Software Developer (Junior / Mid)

About the role

You will build and maintain integrations with partner REST APIs, write backend services in PHP (Laravel) on MySQL, and handle transaction flows where every record must be exact. You will investigate production issues, support reporting and data pipelines, work with internal product teams to agree API contracts, review code through Git pull requests, and keep technical docs up to date. The team is small, so your work ships to production and you see what it does.

Key responsibilities

• Build and maintain integrations with partner REST APIs: read their specs, map their data to our internal contract, and handle their errors and edge cases.
• Write backend services in PHP (Laravel) on MySQL.
• Handle transaction flows where every record must be exact: retries, refunds, reversals and currency conversion.
• Investigate production issues: trace a request through logs and databases, find the cause, and fix it.
• Support reporting and data pipelines (batch jobs, ClickHouse, event streams).
• Work with internal product teams to agree API contracts and hand over finished features.
• Review teammates' code and have yours reviewed, through Git pull requests.
• Keep technical docs up to date.
