Mission

As a Senior Backend Engineer, you will be a cornerstone of our engineering team, tasked with designing, building, and scaling the core services that power our platform. You will go beyond writing code; you will own critical systems, make high-impact architectural decisions, and mentor other engineers. If you are passionate about building robust, efficient, and cloud-native systems with Golang, this is your opportunity to leave a significant mark.

Key Responsibilities

• Architect & Build Core Services: Design, develop, and own high-availability, low-latency backend services in Golang that are the backbone of our product.
• Master Data Persistence: Architect and optimize complex data models and interactions using GORM with PostgreSQL, ensuring performance, integrity, and scalability from the ground up.
• Champion Cloud-Native Development: Build, containerize, and orchestrate services using Docker and Dockerfile best practices within a Kubernetes-driven, cloud-native ecosystem.
• Drive System Design & Evolution: Lead the technical design and implementation of new features and systems, making key decisions on patterns, protocols, and technologies.
• Ensure Excellence & Reliability: Establish and uphold standards for code quality, testing (unit, integration, e2e), and observability (logging, metrics, tracing) across the backend stack.
• Mentor & Elevate the Team: Act as a force multiplier by providing technical guidance, conducting code reviews, and mentoring mid-level and junior engineers.

• 5+ years of professional backend development experience, with a significant focus on Golang in production environments.
• Expert-level proficiency with Golang's concurrency model, profiling, and best practices. You don't just use the language; you understand its idioms and internals.
• Deep, practical experience with the GORM framework for complex data access layer design and optimization.
• A strong understanding of PostgreSQL, including performance tuning, query optimization, indexing strategies, and transaction management.
• Proven experience designing and building cloud-native applications. You have a solid grasp of containerization (Docker), and ideally, experience with orchestration (Kubernetes) and cloud providers (AWS, GCP, Azure).
• A passion for building clean, maintainable, and well-tested code. You consider testing and documentation to be part of the development process, not an afterthought.
• Excellent communication skills and a collaborative mindset. You can articulate complex technical concepts to both technical and non-technical stakeholders.
• Experience with gRPC and protocol buffers for building efficient service-to-service communication.
• Knowledge of system design patterns for distributed systems (e.g., saga pattern, CQRS, event sourcing).
