Core Responsibilities

Primary Functions

  • Design, develop, and maintain responsive, accessible, and performant web user interfaces using modern front-end frameworks such as React, Angular, or Vue, ensuring consistent behavior across browsers and devices.
  • Implement robust server-side application logic and APIs using Node.js, Python, Java, or .NET, following RESTful and/or GraphQL design principles to support single-page applications and mobile clients.
  • Collaborate closely with Product Managers and UX/UI Designers to translate wireframes and business requirements into technical specifications, interactive prototypes, and production-ready features.
  • Build and maintain relational and NoSQL data models (PostgreSQL, MySQL, MongoDB, DynamoDB), including schema design, query optimization, indexing, and migration strategies.
  • Create, document, and version APIs and SDKs; enforce contract-driven development and API versioning to support backward compatibility and third-party integrators.
  • Write comprehensive automated tests (unit, integration, end-to-end) using tools like Jest, Mocha, Cypress, or Playwright to ensure code quality and reduce regressions.
  • Implement CI/CD pipelines using GitHub Actions, GitLab CI, Jenkins, or CircleCI to automate builds, tests, code quality checks, and deployments to staging and production environments.
  • Containerize applications and manage container orchestration with Docker and Kubernetes for scalable, fault-tolerant deployments and consistent developer workflows.
  • Optimize application performance at front-end and back-end layers (code splitting, lazy loading, memoization, caching, CDN configuration, database query tuning), measured against SLAs and performance budgets.
  • Enforce secure coding practices: input validation, authentication and authorization (OAuth, JWT), proper session management, encryption, and remediation of OWASP vulnerabilities.
  • Instrument applications with logging, metrics, and tracing (Prometheus, Grafana, ELK/EFK, OpenTelemetry) to monitor health, diagnose issues, and meet SLOs.
  • Lead code reviews, mentor junior engineers, shape coding standards and best practices, and promote a collaborative engineering culture focused on continuous improvement.
  • Integrate third-party services and cloud-native features (AWS/GCP/Azure services such as S3, Lambda, Cloud Functions, Secrets Manager) to accelerate feature delivery and reduce operational overhead.
  • Manage feature rollouts with feature flags, canary releases, and A/B testing frameworks to minimize user impact and gather data-driven insights.
  • Participate in sprint planning, backlog refinement, and agile ceremonies; estimate work, break down complex tasks, and deliver incremental value on predictable cadences.
  • Troubleshoot and resolve production incidents, perform root cause analysis, and produce postmortems with remediation plans to prevent recurrence.
  • Implement localization/internationalization strategies when applicable, ensuring string externalization, date/number formatting, and right-to-left support.
  • Collaborate with QA, security, and operations to define release readiness criteria and deploy secure, stable releases to production.
  • Maintain and improve developer tooling and internal libraries, reducing cognitive load on teams and accelerating time-to-market for new features.
  • Evaluate and recommend new technologies, libraries, and architectures that align with business goals, scalability requirements, and team skill sets.

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.
  • Maintain technical documentation, API docs, runbooks, and onboarding guides for new developers and cross-functional stakeholders.
  • Provide estimates and technical risk assessments for proposed features and platform changes.
  • Assist in vendor evaluations and integrations, including contract and security assessments for third-party SaaS providers.
  • Conduct performance and security audits in partnership with infrastructure and security teams.
