Apex and multi-tenant platform architecture will be provided for candidates transitioning from traditional

Java/backend backgrounds.)

 API & Middleware Engineering: Develop custom REST/SOAP APIs and Java-based middleware to ensure

secure, bi-directional data synchronisation between Salesforce CRM, client business systems, external

cloud applications and databases, including interface contracts, asynchronous processing, callbacks, retry

and exception handling.

 High-Concurrency Data Pipelines: Design scalable data synchronisation solutions for high-volume

transactions using message queues (e.g., Kafka, RocketMQ) and data integration tools (e.g., Canal, DataX),

including customisation of these tools where required to maintain data consistency across systems.

 Performance Optimisation & Stability: Monitor system performance using logging and diagnostic tools

(e.g., ELK, SkyWalking, Arthas), conduct code reviews, and optimise database queries and caching to

ensure enterprise-grade stability while adhering to Salesforce Governor Limits.

 Technical Leadership: Prepare technical documentation, lead code reviews and post-release reviews, and

share integration and cloud knowledge with the delivery team.

Spring Cloud).

 Database Expertise: Demonstrated hands-on experience designing, scaling and optimising relational and

NoSQL databases (MySQL, Redis, MongoDB, Elasticsearch), including index optimisation, slow-query

analysis, sharding and distributed transactions.

 Integration Tooling: Proven experience designing event-driven architectures, working with enterprise

message brokers and data synchronisation tools, and delivering secure integrations with CRM platforms

and third-party APIs.

 Communication: Good communication and stakeholder management skills, with the ability to explain

technical solutions clearly to both business and engineering audiences. Proficiency in Mandarin to work
