π― Who is this job for?
This position is best suited for a Senior Software Engineer with 5+ years of experience, strong in Ruby and comfortable with IAM systems, microservices, and scalable architectures. Candidates should understand CI/CD, REST/gRPC, and be open to working with Go, Scala, or TypeScript/React. Ideal for engineers who enjoy cross-functional collaboration, mentoring, and owning secure, performant services in a remote Agile environment.
π¬ Potential Interview Questions
-
What are the key benefits of using Ruby for building scalable backend services?
Ruby offers concise, readable syntax and strong community support; combined with frameworks like Rails, it accelerates development while enabling maintainable, modular service design. -
How do you implement authentication and authorization in a microservices architecture?
By using token-based authentication (e.g., JWT), centralized identity providers (e.g., OAuth2/OpenID), and service-level authorization checks, often enforced via middleware. -
What’s the difference between REST and gRPC, and when would you use each?
REST uses JSON over HTTP and is human-readable, ideal for public APIs; gRPC is binary, uses Protocol Buffers, and is faster and better suited for internal microservice communication. -
Describe your experience with Identity and Access Management (IAM) systems.
I’ve worked on designing user roles, scopes, and permission models, integrating OAuth2 providers, and building secure login flows and token handling for user/resource access. -
How do you ensure high availability and fault tolerance in a microservices architecture?
I use techniques like redundancy, graceful degradation, retries with exponential backoff, health checks, circuit breakers, and horizontal scaling on orchestration platforms. -
How do you structure and test a secure Ruby service for IAM functionality?
Use layered architecture with clear separation of concerns, write unit and integration tests with RSpec, and perform security-focused testing like input validation and token misuse. -
What are best practices for integrating security into the SDLC?
Include threat modeling in design, enforce code reviews for security flaws, use static/dynamic analysis tools, and integrate dependency checks into CI pipelines. -
How would you optimize database queries in a high-performance web service?
Use indexing, avoid N+1 queries, cache expensive reads, analyze query plans, and batch data operations when possible. -
Describe your experience mentoring or leading junior developers.
I provide structured code reviews, pair programming, share resources, set goals, and offer consistent feedback to support growth and autonomy. -
What steps would you take when designing a new IAM feature for a multi-tenant system?
Identify tenant boundaries, design flexible role/permission hierarchies, ensure secure data isolation, and account for scalable authentication flows with logging and audit trails.
