Job description

Why Blueberry?

Every great customer experience is backed by systems that simply work. Trades need to process correctly, reports need to be accurate, and the tools our teams rely on every day need to be fast, reliable, and built to scale. That's where the Operate squad comes in.

Introduction:

Every great customer experience is backed by systems that simply work. Trades need to process correctly, reports need to be accurate, and the tools our teams rely on every day need to be fast, reliable, and built to scale. That's where the Operate squad comes in. As a Senior Software Engineer, you'll build the technology that keeps Blueberry running behind the scenes. From real-time trade processing and operational workflows to internal business platforms and reporting systems, your work will directly support the teams that keep the business moving every day.

This is an end-to-end engineering role for someone who enjoys solving complex backend challenges while still building polished user experiences. You'll own features from database design through APIs, background services, frontend applications, and deployment, collaborating closely with Operations, Finance, Support, and Engineering to deliver software that's reliable, scalable, and built to last. Because in production, "it works on my machine" is less of a victory and more of a warning label.

Note: At Blueberry, moving with purpose means showing up, connecting, and building momentum together. This role is based onsite in Taguig, Monday to Friday, where collaboration happens best.

Description:

We're looking for an experienced Senior Software Engineer to join our Operate squad, where you'll design, build, and maintain the operational systems that power Blueberry's core business. Reporting to the Engineering Manager, you'll develop scalable backend services, modern internal applications, and business-critical platforms that support real-time trade processing, operational workflows, and reporting.

You'll take ownership of solutions from technical design through production, working across C#/.NET, PostgreSQL, React, and modern cloud technologies. If you're passionate about building software that's reliable, maintainable, and engineered for long-term success, we'd love to hear from you.

Backend Engineering & Core Systems

• Design, build, and maintain backend services and APIs supporting real-time trade processing and operational workflows.
• Develop reliable background services and long-running processes that handle high transaction volumes with resilience and accuracy.
• Design and optimise PostgreSQL databases, schema structures, and query performance to ensure data integrity and scalability.
• Build systems that prioritise correctness, reliability, and operational efficiency.

Full Stack Product Development

• Develop and enhance internal business applications and back-office portals using React and TypeScript.
• Deliver end-to-end features spanning database design, backend APIs, background processing, frontend development, and deployment.
• Build reporting capabilities and operational dashboards that provide timely, accurate business insights.
• Continuously improve internal tools that support Operations, Finance, and Support teams.

Operational Excellence

• Investigate and resolve production issues using logs, metrics, traces, and monitoring tools.
• Identify performance bottlenecks and reliability risks before they become business problems.
• Improve observability, monitoring, deployment practices, and platform resilience.
• Help ensure business-critical systems remain stable under production workloads.

Engineering Leadership & Collaboration

• Write clean, maintainable, and thoroughly tested production code.
• Participate in code reviews and contribute to raising engineering standards across the squad.
• Mentor fellow engineers through knowledge sharing and technical guidance.
• Partner closely with Operations, Finance, Product, and Support teams to build practical solutions that solve real business problems.
