About Perceptyx At Perceptyx, we help organizations see the employee experience more clearly. Our AI-powered continuous listening platform enables leaders to understand what matters most to their people and turn insights into meaningful action. We partner with the world's most innovative enterprises to drive transformation across engagement, performance, wellbeing, DEI, and change initiatives. The Role We're hiring a Senior Software Developer for our Core Platform team, the team that builds the shared foundations every other engineering team at Perceptyx builds on top of. This is an individual contributor role with real organizational impact. Platform engineering work is different from product engineering work: requirements are rarely handed to you fully formed, and the right answer is often "it depends on three other teams." We need someone who's genuinely curious about how the pieces fit together, comfortable operating without a finished spec, and willing to form and defend an opinion on where the line between "platform" and "product" should sit — then go make that case directly to the product engineering teams building on top of your work. You'll also help shape how Perceptyx builds software in an AI-driven world. As AI-assisted development rapidly changes how software is written, tested, and delivered, we're intentionally bringing in engineers who can lead that transition, coach others, and raise the technical bar across the team. This role partners closely with engineering leadership and serves as a force multiplier across the organization — setting standards, introducing modern practices, and influencing how we design, build, and scale the platform What You’ll Do Own the Platform Boundary: Work directly with Product engineering teams to define what should live in the platform versus in individual products, bringing a clear point of view — not just implementing what's requested, but shaping what gets built and why. Navigate Ambiguity: Take on problems that arrive as open questions rather than finished requirements — competing constraints from multiple teams, unclear ownership, evolving priorities — and drive them to a sound technical direction. Lead and Multiply: Act as a senior technical leader on the Platform team, coaching engineers and elevating modern software engineering and AI-first development practices across the organization. AI-Driven Development: Champion the adoption of AI-assisted development, guiding the team on how to effectively and safely use AI for coding, testing, and delivery as tools and models rapidly evolve. Architect and Build: Design, develop, and evolve scalable, high-performance frontend and backend systems and shared services using a modern full-stack approach. Own Reliability: Set the operational bar for the platform every other team depends on: clean code, thoughtful reviews, test-driven development, and the instrumentation and runbooks that make failures visible and…
