Full Job Description

📋 Description

  • Senior Rust Engineer role at NextLink Labs LLC, a fast-growing technology firm specializing in building, scaling, and securing software applications for clients across industries. This position is critical to delivering secure, high-performance backend systems that enable client success through effective and scalable technology solutions.
  • Design, develop, and maintain scalable backend services using Rust, with direct client engagement to demonstrate progress, gather feedback, and ensure alignment with business goals in a remote-first, agile consulting environment.
  • Collaborate with cross-functional engineers to architect modular, well-structured solutions using workspace crates (model, domain, data, service), applying Clean Architecture, CQRS, event sourcing, and actor-based concurrency patterns to build resilient, observable systems.
  • Implement and optimize gRPC services for inter-service communication, leveraging Tonic and async runtimes like Tokio, while building data access layers for relational (e.g., PostgreSQL), time-series (e.g., TimescaleDB), and graph (e.g., Neo4j) databases.
  • Participate in daily stand-ups, weekly agile ceremonies, code reviews, and observability initiatives using OpenTelemetry and Tracing to ensure system reliability, performance, and security compliance including JWT-based auth.
  • Contribute to technical excellence by mentoring peers, advocating for best practices in testing (unit, integration, BDD/Cucumber), and driving ownership across software engagements from inception to deployment and monitoring.
  • Join a remote-first, inclusive culture that values clarity, autonomy, and outcomes — offering flexibility to thrive professionally while maintaining work-life balance in a growing technical consulting firm.
  • Gain deep expertise in modern distributed systems, cloud-native deployment (Kubernetes, AKS), and observability stacks (Grafana, Azure Monitor), positioning you as a leader in secure, scalable backend engineering with exposure to enterprise-grade architectures.

🎯 Requirements

  • 5+ years of experience building backend services, with at least 2-3 years of production Rust development
  • Strong understanding of Clean Architecture, CQRS, Event Sourcing, and actor-based concurrency patterns
  • Experience designing and implementing gRPC APIs; familiarity with Tonic is a plus
  • Proficiency with relational, time-series, and graph databases — experience with TimescaleDB and Neo4j preferred
  • Strong testing practices including unit and integration testing; familiarity with BDD frameworks like Cucumber is a plus
  • Understanding of security best practices including JWT-based authentication and authorization

🏖️ Benefits

  • Remote-first culture with flexible work schedule and autonomy to do your best work
  • Responsibility and ownership at a growing technology consulting firm
  • Opportunity to build something big and exciting while working with diverse client engineering teams
  • Inclusive, collaborative environment that supports professional growth and personal well-being outside of work
