[Hiring] Senior Software Engineer @Zylun Philippines, Inc.

Role Description

This is a fully remote role on PH night shift schedule (9 PM–6 AM) with work equipment provided.

We are looking for one senior engineer or above for a financial systems project focused on ledger, reconciliation, and banking platform integrations. The engineer must understand the financial consequences of design decisions and build systems that preserve accurate, auditable records under retries, concurrency, and partial failures.

The role requires .NET/C#, PostgreSQL, Azure, AI-enabled delivery using Claude Code, and hands-on AI/LLM or generative AI implementation experience. Ideally, candidates will bring 3–5 years or more of experience building financial applications.

Qualifications

• At least 5 years of overall professional working experience.
• Senior-level or higher engineering capability, with independent ownership of complex backend systems; ideally 3–5 years or more building financial applications.
• C# and .NET backend development.
• Practical experience with ledger or reconciliation solutions and banking or financial platform integrations, including transaction lifecycles and discrepancy resolution.
• Deep understanding of immutability, idempotency, race conditions, auditability, and financial transaction consistency. Ability to prevent decimal precision loss and rounding errors.
• Strong PostgreSQL skills covering schema design, SQL, transactions, isolation levels, locking, constraints, indexing, performance, and exact numeric data types.
• Hands-on Azure experience developing, deploying, and supporting services, with secure configuration, access controls, monitoring, and production troubleshooting.
• Experience delivering backend applications within a Microsoft technology environment.
• Demonstrated AI-enabled delivery using coding assistants, with the ability to use Claude Code effectively and independently review, debug, and test generated code.
• Hands-on implementation of AI/LLM or generative AI application features beyond coding-assistant usage, including API integration, output evaluation, failure handling, and data protection.
• Strong testing skills covering monetary calculations, duplicate processing, concurrent transactions, reconciliation, integration failures, and recovery.
• Clear written and spoken communication; ability to clarify financial requirements, document decisions, and communicate progress and blockers.

Requirements

• Technology Stack: C#, .NET.
• Database: PostgreSQL — required.
• Cloud: Microsoft Azure or AWS — required.
• Financial systems: Ledger, reconciliation, banking integrations.
• AI implementations: AI/LLM and generative AI — required.
• Development tooling: Claude Code; AI-enabled delivery — required.
