Here at Appian, our values of Intensity and Excellence define who we are. We set high standards and live up to them, ensuring that everything we do is done with care and quality. We approach every challenge with ambition and commitment, holding ourselves and each other accountable to achieve the best results. When you join Appian, you'll be part of a passionate team dedicated to accomplishing hard things, together.

Are you looking to combine your passion for technology with your penchant for strategic problem solving? Appian Customer Success is obsessed with great customer outcomes. We deliver mission-critical business impact fast and are directly responsible for partnering with our customers to bring their best ideas to life. Joining the Customer Success team provides you with the support and growth you need to strengthen and evolve your consulting skills while driving next-generation, AI-powered digital transformations.

We are seeking a Principal Technical Consultant (Public Sector) to join our Customer Success team. In this role, you will be engaging with our customers post-sales to develop software solutions on the Appian platform. These applications help companies drive digital transformation and competitive differentiation. Your primary responsibility will be to work throughout the entire project life‑cycle to define, design, develop and implement custom software and AI solutions using Appian's low‑code platform for our commercial clients.

This includes working within an agile environment to understand our client's business processes and technical needs, launch new relational data models in production, and develop APIs to integrate with multiple systems. You'll brainstorm AI use cases and implement Appian's AI tools by applying retrieval augment generation (RAG), agentic workflows, prompt engineering and the latest generative models as part of transforming how customers run their organization.

You will also collaborate with client's technical teams and business users as needed throughout the entire software and development life cycle and drive adoption by empowering clients to become self‑sufficient with building process applications on their own.

This role is based at our HQ in McLean, VA. Appian was built on a culture of in‑person collaboration, which we believe is a key driver of our mission to be the best. Employees hired for this position are expected to be in the office 4‑5 days per week to foster that culture, ensure we thrive through shared ideas and teamwork, and maximize opportunities to connect with the exceptional people across Appian.

While working in‑person with customers is our main priority, we also believe the office environment enables more opportunities to celebrate wins, collaborate effectively, and build strong relationships across teams.
