Senior Application Developer (VB.NET)

Fusang is seeking a Senior Application Developer (VB.NET) to build and enhance our proprietary corporate secretarial and client accounting systems used across our global offices. This is first and foremost a hands-on coding role—you will be writing high-quality, maintainable VB.NET and MS SQL Server code every day. It is not a business analyst position.

What makes it different from a typical developer role is that we expect you to genuinely understand the business workflows behind the systems you build: how work actually flows, where it is slow, manual, or error-prone, and how to automate and optimise it—leveraging AI both in how you write software and in the solutions you deliver.

In short, a strong engineer who thinks about the business, not just the code.

Key Responsibilities

Work closely with business users across corporate secretarial, client accounting, and operations teams to deeply understand how their work actually flows—the steps, the hand-offs, the pain points, and the outcomes that matter—before deciding what to build Automate & Optimise with AI: Identify manual, repetitive, or error-prone processes and design solutions that use AI and automation to streamline them—measurably improving speed, accuracy, and the day-to-day experience of business users Solution Design & Requirements Translation: Partner with the Business Analyst and business users to translate business needs into practical technical solutions, weighing trade-offs and recommending the right approach rather than simply taking orders Application Development & Enhancement: Design, develop, and maintain well-structured, testable, and efficient VB.

NET code for our in-house application systems Database Design & Optimisation: Work with MS SQL Server including database design, query optimisation, and administration to ensure system performance and reliability Legacy Modernisation: Maintain and enhance existing VB.NET applications while identifying and driving opportunities to modernise, simplify, and automate them Production Support: Address and resolve production issues and inquiries from business users in a timely manner, ensuring system stability and user satisfaction Technical Problem-Solving: Investigate and resolve application and system issues, troubleshoot complex codebases, and implement robust solutions Code Quality & Documentation: Write clean, maintainable code with high test coverage, conduct code reviews, and maintain clear technical and release documentation Continuous Improvement: Continuously look for ways to improve performance, reduce technical debt, and raise the level of automation across our systems and delivery process Required Qualifications Education & Experience: Diploma or Bachelor’s degree in Information Technology, Computer Science, or related field with at least 5 years of hands-on application development experience, including a track record of delivering solutions that improved a business process—not just shipping features Business Acumen & Process Thinking (Core): On top of strong coding skills, a genuine ability to understand how a business operates, ask the right questions of non-technical users, map out a workflow, and spot where it can be automated or improved.

This complements your development work—it does not replace it; you are still expected to build the solution yourself VB.NET Expertise: Strong proficiency in VB.NET and the .NET Framework, including Windows Forms UI design, WCF services, and development Database Skills: Solid experience with MS SQL Server including storedprocedures, SQL query optimisation, database design, and administration Version Control: Proficiency with Bitbucket for version control and collaborativedevelopment Problem-Solving Excellence: Strong analytical and debugging skills with ability to troubleshoot complex codebases independently Self-Driven & Proactive: Ability to work independently with minimal supervision, take ownership of outcomes, and drive improvements without being asked Communication Skills: Excellent written and verbal communication skills in English with ability to engage business users and present ideas clearly to both technical and non-technical audiences AI-Driven Development & Automation (Required): Proficiency with AI-assisted coding tools such as Claude Code, Cursor, or GitHub Copilot is essential—this is a core part of how we build software at Fusang.

Equally important is the judgement to apply AI to the business itself: automating workflows, reducing manual effort, and optimising how work gets done Next.js & React: Experience with Next.js and React is advantageous Domain Knowledge: Knowledge of corporate services, or accounting domains is a plus
