Required:

• 3+ in Windows desktop application development using Windows App SDK, WinUI (or similar), C#, XAML — and ideally additional experience with native Windows code (C++, Win32/WinRT/COM).
• Deep understanding of Windows application architecture, including interop between managed code (.NET) and native code.
• Proven track record of designing, building, and shipping production-quality desktop applications, with an emphasis on reliability, performance, scalability, and maintainability.
• Strong experience with accessibility APIs on Windows (e.g. Microsoft UI Automation or similar), and a dedication to building accessible and inclusive software.
• Excellent software engineering fundamentals: OOP, design patterns, data structures, algorithms, memory management, multi-threading or asynchronous programming (where relevant).
• Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions.
• Strong communication skills; ability to articulate tradeoffs, collaborate with cross-functional teams, and drive consensus.
• A user-centric mindset: focus on building polished, intuitive, and accessible experiences for end users.

Preferred / Bonus:

• Experience with writing automated tests for UI — unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks.
• Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load).
• Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions.
• Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications.
• Previous experience in shaping CI/CD workflows, release pipelines, and deployment strategies for desktop applications.
• Demonstrated ability to take ownership of feature areas or modules and drive them long-term, including maintenance, refactoring, and technical debt management.

What we offer

• A high-impact role: you will define architecture, shape the future of our Windows product, and directly influence what millions of users see and experience.
• A collaborative, flat-structure engineering culture — you are not just a coder, but a builder and a decision-maker.
• Opportunities to lead — mentor others, steer technical direction, and grow into broader technical leadership (e.g. Tech Lead, Architect).
• Flexibility, autonomy, and responsibility: you define how to solve problems, own features end-to-end, and contribute to long-term product vision.
• A purpose-driven mission: building software that’s reliable, accessible, and user-centered — making a real difference for people.

The United States Based Salary range for this role is: 140,000-200,000 USD/Year + Bonus + Stock depending on experience

Position Summary

We are looking for a skilled, hands-on senior engineer to build and maintain the core infrastructure and backend services that power our trading platform. You will work on systems where performance, correctness, and uptime are fundamental - not afterthoughts.You write clean, efficient C# and Go, take pride in the quality and reliability of your work, and are comfortable owning complex backend problems from design through production. You have a strong instinct for identifying risk before it becomes an incident, and you bring the kind of engineering discipline that high-stakes, real-time financial systems demand.

Key Responsibilities

• Design, build, and maintain backend services and platform infrastructure in C# and Go, with a focus on performance, reliability, and correctness.
• Own backend components end-to-end - from architecture and implementation through testing, deployment, and on-call support.
• Proactively identify and address technical debt, performance bottlenecks, and reliability risks before they become production incidents.
• Collaborate with the platform tech lead and other engineers on system design, code reviews, and cross-team integration work.
• Contribute to frontend development in React, particularly around platform integrations and internal tooling.
• Write and maintain comprehensive tests, documentation, and runbooks to support operational excellence.
• Participate actively in on-call rotation - owning issues through to resolution and contributing to post-incident reviews.

Qualifications

Required

• Strong C# development skills - solid understanding of the .NET ecosystem, async/await patterns, and performance optimization with modern C# idioms (.NET 6+).
• Hands-on experience building and maintaining backend or platform systems in production environments.
• Experience with low-latency or high-throughput systems, particularly in financial, trading, or data-intensive domains.
• Strong understanding of databases including schema design, query optimization, and transactional integrity (PostgreSQL, MySQL, or similar).
• Experience with RESTful API design, WebSockets, and asynchronous/event-driven architectures.
• Proficiency with CI/CD pipelines, automated testing strategies, and modern DevOps tooling.
• Frontend awareness - comfortable working across the stack, reviewing or contributing to React-based frontend work.
• Reliable and dependable - you follow through, communicate proactively, and treat your commitments seriously.
• Strong communication skills; able to collaborate effectively across engineering and product.

Preferred

• Familiarity with functional programming paradigms - comfortable applying immutability, pure functions, and composition patterns to write more predictable, testable code.
• Proficiency in Go - comfortable writing production-grade services and APIs.
• Experience with React or modern frontend frameworks - able to contribute to platform tooling and interfaces.
• Familiarity with Python for scripting, tooling, or data processing.
• Experience with Kubernetes and container orchestration in production environments.
• Background in trading, futures, prop trading, or fintech - you understand the domain and its performance expectations.
• Familiarity with distributed systems patterns: message queues (Kafka, RabbitMQ), caching strategies (Redis), and service-to-service communication.
• Exposure to observability tooling: Prometheus, Grafana, structured logging, and distributed tracing.
• Experience working in multi-team engineering organizations with shared platform dependencies.

Position Summary

We are looking for a seasoned, hands-on engineer to lead platform and backend engineering on our trading infrastructure.
