  • Break complex problems into incremental deliveries, identify technical risks early, and contribute to estimation and planning with a focus on predictability.
  • Partner closely with Product Managers and Designers to develop technically viable solutions, balancing technical investment, complexity, and customer value.
  • Translate technical concepts and decisions clearly to non-technical stakeholders and help align engineering priorities with product and business objectives.
  • Support production operations and critical incidents following a “you build it, you run it” mindset, continuously improving MTTR, availability, and system resilience.
  • Develop AI-powered solutions and integrate AI models where they can improve processes, product capabilities, or operational efficiency.

  • Experience designing and developing scalable RESTful APIs, with strong knowledge of Git and Linux.
  • Familiarity with Artificial Intelligence, including LLM integrations, AI frameworks, or data-driven product capabilities.
  • Experience making architectural decisions in environments involving trade-offs between performance, cost, security, scalability, and maintainability.
  • Sufficient frontend knowledge to review architectural decisions, discuss technical trade-offs, and ensure effective backend/frontend integration.
  • Strong technical leadership and mentoring abilities, with autonomy, proactive ownership, critical thinking, and a results-oriented mindset.
  • Excellent communication skills and the ability to collaborate effectively with technical and non-technical stakeholders.
  • Experience with system integrations, third-party APIs, webhooks, CRMs/ERPs, or integration platforms is a strong plus.
  • Experience supporting corporate or enterprise accounts, gathering specific requirements, and adapting solutions while preserving long-term maintainability is desirable.
