Role Overview

Simpaisa's Solution Engineers are the people who build the product. This role is not a support position — it is a core engineering role responsible for implementing payment features, operator integrations, and platform improvements that process millions of transactions across 7 markets.

You will work within a squad alongside a Product Manager and Tech Lead, following the Simpaisa SDLC v2.0. You write the code, write the tests, participate in architecture reviews, and own the features you build through to production. "Threw it over the wall to ops" is not a pattern we use here.

Key Responsibilities

  • Implement software components according to design specifications, acceptance criteria, and fund flow diagrams produced by Product Managers and Solution Architects.

  • Write unit and integration tests for all code (80% coverage target on changed files).

  • Participate in code reviews; provide constructive feedback and accept it.

  • Write and maintain technical documentation — ADR contributions, integration guides, API specs.

  • Configure and test feature flags for all user-facing or operator-facing changes.

  • Contribute to deployment readiness: monitoring, alerting config, rollback testing.

  • Security: Awareness of OWASP top 10; secure coding practices; no secrets in code.

  • Payments (preferred): Experience with payment systems, fintech APIs, or financial data is a strong advantage — not a requirement.

  • Agile: Experience working in structured agile delivery — standups, sprint planning, retrospectives, Definition of Done.

  • Communication: Clear written communication for code reviews, PRs, and documentation.

General Requirements

  • Bachelor's degree in Computer Science, Engineering, or a related field.

  • 3+ years of experience in software development with production systems.

  • Demonstrated experience building and integrating multi-service systems.
