Senior Backend Software Engineer

Key Responsibilities

• Design, develop, test, and maintain backend services, APIs, data models, and integration layers.
• Build reliable backend capabilities for web application workflows, including request handling, validation, persistence, error handling, and service orchestration.
• Collaborate with frontend engineers to define clear and maintainable frontend/backend contracts.
• Work with product, QA, infrastructure, and architecture partners to translate requirements into backend solutions.
• Evaluate technical alternatives, make pragmatic design decisions, and document important trade-offs.
• Troubleshoot complex issues across application, data, integration, runtime, and environment boundaries.
• Write unit tests, integration tests, and validation utilities to improve backend quality.
• Conduct code reviews focused on API design, modularity, testability, maintainability, and operational risk.
• Support CI/CD, deployment readiness, logging, monitoring, and production support practices where applicable.
• Mentor junior engineers through code reviews, design discussions, documentation, and technical sharing.

Required Qualifications

• Bachelor’s degree or above in Computer Science, Software Engineering, Electrical Engineering, Automation, Applied Mathematics, or a related field.
• 7+ years of relevant software engineering experience.
• Strong hands-on backend development experience using Python or similar programming languages.
• Experience designing and implementing RESTful APIs or backend services for production applications.
• Solid understanding of object-oriented programming, modular design, clean code, and maintainable architecture.
• Experience with Docker, Kubernetes, Linux, cloud platforms, observability, logging, monitoring, or scalable system design.
• Experience with relational or NoSQL databases and reliable data access patterns.
• Experience with unit testing, integration testing, debugging, Git-based workflows, code review, and CI/CD.
• Ability to analyze requirements, clarify ambiguity, evaluate trade-offs, and deliver solutions independently.
• Strong communication and collaboration skills across engineering, product, QA, and infrastructure teams.

Preferred Qualifications

• Experience with backend frameworks such as FastAPI, Flask, Django, or similar technologies.
• Experience building backend services for complex web applications, enterprise applications, engineering software, or data-driven platforms.
• Experience with API contract design, schema validation, versioning, and backward-compatible API evolution.
• Experience with asynchronous processing, long-running tasks, workflow orchestration, or distributed systems.
• Experience with performance profiling, troubleshooting, query optimization, or backend reliability improvements.
• Experience mentoring engineers or leading backend design discussions.

Success Profile

A strong candidate is more than a backend implementer. They can take ownership of backend features from design through delivery, keep APIs understandable as requirements evolve, and improve the reliability, testability, and maintainability of the backend codebase.

They balance delivery with long-term engineering quality, know when to introduce abstraction and when to keep things simple, and help the team make better technical decisions through hands-on contribution.
