Software Developer and Metadata Engineer Consultant for Open Code Infrastructure (OCI)

The consultant will carry out full-stack development and operations activities across the Open Code Infrastructure (OCI) platform, including feature development, bug fixes, and dual-compatible metadata engineering for Croissant and BioCroissant standards. The role involves maintaining technical documentation and supporting deployment and operational procedures for the platform.

Responsibilities

• Implement new features and enhancements on both platforms as prioritized by the project team, covering backend logic, REST APIs, frontend interfaces, and database changes.
• Diagnose and resolve reported bugs and issues across the full stack.
• Ensure new code follows existing architectural patterns and coding standards of each platform.
• Implement and test code changes in the Croissant repository to address dual-compatibility blockers with Bioschemas, including type conflicts, name validation, and handling of keywords/citations.
• Create validator or linter rules or plugins that check both Croissant and Bioschemas expectations.
• Add unit and integration tests, fixtures, and CI hooks to prevent regressions on dual compatibility.
• Prepare minimal examples and documentation demonstrating successful dual validation (Croissant parsers + Bioschemas FAIR checks).
• Open PRs and upstream issues to the Croissant repository or maintain a clean BioCroissant extension package if upstream changes are not feasible.
• Maintain technical documentation covering architecture, deployment procedures, and API specifications.
• Document operational procedures and troubleshooting guides to facilitate knowledge transfer.

Requirements

• University degree in computer science, software engineering, information technology, or a related field OR education from a reputed college of advanced education, with a diploma of equivalent standard to that of a university degree in one of the fields above.
• At least three (3) years of progressively responsible experience in software development and documentation for the relevant technical areas below.
• Experience in full-stack development with TypeScript on both ends — Node.js services (NestJS or comparable) and a modern React framework.
• Experience with JSON / JSON-LD, schemas, and validation (e.g., Zod, JSON Schema, Croissant / BIOCroissant).
• Experience with the following technical environment; the developer will work across a single unified stack, with a small isolated Python sandbox for executing participant evaluation containers: Layer: OCI Platform (target stack). Backend: Node.js 24 LTS, TypeScript 6, NestJS 11 (modular monolith), Prisma 7, BullMQ. Eval sandbox: Python 3.x - only for the sandboxed runner that executes participant Docker images. Frontend: Next.js 16 (App Router, React Server Components, Turbopack), React 18+, Tailwind v4, shadcn/ui. Database: PostgreSQL 16 (AWS Aurora Serverless v2), Prisma migrations, multi-schema. Auth: AWS Cognito (OIDC/OAuth2), aws-jwt-verify, MFA for admin/regulator/supervisor roles. Infrastructure: AWS CDK (TypeScript), ECS Fargate, ALB, S3, SQS, ECR, KMS, WAFv2, Secrets Manager. CI/CD: GitHub Actions with OIDC role assumption (no static AWS keys); per-env deploy pipelines. Observability: CloudWatch, AWS X-Ray, OpenTelemetry, pino structured logging, Container Insights. Security tooling: Trivy, Gitleaks, CycloneDX SBOM in every PR; distroless Node base images. API contracts: OpenAPI 3.1 via NestJS Swagger module; Zod schemas shared FE/BE via @oci/shared-types. Testing: Vitest 4 (unit + integration with Testcontainers), Playwright 1.59 (E2E + a11y).
• A minimum of an intermediate level of English is required.
• Knowledge of at least one of the six official ITU languages (Arabic, Chinese, English, French, Russian, Spanish) would be an advantage.
