Grow With Us
We are looking for a Senior Software Solutions Engineer in Professional Services (PS) to join our growing team. In this role, you will own the design, development, and delivery of complex technical integrations between our platform and enterprise client systems. You'll operate at the intersection of deep software engineering and customer partnership — leading integration architecture decisions, mentoring junior engineers, and driving technical standards across the PS organization.
The majority of your time is spent writing code, architecting scalable solutions, and solving genuinely hard technical problems. You'll bring an AI-native mindset to everything you build — leveraging LLMs, automation, and modern AI tooling to deliver faster, smarter outcomes for clients and the team. You'll work directly with enterprise clients and internal stakeholders to translate complex business requirements into production-grade software, with direct, visible impact on customer retention and satisfaction.
