Description

Do work that matters We’re building tomorrow’s bank today—reimagining how intelligent workflows, automation, and engineering come together at scale. We’re looking for a Staff Software Engineer with deep Appian expertise and strong engineering fundamentals—someone who treats Appian as a true engineering platform, not just a workflow tool. You’ll design and build mission-critical solutions that power core business processes, while integrating into a broader ecosystem where Python and modern engineering practices are strategic. Key Responsibilities Design and build scalable, secure Appian applications across SAIL, process models, records, integrations, and data layers Write clean, efficient, and maintainable code within Appian, leveraging expression rules, APIs, and reusable components Apply software engineering principles (modularity, performance, testability) to low-code solutions Define and implement architecture patterns for workflow, integration, and system design Solve complex workflow and orchestration challenges across high-volume, mission-critical systems Integrate Appian with external platforms and services, including Python-based ecosystems Drive engineering excellence through code reviews, CI/CD, DevSecOps, and observability practices Mentor engineers and uplift capability across the team Required Experience Extensive experience building Appian BPM applications (SAIL, process models, records, integrations, data stores, security) Strong understanding of Appian architecture, performance optimisation, and platform best practices Proven ability to design and deliver complex workflow and case management solutions Demonstrated coding capability and problem-solving ability within Appian and general-purpose programming contexts (e.g. APIs, integrations, scripting) Proven ability to design, explain, and defend technical solutions across workflows, integrations, and system architecture Experience working beyond configuration, applying engineering principles to solve problems involving performance, scalability, and integration Solid understanding of software engineering fundamentals—data structures, system design, and clean code practices Experience working in cloud environments (AWS preferred) Ability to operate at a Staff Engineer level—owning design, influencing architecture, and leading technical decisions Bachelor’s degree in Computer Science, Engineering or a related field, or equivalent practical experience Desired Skills Experience integrating Appian with Python-based services or platforms Familiarity with general-purpose programming (e.g. Python) and when to extend beyond low-code platforms Experience with event-driven architectures and microservices patterns Exposure to CI/CD pipelines, DevSecOps, and production observability Experience in banking, financial services, or other regulated environments Strong communication skills and ability to collaborate across technical and business teams If this sounds like you, apply now!
