About the Role

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
