This Technical Architect role sits at a core SaaS inflection point: turning a product platform into repeatable, enterprise-grade outcomes in customer environments that still run on legacy systems. Klir is positioned as an operational data hub, and the work described reflects a SaaS company selling into complex, regulated infrastructure where integrations, identity, and auditability determine adoption as much as features do.
For a SaaS career, the long-term value is in building the muscle of post-sales technical delivery at enterprise depth. The remit spans integration patterns, large data migrations, security reviews, and cross-functional governance, which are durable competencies across B2B SaaS categories. It also reinforces a product-minded approach to delivery through reference architectures and implementation playbooks, experience that translates into solution architecture leadership or technical ownership of customer onboarding at scale.
About Klir
We are hiring to make water better!
For too long, utilities have had to manage water through fragmented systems, siloed data and workflows held together by institutional memory. As costs rise, teams shrink and operational decisions demand real time clarity, connected data is no longer a nice to have. It is essential.
At Klir, our mission is simple: Make Water Better.
We believe the future of water is generative, built on connected data, clear workflows and operational continuity. Klir is the Operational Data Hub that unifies sampling, monitoring, permits, backflow and reuse into one connected view of the utility. When data, systems and decisions flow through a single hub, teams gain the confidence, control and time they need to focus on what actually moves water forward.
Backed by Insight Partners, Bowery Capital and Spider Capital, Klir is one of the fastest growing companies in the digital water space. Utilities consistently tell us that Klir has transformed the way they work.
As we enter our next phase of growth, we are hiring a Customer-Facing Technical Architect to partner closely with our customers, translating complex technical needs into clear, scalable solutions. This role will help establish strong ways of working across customer engagements, while championing technical excellence and a high-performance culture both internally and externally.
Location: Hybrid based in Dublin with 2 days in office per week.
