Role Summary

The Appian Architect owns the end-to-end technical design and delivery quality of Appian solutions built for Singapore Government agencies and statutory boards. The role combines deep platform expertise with the judgement to translate public-sector policy, data-governance, and security requirements into a compliant, scalable Appian architecture. The Architect is the primary technical authority during solutioning, design governance reviews, and production go-live, and acts as the escalation point for complex integration, performance, and security issues across the engagement.

Key Responsibilities

Lead solution architecture and design for Appian applications delivered to Singapore Government/Statutory Board clients, ensuring alignment with agency IT policies and Smart Nation / client's technical standards.
Define and govern the Appian data model, CDT structures, and RDBMS design in accordance with data classification and data-sharing requirements applicable to public-sector systems.
Own the security architecture of Appian solutions, including group- and rule-based security models, records-level security, and role-based access control aligned to agency policy.
Design and review SAIL interfaces, process models, Records, Sites, and Task Reports for usability, performance, and maintainability at scale.
Architect external integrations (Integration Objects, connected systems, web services/APIs) with government and whole-of-government shared platforms, ensuring compliance with agency network and data-exchange controls.
Direct the design, build, and governance of custom Appian plug-ins where out-of-the-box capability is insufficient.
Lead requirements workshops with government stakeholders and translate policy/business requirements into an end-to-end Appian solution blueprint.
Own Appian environment strategy, installation, and server-side configuration guidance across Dev/Test/Staging/Production tiers, typically hosted on Government Commercial Cloud (GCC) or agency-managed infrastructure.
Establish and enforce Appian DevOps practices (application packaging, deployment pipelines, version control, environment promotion) suited to public-sector change-management and audit requirements.
Run and interpret Appian HealthCheck results, log analysis, and performance diagnostics, and drive remediation of findings before audit or go-live.
Provide technical governance in Architecture Review Board (ARB) sessions, security reviews, and Vulnerability Assessment/Penetration Testing (VAPT) cycles required for government system deployment.
Mentor Senior Developers and Developers on the team and enforce Appian and agency-specific coding/design standards.

Required Skills & Experience

At least 5+ years of hands-on Appian development/architecture experience and 10+ years overall in IT.
Proven experience with Appian 20.x and above, including newer platform capabilities (Process HQ, AI Skills/Document extraction, Robotic Process Automation, as applicable).
Strong understanding of defining and managing Appian security groups, role maps, and security inheritance.
Advanced SAIL scripting skills for complex, high-volume interfaces.
Deep experience building and using CDTs, including nested and versioned data types.
Extensive experience with Task Reports, Records, and Sites design for enterprise-scale deployments.
Proven track record of external system integration using Integration Objects, connectors, and web services/APIs.
Experience developing and governing custom Appian plug-ins.
Sound knowledge of relational data modelling and RDBMS concepts (Oracle, PostgreSQL, or SQL Server, commonly used in government environments).
Strong grasp of Appian best practices, design patterns and platform guidelines published by Appian.
Ability to gather requirements directly from government business owners and produce an end-to-end Appian solution.
Working understanding of Appian installation, server-side configuration, and environment architecture.
Ability to analyse and troubleshoot issues from Appian and application server log files.
Familiarity with Appian DevOps tooling and CI/CD adoption for enterprise deployments.
Experience running and acting on Appian HealthCheck reports.

Certifications

Appian Certified Associate Developer.
Appian Certified Senior Developer.
Appian Certified Lead Developer.
Additional certifications in cloud (AWS/Azure/GCC) or security (e.g., CISSP, CISA) are advantageous given public-sector cloud and audit requirements.

Singapore Public Sector — Specific Requirements

Prior experience delivering IT projects for Singapore Government ministries, agencies, or statutory boards is strongly preferred.
Working knowledge of Singapore's public-sector IT governance and security frameworks (e.g., Government Instruction Manuals such as IM8, and prevailing Smart Nation technical guidelines) as they apply to Appian deployments.
Understanding of Government-on-Cloud (GCC 2.0) hosting models and the associated network segregation, data-residency, and change-control requirements.
Experience supporting security assessments, VAPT remediation, and audit evidence preparation typically required before go-live on government systems.
Awareness of data classification schemes (e.g., Restricted/Confidential/Sensitive handling) and their implications for Appian data model and integration design.
Willingness to work on-site at government premises where required, including in environments with restricted internet/device access.

Soft Skills & Client Engagement

Excellent communication skills and the ability to engage confidently with senior government stakeholders and steering committees.
Strong client-facing skills, including experience presenting architecture decisions and trade-offs to non-technical audiences.
Ability to manage competing priorities across multiple government stakeholders and vendors.
Strong written communication for architecture documents, security submissions, and audit responses.
