Senior Software Engineer – Reconciliation & Data Platform
We are looking for a Software Engineer to join our Reconciliation team. You will design and build high-throughput reconciliation systems that ensure the accuracy and consistency of financial data across trading, settlement, and fee/commission pipelines. The role sits at the intersection of backend engineering and data development — you need to be equally comfortable writing production Java services and wrangling large-scale data with Flink and Hive.
Responsibilities
- Design and implement reconciliation frameworks to detect discrepancies across financial systems (trading, settlement, commission, etc.)
- Build and maintain real-time and batch data pipelines using Apache Flink and Hive
- Write complex SQL for data validation, anomaly detection, and root-cause analysis
- Collaborate with Finance, Risk, and Product teams to define reconciliation rules and SLAs
- Optimize system performance and reliability for high-volume, low-latency reconciliation scenarios
- Leverage AI/LLM tooling to accelerate development, automate anomaly triage, and improve operational efficiency
Requirements
- 3+ years of backend development experience, primarily in Java
- Strong SQL skills — able to write and optimize complex queries for large datasets
- Hands-on experience with big data frameworks: Apache Flink (streaming) and Hive (batch/warehouse)
- Data-sensitive mindset: comfortable reasoning about data accuracy, consistency, and edge cases
- Experience in financial reconciliation, settlement systems, or data quality engineering is a strong plus
- Familiarity with AI tools (Copilot, LLM-based automation, etc.) and ability to apply them in daily engineering work is a plus
Nice to have
- Experience with data warehousing concepts (partitioning, slowly changing dimensions, data lineage)
- Familiarity with Kafka, Spark, or similar data infrastructure
- Background in crypto, fintech, or high-frequency trading environments
What does a Java developer in web3 do?
A Java developer in web3 would likely be focused on developing applications that use the Java programming language in the context of the web3 technology stack
Web3 is a collective term used to refer to the next generation of decentralized, blockchain-based technologies that are aimed at creating a more open and secure internet
In this context, a Java developer would be responsible for writing code that interacts with web3 technologies, such as decentralized applications (DApps) and smart contracts, to create new tools and services that run on the blockchain
This could involve working with cutting-edge technologies such as Ethereum, which is a popular blockchain platform that uses the Java programming language, as well as other web3 technologies and frameworks.
