMs to translate industry improvements into reliable, user-facing workflows that legal professionals trust.Help shape the team's roadmap, technical strategy, and engineering culture - from experimentation practices to testing, rollout, and postmortems.Help define and lead the platform integration strategy across new and existing Thomson Reuters legal systems to deliver world-class content and solutions for our customers.
Identity, access, and trust:Define how autonomous agents act on a user's behalf safely: scoped delegation, least-privilege service identities, secrets management, and consistent enforcement of entitlements across documents, matters, and content repositories.Partner with security, platform, and compliance teams on multi-tenancy isolation, data residency, privilege protection, and the audit trails that legal and government customers require.Consider the design and evolution of authentication and authorization acrossCoCounselLegal - SSO/federation (SAML, OIDC, OAuth 2.0), token and session management, and fine-grained, role- and attribute-based access control (RBAC/ABAC).
Scale, reliability, and performance:Design for high-throughput, low-latency AI workloads: caching, queuing, rate-limiting, model failover, and cost/performance trade-offs.Work with large-scale data: millions of documents, retrieval and search, vector stores, and indexing strategies tailored to legal use cases.Establish and refine SLOs, observability, and incident response for AI systems that must be correct, auditable, and trustworthy in professional legal workflows.
About You:
You are a fit for the position of Principal Software Engineer if your background includes:
Bachelor's Degree in Computer Science, Computer Engineering, a related field, or equivalent experience.
Demonstrated experience building with AI - LLMs, agents, and retrieval - and a strong point of view on what "AI-native" software should look like.
Proven track record owning large, complex projects end-to-end: architecture, execution, rollout, and long-term operation.
Deep Python expertise and experience with production systems using frameworks likeFastAPI(or similar), relational databases (PostgreSQL or equivalent), and a major cloud provider (AWS preferred).
Strong background in distributed systems: data modeling, API contracts, observability, resilience patterns, and performance tuning under load.
Hands-on experience with identity and access management - designing or integrating authentication and authorization at scale (SSO, SAML, OIDC, OAuth 2.0, RBAC/ABAC, token/session management, or comparable IAM systems).
Excellent communication skills and the ability to partner with product, design, security, and ML teams in a fast-moving environment.
Preferred Skills & Experience:
Hands-on experience designing and operating agentic systems in production - tool calling, MCP servers, multi-step workflows, and orchestration around third-party and in-house LLMs (e.g., Anthropic, OpenAI), including prompt/response management, cost controls, and safety considerations.
Experience with AI-adjacent infrastructure: vector databases, embeddings, semantic search, or custom retrieval pipelines.
Opinions and experience around automated testing, reliability, and release practices for systems with non-deterministic model behavior.
