• Co-own the integration delivery lifecycle with product owners: discovery, design, build, testing, rollout, and continuous improvement.

• Maintain and enhance existing integrations while delivering new integrations aligned with product and business goals.

• Lead migration of Node.js integrations to Python, defining technical approach, sequencing, and quality standards.

• Monitor integration health, partnering with SREs on alerting, logging, observability, and proactive issue detection.

• Drive root-cause analysis and prevent recurring integration incidents.

• Champion integration reliability best practices, including error handling, retries, versioning, testing, and resilience patterns.

• Mentor engineers on integration patterns, API design, and operational robustness.

• Lead code reviews, contribute to architecture decisions, and set team-wide quality and maintainability standards.

• Collaborate with Product, Operations, and Engineering stakeholders to translate evolving business needs into robust technical solutions.

Requirements

• 5+ years of software engineering experience with ownership of complex systems and technical leadership.

• Expert proficiency in Python and production-grade integration development.

• Strong experience designing and operating system integrations via APIs, including authentication, versioning, retries, and error handling.

• Proven ability to monitor, troubleshoot, and optimize integration performance in live environments.

• Experience in agile, fast-paced SaaS or startup settings.

• Demonstrated capability to design or contribute to highly available, horizontally scaling systems.

• Comfortable leading technical migrations or major refactors end-to-end.

• Deep system design and integration architecture expertise with a focus on scalability, security, and maintainability.

• Strong problem-solving, analytical thinking, and operational excellence mindset.

• High-quality engineering practices: clean code, documentation, and thorough testing.

• Excellent collaboration, cross-functional communication, mentorship, and team influence skills.

Benefits

• Supportive, growth-focused team culture that invests in your personal and professional development.

• Flexible working hours with hybrid or fully remote options.
