Intern Python Backend Developer

Type: Full-time Internship (Remote)

Duration: 6 months (extend/convert based on performance)

Start: ASAP

Compensation: Paid (stipend based on skills/availability)

Location/Time: Remote; 3–4 hours overlap with Asia/Colombo (UTC+5:30)

Why this role

You won’t be “observing.” You’ll design, build, test, and ship production APIs used by real users. Tight feedback loops, code reviews, and clear standards.

What you’ll do

• Build FastAPI services (async endpoints, dependency injection, Pydantic models).
• Model data with SQLAlchemy 2.0; manage migrations with Alembic.
• Implement auth (OAuth2/JWT), roles/permissions, and rate limiting.
• Integrate PostgreSQL/MySQL, Redis (caching/queues), and third-party APIs.
• Handle file uploads (e.g., to S3) and background jobs (Celery/RQ or FastAPI BackgroundTasks).
• Write tests (pytest + requests/HTTPX), keep coverage on core logic.
• Ship with Docker/Compose, wire basic CI (GitHub Actions), maintain OpenAPI docs.
• Add observability: structured logs, error tracking (Sentry), metrics basics.
• Participate in code reviews, follow branch strategy, and document your work.

You’ll thrive if you have

• Solid Python 3.10+ and comfort with type hints/typing.
• Working knowledge of FastAPI, Pydantic, HTTP/REST, and JSON.
• Practical SQL skills and familiarity with one RDBMS (Postgres/MySQL).
• Git fundamentals (feature branches, PRs, resolving conflicts).
• Clear written communication and the habit of asking specific questions.

Nice to have (not required)

• SQLAlchemy 2.0 (declarative, session management), Alembic.
• Redis (cache/locks/queues), Celery/RQ/Taskiq.
• Security basics (OWASP API Top-10), JWT/OAuth2 flows.
• Docker/Compose, Nginx/uvicorn-gunicorn, GitHub Actions.
• Cloud basics: AWS (S3, RDS), or GCP/Azure equivalents.
• API versioning, pagination, idempotency keys, webhooks.
• Async I/O patterns, backpressure, and performance profiling.

What you’ll work on (examples)

• Public/partner REST APIs consumed by React and Flutter apps.
• Auth & roles, audit trails, and secure file upload pipelines.
• Background processing (notifications, media processing, webhooks).
• Data dashboards endpoints (filters, search, pagination, exports).

How we work

• Issue-driven tasks with acceptance criteria; small PRs; fast reviews.
• Lint/format gate (ruff/black), pre-commit hooks, clear commit conventions.
• Weekly milestones; async check-ins; no ceremony for the sake of it.
