The Role: Senior Software Engineer (Cloud, Data & APIs) This is a hands‑on, hybrid role designed for builders. As a Software Engineer, you’ll be part of a deeply technical team solving real‑world data and infrastructure challenges for our enterprise clients, from scaling streaming pipelines and integrating APIs to designing high‑availability cloud systems.

You’ll have the opportunity to lead technical direction, mentor teammates, and rotate across domains that expose you to new tech, use cases, and industries. We're not just hiring you for a project. We’re investing in your long‑term growth.

If you love writing clean code, collaborating cross‑functionally, and designing systems that make a real impact, you’ll thrive at Tactable.
