What you’ll do day-to-day

You’ll design, build, and maintain the core systems that power Wisable’s internal platform, with an emphasis on reliability, scalability, and automation. Key responsibilities:

  • Develop and maintain high-quality, performant backend applications primarily in Python, with ReactJS used as needed for data-driven interfaces.
  • Design and evolve system architecture, including database schemas, service boundaries, and data flows across internal systems and external integrations.
  • Own PostgreSQL-based data models, including schema design, migrations, performance optimization, and data integrity for complex workflows.
  • Build and maintain integrations across core infrastructure components such as CRMs, document systems, cloud services, and internal tools.
  • Develop and maintain AI-powered systems, including RAG pipelines that integrate structured and unstructured business data into production workflows.
  • Improve the reliability, observability, and robustness of both AI-driven and non-AI systems as the platform scales.
  • Design and implement automation and RPA-style workflows to reduce manual effort and improve operational efficiency.
  • Optimize application performance, system latency, APIs, and overall availability.
  • Apply best practices for security, with particular focus on handling sensitive financial and business data.
  • Participate in code reviews, testing, and continuous integration to maintain a high standard of code quality.
  • Collaborate closely with non-technical leadership to gather requirements, explain technical tradeoffs, and support business decision-making.
