Core Responsibilities

Primary Functions

Design, implement, and maintain modular, testable, and efficient code for new features and system enhancements using established programming languages and frameworks (e.g., Java, Python, C#, JavaScript/TypeScript, .NET, Node.js, React).
Collaborate with product managers, designers, QA, and other engineers to gather requirements, estimate tasks, and deliver well-scoped software increments on time.
Build and consume RESTful APIs and integrate third-party services; produce clear API contracts, documentation, and versioning strategies.
Develop and maintain relational and NoSQL database schemas, write optimized SQL queries, and implement data access layers to ensure application reliability and performance.
Implement unit, integration, and end-to-end tests; adopt test-driven or behavior-driven development practices to reduce defects and increase delivery confidence.
Troubleshoot, debug, and resolve production incidents and performance bottlenecks; perform root cause analysis and propose robust fixes and preventive measures.
Participate in code reviews, provide constructive feedback, and uphold coding standards, style guides, and best practices to improve team quality and consistency.
Design and implement CI/CD pipelines, automated builds, and deployment scripts to streamline releases and reduce manual steps.
Write clear, concise technical documentation, including system design documents, runbooks, API docs, and in-line code comments for maintainability.
Follow secure coding practices, identify and remediate security vulnerabilities, and collaborate with security teams on threat mitigation and compliance requirements.
Implement responsive and accessible front-end features when applicable; optimize client-side performance and cross-browser compatibility.
Maintain version control hygiene using Git: feature branching, pull requests, merges, and conflict resolution; enforce meaningful commit messages and tagging.
Participate in Agile ceremonies (stand-ups, sprint planning, retrospectives) and contribute to continuous improvement of the delivery process.
Design and implement modular microservices or serverless components; manage service discovery, fault tolerance, and inter-service communication patterns.
Monitor application health using telemetry, logs, and metrics; set up alerts and dashboards to proactively detect degradation or outages.
Estimate effort for tasks and features; identify technical debt and prioritize refactors that increase development velocity and reduce long-term risk.
Implement localization/internationalization features where required and ensure code supports multi-region deployment patterns.
Mentor junior developers through pair programming, technical guidance, and structured feedback to build team capability and retention.
Collaborate with DevOps or platform teams to containerize applications using Docker, manage orchestration with Kubernetes, and optimize cloud resource usage.
Participate in prototyping and POCs to vet new technologies and frameworks; present findings and recommend adoption strategies.
Contribute to product strategy by identifying feasibility constraints, proposing alternative solutions, and estimating technical risk.
Ensure data integrity and privacy by following data handling policies, encryption standards, and access controls in code and database designs.
Coordinate release activities with QA and product owners, perform release validation, and support hotfixes and rollbacks when necessary.
Drive performance optimization initiatives by profiling applications, refactoring hotspots, and implementing caching strategies.
Maintain and modernize legacy codebases by extracting modules, writing tests, and documenting replacement strategies to reduce continuity risk.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
Assist in onboarding new team members by setting up development environments and reviewing initial contributions.
Engage with stakeholders to clarify acceptance criteria and verify feature behavior during UAT.
Maintain an inventory of technical dependencies and third-party licenses; propose upgrades and replacement plans.
Conduct performance and security benchmarks for dependencies and runtime environments.
Participate in cross-team initiatives to standardize libraries, coding patterns, and deployment practices.
