Core Responsibilities

Primary Functions

Gather and refine application requirements by partnering with business stakeholders, product owners, and subject-matter experts, translating functional needs into technical specifications and user stories that drive development priorities.
Design, develop, and unit-test new application modules, features, and integrations using enterprise languages and frameworks (e.g., Java, C#, .NET Core, JavaScript/TypeScript, Python) following secure coding standards and best practices.
Build and maintain RESTful and SOAP APIs, microservices, and middleware connectors to ensure reliable data exchange between ERP/CRM systems, third-party SaaS platforms, and internal services.
Implement database design and data access logic, author complex SQL and stored procedures, optimize queries and indexes for performance, and maintain data integrity across relational databases (Oracle, SQL Server, PostgreSQL).
Troubleshoot and resolve production application incidents, perform root cause analysis, and implement corrective and preventive measures to reduce recurrence and improve system stability.
Participate in sprint planning, backlog grooming, and Agile ceremonies; estimate development tasks, track progress, and deliver features iteratively with frequent stakeholder demo and feedback loops.
Collaborate with DevOps and infrastructure teams to automate builds, deployments, environment provisioning and configuration using CI/CD pipelines (e.g., Jenkins, Azure DevOps, GitHub Actions), containers (Docker) and orchestration (Kubernetes).
Perform code reviews and enforce code quality standards, automated testing best practices, and maintainable architecture to improve reliability, readability, and reuse across the application portfolio.
Integrate authentication, authorization and security controls (OAuth, SAML, RBAC), apply secure coding principles and conduct regular vulnerability remediation and dependency patching.
Develop and maintain technical documentation including design diagrams, API contracts, runbooks, deployment guides, and release notes to support knowledge transfer and operational readiness.
Build automated unit, integration, and regression tests and collaborate with QA engineers to incorporate automated test suites into CI pipelines to ensure high-quality releases.
Optimize application performance and scalability by profiling code, tuning application servers, caching strategies, and database queries, and recommending architecture improvements where needed.
Lead configuration, customization, and enhancement efforts for packaged applications (ERP, CRM, HRIS) including extension development, scripting, and integration adapters.
Manage application releases and change control: coordinate release activities, perform deployment validation, monitor post-release health, and roll back if required to ensure minimal business disruption.
Implement logging, monitoring, and alerting solutions (e.g., ELK, Splunk, Prometheus) to maintain operational visibility, detect anomalies, and support proactive incident management.
Develop and maintain data integration and ETL processes to support reporting, analytics, and data warehouse synchronization across disparate systems and formats.
Support cross-functional projects by providing technical input for feasibility assessments, architecture decisions, cost estimations, and MVP planning for digital transformation initiatives.
Provide production support on a rotating or on-call basis, triaging incidents, implementing hotfixes, and communicating impact, resolution status, and mitigation plans to stakeholders.
Mentor and coach junior developers and interns, sharing knowledge on coding standards, troubleshooting techniques, and professional development practices.
Conduct impact analysis for proposed changes, identify dependencies and risks, and design migration strategies including data migrations and schema evolution with minimal downtime.
Ensure compliance with data protection, privacy, and regulatory requirements by incorporating auditing, encryption, and retention controls into application designs.

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 vendor evaluations, proof-of-concepts and third-party integration assessments for new technologies and SaaS products.
Provide user training, prepare user manuals, and develop knowledge base articles to improve adoption and reduce support tickets.
Help estimate project costs, timelines and resource requirements for new application initiatives.
Participate in disaster recovery planning, periodic failover tests, and business continuity exercises related to applications under scope.
