Job description

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.

Appian Customer Success is obsessed with delivering exceptional customer outcomes and mission-critical business impact at speed. Our team acts as the elite consulting arm of Appian, partnering directly with the world’s largest commercial clients to bring their most ambitious ideas to life. By joining this high-performance team, you will establish a world-class foundation in professional consulting while directly accelerating global adoption of our AI-Powered Process Automation platform.

As a Consultant at Appian, you won’t just write code - you will architect modern business transformations. This role offers an unprecedented opportunity to sit at the intersection of business strategy and technical innovation. Instead of being pigeonholed into isolated legacy components, you will own the end-to-end delivery of highly visible, custom software solutions. You will work side-by-side with client executives to solve complex workflow problems, build robust integrations, and empower enterprise teams to achieve Enterprise-Grade Orchestration.

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.

What You’ll Do

• Architect & Implement: Design, develop, and deploy robust, custom automation solutions throughout the entire project lifecycle utilizing Appian’s AI-Powered Process Automation platform.

• Integrate Ecosystems: Build seamless data connections and scalable APIs to integrate multiple external enterprise systems using REST, SOAP, and JDBC connections.

• Engineer Data Models: Launch new relational data models in production environments and optimize database design through sophisticated SQL development.

• Agile Delivery: Partner within cross-functional teams using Agile methodologies (sprints, stand-ups, pair programming) to rapidly deliver high-value features.

• Empower Clients: Collaborate closely with client technical teams and business stakeholders, driving platform adoption and training users to become self-sufficient.

Required Qualifications

• Degree: Bachelor of Science or Bachelor of Arts degree in Computer Science, Engineering, Information Systems, Mathematics, or a closely related technical field.

• Experience: 1+ years of hands-on experience in software development or technical implementation consulting.

• Core Engineering: Proven track record with Object-Oriented Programming (OOP), database design, and SQL (writing complex queries, joins, and views).

• Requirements Gathering: Demonstrated ability to analyze client business processes and translate them into functional and technical system requirements.

• Mobility: Willingness to travel up to 20% to support customer engagements and on-site collaboration.

• An Active Government Clearance (Top Secret or higher, without any limitations) is required for this opening, with the ability and willingness to perform work within cleared facilities (SCIF work is required)

Preferred Qualifications

• Familiarity with modern cloud architecture and environments, including Amazon Web Services (AWS), Google Cloud, or Elastic Containers.

• Exposure to Artificial Intelligence (AI), Machine Learning, Analytics, and automated test suites within a continuous integration framework.

The base salary range provided represents a good faith and reasonable estimate of the range at the time of posting. In addition to the base salary, this position is eligible for a government clearance differential. Actual compensation will be dependent on a number of factors including, but not limited to, the candidate’s relevant work experience, qualifications, internal peer equity, and market and business conditions that exist when extending an offer. A discretionary bonus may be awarded in recognition of individual and company performance.

In addition, Appian provides generous benefits offerings that include a 401(k) plan with company match, flexible time off, paid parental leave, medical, dental, and vision plans, life insurance, disability insurance, wellness programs, flexible spending accounts, heal
