[Remote] Junior Software Engineer
Note: The job is a remote job and is open to candidates in USA. Lumanu is a company that focuses on fintech solutions, and they are seeking a Junior Software Engineer to join their backend team. The role involves writing backend features, working on the data model and API, and maintaining integrations with fintech partners while ensuring the security of sensitive data.
Responsibilities
- Write backend features in TypeScript on AWS Lambda, backed by Postgres and Hasura GraphQL
- Work on the data model and API: writing migrations, adjusting Hasura permissions, running GraphQL codegen
- Help build and maintain integrations with our fintech and compliance partners
- Learn how we handle sensitive data like tax IDs, identity documents, and payment details, behind encryption and tight access controls
- Pitch in on the logic behind global payouts, W-9/W-8 collection, tax validation, and 1099s
- Help keep things healthy in production with OpenTelemetry, Sentry, and Pino
- Write tests that actually catch bugs (Jest, plus Playwright for end-to-end)
- Build alongside product and frontend engineers in a Next.js app
Skills
- You've written real code, whether through a degree, a bootcamp, an internship, or projects you built yourself. Call it 0 to 2 years in
- You know your way around TypeScript or JavaScript and Node, and you want to get good at it
- You understand the basics of databases and SQL. Postgres is a plus, not a must
- You've built or called an API before. If GraphQL is new to you, no problem; curiosity beats mastery here
- You're careful. When money and someone's tax data are on the line, asking a question beats guessing
- You can explain your thinking, in code and in writing
- You like feedback and want to get better at the craft
- Any hands-on time with AWS or serverless
- A rough grasp of auth (JWTs, OAuth) or handling sensitive data
- An interest in fintech: payments, tax, banking, KYC, moving money around

- Curiosity about building for many countries at once, with different currencies and languages
