Why This Job is Featured on The SaaS Jobs
CorePlan sits in a distinctive part of the SaaS ecosystem: product-led, cloud-native software built for operationally complex industries where uptime and data integrity matter. A Full Stack Tech Lead in this setting is positioned at the intersection of real-time workflows, large relational datasets, and platform engineering, translating messy field realities into durable SaaS primitives. The remit spans architecture, APIs, and delivery, which is a strong signal that the platform is mature enough to need standards and direction, not just feature output.
For a long-term SaaS career, the role offers repeated exposure to the problems that scale with adoption: performance tuning, observability, CI/CD discipline, and evolving service boundaries without disrupting customers. Leading a small team while remaining hands-on also builds the core “tech lead” muscle in SaaS: making trade-offs visible, reducing operational risk, and aligning engineering decisions with product outcomes across web and mobile surfaces.
This role suits an experienced engineer ready to own technical quality end to end and to coach others through design and execution. It will appeal to someone who enjoys backend depth but wants full stack context, and who prefers clear accountability, pragmatic architecture, and close collaboration with product and design in a B2B SaaS environment.
