Junior Software Engineer

About LemonEdge

Private markets run on numbers that have to be right. Yet much of the industry still relies on spreadsheets and manual processes to manage increasingly complex financial operations.

LemonEdge is building the next generation of accounting technology to change that. Our platform helps fund administrators and asset managers automate complexity, improve accuracy, and scale with confidence.

The engineering challenge is significant: building software that makes complex financial processes simpler, more reliable, and more transparent. Every calculation matter, and every feature needs to stand up to real-world scrutiny.

What We're Looking for

We’re looking for a Junior Software Engineer ready to take ownership of meaningful work, from the first conversation in refinement through development, testing, and production.

At LemonEdge, you won’t just be picking up tasks and passing them along. You’ll own your stories end to end, make thoughtful engineering decisions, and grow toward taking responsibility for an entire component.

This is a full-stack engineering role with a strong backend focus: approximately 75% server-side development in C# / .NET and 25% frontend across our WPF desktop application and React web application.

What You'll Do

• Own your work end to end. Take stories from refinement through design, development, testing, and production deployment. Follow through to make sure your changes work as expected in a live environment.
• Build for accuracy. Validate outputs against expected results, investigate discrepancies, and test edge cases rather than relying solely on happy-path scenarios.
• Make thoughtful engineering decisions. Work within our existing architecture and modules, write maintainable code, and understand and communicate the trade-offs behind your approach.
• Use AI thoughtfully. Leverage AI-assisted development tools where they add value, while applying appropriate scrutiny, testing, and verification based on the risk and complexity of each change.
• Take responsibility for what you ship. Participate in a light on-call rotation, using established runbooks and working alongside experienced engineers when issues need escalation.
• Bring clarity to complexity. Ask questions, engage the right stakeholders, and turn ambiguous requirements into well-defined, actionable work.

What You'll Bring

• Professional experience developing and shipping software, with evidence that you can take work from start to finish with limited supervision.
• Proficiency in at least one statically typed programming language, such as C#, Java, Go, or TypeScript. Our primary technology stack is C# / .NET.
• Solid SQL skills, including working with relational data models, writing queries, and understanding query execution plans.
• A strong testing mindset, with an appreciation for edge cases, validation, and the importance of verifying AI-generated code.
• An understanding of secure development fundamentals, including input validation and protecting sensitive information in code, logs, and application workflows.
• A structured approach to debugging: forming hypotheses, using debuggers and logs to investigate issues, and understanding why problems occur rather than simply fixing symptoms.
• Clear, proactive communication skills, including writing useful pull request descriptions, responding constructively to feedback, and raising blockers early.

Bonus Points If You Bring

• Professional experience with C# / .NET.
• Experience integrating with external services, including appropriate use of timeouts, retries, and idempotency.
• Experience writing reversible database migrations and validating them against realistic data.
• Familiarity with cloud-hosted SaaS applications, CI/CD pipelines, or containerized environments.
• Exposure to finance, accounting, or another domain where accuracy, consistency, and reconciliation are critical.
• Frontend development experience, particularly with WPF or React.
• Hands-on experience with agentic AI workflows or building AI-powered capabilities into a product.
