• API Engineering: Architect and implement high-performance RESTful APIs and GraphQL schemas, integrating external third-party services and downstream systems using JSON-based payloads.
• Database Design & Management: Model, optimize, and manage NoSQL databases (primarily MongoDB) as well as relational databases (e.g., PostgreSQL, MSSQL) for query performance and data integrity.
• System Administration & Tooling: Develop, deploy, and debug applications directly in Linux/Unix environments.
• Code Quality & Mentorship: Drive clean architecture, comprehensive unit/integration testing, and code reviews across Git-based workflows.
• Cross-Functional Collaboration: Partner with product managers, QA, and DevOps engineers within an Agile/Scrum framework to deliver sprint commitments predictably.

Required Technical Skills & Qualifications

• API Technologies:
• Demonstrated expertise in designing, securing, and documenting RESTful APIs.
• Practical experience implementing and consuming GraphQL APIs.
• Advanced proficiency in handling complex JSON parsing, data serialization, and API integrations.
• Databases:
• Strong hands-on experience with MongoDB (aggregation framework, indexing, schema design).
• Solid working knowledge of relational databases (e.g., PostgreSQL, MySQL) alongside ORM/ODM libraries (e.g., SQLAlchemy, MongoEngine, Beanie).
• Environment & Version Control:
• Comfortable operating, scripting, and troubleshooting in Linux environments.
• Advanced proficiency with Git workflows (branching strategies, PR reviews, conflict resolution).
• Process & Delivery: Well-versed in Agile/Scrum methodologies, sprint planning, and test-driven development practices.

Good-to-Have Skills (Preferred)

• Containerization & Orchestration: Hands-on experience containerizing applications using Docker and deploying/managing workloads on Kubernetes or Red Hat OpenShift.
• CI/CD: Experience configuring automated build, test, and release pipelines using Jenkins or similar platforms.
• Infrastructure as Code (IaC): Familiarity with infrastructure automation and provisioning using Ansible or Terraform.
• Observability & Telemetry: Practical exposure to application performance monitoring (APM), centralized logging, and metrics stacks (e.g., Prometheus, Grafana, OpenTelemetry, ELK, Datadog).

Preferred Soft Skills

• Strong technical communication skills with the ability to explain complex architectural decisions to non-technical stakeholders.
• Proven mentorship abilities to guide junior and mid-level engineers.
• Pragmatic problem-solver comfortable owning features end-to-end.
