Senior Backend Engineer

About the role

Job Description Senior Backend Nest.js Engineer Summary We’re looking for a Senior Backend Engineer to build and evolve reliable, secure, and scalable services that power customer-facing products and internal platforms. In this role, you’ll take ownership of critical backend systems end-to-end—design, implementation, testing, deployment, and ongoing improvement—while partnering closely with Product, Data, and Frontend teams. What you’ll do • Design, build, and maintain backend services and APIs with a strong focus on reliability, performance, and security. • Translate product and business requirements into well-structured technical designs and incremental delivery plans. • Own key architectural decisions, including service boundaries, data models, and integration patterns. • Improve system observability by implementing logging, metrics, tracing, and actionable alerting. • Identify and resolve performance bottlenecks through profiling, optimization, caching, and query tuning. • Write high-quality, well-tested code (unit, integration, and end-to-end tests where appropriate). • Lead code reviews and provide constructive feedback that raises the quality bar across the team. • Collaborate with DevOps/SRE partners to improve CI/CD, deployment safety, and operational readiness. • Mentor engineers by sharing best practices in system design, debugging, and maintainable coding patterns. • Participate in incident response and post-incident reviews, driving preventive improvements and runbooks. Must-have qualifications • Significant professional experience building backend systems in production environments. • Strong proficiency in at least one backend language (e.g., Java, Kotlin, Go, Python, or similar). • Experience designing and operating RESTful APIs and/or gRPC services. • Solid understanding of relational databases and data modeling; ability to write efficient queries and design indexes. • Familiarity with distributed systems fundamentals (consistency, idempotency, retries, timeouts, and failure modes). • Practical experience with cloud platforms and containerized deployments (e.g., AWS/GCP/Azure, Docker, Kubernetes). • Proven ability to communicate clearly, collaborate across functions, and take ownership of outcomes. Nice-to-have qualifications • Experience with event-driven architectures (Kafka, Pub/Sub, RabbitMQ) and asynchronous workflows. • Exposure to domain-driven design, hexagonal architecture, or similar maintainable design approaches. • Experience with infrastructure as code (Terraform, CloudFormation) and modern CI/CD pipelines. • Security knowledge (authn/authz, OAuth2/OIDC, secrets management, threat modeling). • Experience operating high-throughput systems, multi-tenant platforms, or services with strict SLAs. What we offer • Competitive compensation and meaningful ownership in your work • Flexible working arrangements (remote/hybrid options where available) • Time for learning and professional development • Supportive, inclusive team culture focused on craftsmanship and collaboration Our commitment to inclusion We welcome applicants from all backgrounds and experiences. If you don’t meet every requirement but believe you can succeed in this role, we encourage you to apply.
