Backend Engineering Intern (Python, FastAPI)

Scanwick reads a borrower's bank and wallet statements, joins every account into one position, and gives Nigerian lenders the evidence behind every figure, before the loan and, with the borrower's consent, after it. No credit score and no automated decision: the lender decides.

WHAT YOU WILL DO

• Build and fix backend features in Python (FastAPI), with PostgreSQL, SQLAlchemy and Alembic, and background jobs on Celery and Redis.
• Write a test that proves every change, and run the full test suite before you ask for review.
• Work on real production code through pull requests, each one reviewed by our CTO before it is merged.
• Treat people's financial data with care: each lender sees only its own borrowers, nothing is read without consent, and nothing sensitive is logged.
• Explain your work clearly in writing, and say plainly when something is not finished or not understood.

WHAT YOU NEED

• Python you have written yourself, in a project you can walk us through line by line.
• Working knowledge of SQL and of building or using HTTP APIs.
• Git, and writing automated tests (pytest or similar).
• Care with money and data: you know why money is not stored as a decimal float, and why a missing figure is not zero.
• Honesty about how you use AI tools: use them if you like, but you must understand, test and stand behind every line you submit.
• Reliable internet and enough time each week to finish what you take on (agreed with you before you start).

GOOD TO HAVE

• FastAPI, async Python, Celery or Redis.
• Anything in fintech, payments, open banking or data protection.
• Experience reading bank statements, or building for Nigerian users.

WHAT WE OFFER

• Real, owned work on a live product, not practice exercises.
• A weekly call of at least 30 minutes with the founder and CTO, and written review of every piece of work you submit.
• Remote, with hours you set within what we agree.
• A certificate of internship at the end, stating your role, dates and the work you actually did, and an honest reference on request.
• Outstanding interns may be offered a staff role.

TERMS
Unpaid internship, 4 months, remote, Nigeria. No salary, stipend or equity during the internship.

HOW TO APPLY

1. Apply with: your GitHub (or the code of one project you built), two or three lines on the hardest bug you fixed, and how you use AI tools when you code.
2. Shortlisted candidates do a short practical task built from the kind of problems we solve. send your application and resume to [email protected]
