We’re building Wall Street’s next-generation stocks trading platform — and we’re hiring C# engineers!
 

We’re Pinnakl, a SaaS company that’s been quietly disrupting the hedge fund software space for the past 8 years. Today, 100+ Wall Street clients run on our platform — and we’re just getting started. We’re expanding our engineering team and looking for exceptional engineers (5+ years experience) who write clean, elegant, and performant code. You’ll work on real-time trading systems used by some of the most sophisticated funds in the world. If you love beautiful architecture, complex challenges, and real product impact, this is one of those rare chances to build something that actually moves markets.
 

You’ll build and maintain backend services powering a large, data-heavy enterprise platform. This is a hands-on role: schema design, API endpoints, performance/security hardening, and production support—shipping features end-to-end with a small, high-ownership team.
 

What kind of Features you will work on
 

1. Implementation of personalized news notifications feature Develop a highly effective subscription management mechanism enabling customers to receive timely updates about significant corporate actions/events affecting assets in their investment portfolios. Ensure stable connectivity with data providers, reliable storage solutions, and reusable access to collected data for other Pinnakl microservices.

2. Performance optimization of stock trading services
Conduct thorough profiling and monitoring analysis to identify bottlenecks and critical areas. Apply advanced techniques including caching mechanisms, responsibility redistribution among microservices, and refactoring current code base. Implement automated testing practices along with CI/CD methodologies.

3. Enhancing system observability across all infrastructure components
Investigate the full lifecycle of customer requests and integrate modern tools to improve observability. Enhance logging systems, robust tracing capabilities, and comprehensive monitoring frameworks. Create user-friendly dashboards providing instant visibility into problem zones and facilitating quick issue resolution.

4. Integration of AI technologies for risk calculation and compliance control
Design and build infrastructure for seamless interaction with machine learning models aimed at improving risk calculations of investment portfolios and trading compliance control.

5. Modernization of CRM system using microservice architecture

Migrate the existing CRM solution onto a new microservices architecture based on Clean Architecture principles. This effort will accelerate our company's large-scale transformation program of IT infrastructure.

 

Responsibilities

• Scoping, architecting, modeling and implementing multiple new product features as you collaborating with front end engineers, UX designers, and founder.
• Getting your hands dirty, writing API endpoints, schemas, data-handling functions, and other code.
• Advising and guiding the evolution of our product roadmap, providing feedback on feasibility and estimated timelines for new feature development.
• Optimize applications for performance, accessibility, and security

Required Experience

• Strong backend experience in C# / .NET
• Strong experience in ASP.NET Core
• Experience with unit testing in .NET
• Experience in SQL
• Knowledge of SOLID principles
• Experience in microservice architecture
• Nice to have (But not required)
  • Knowledge of Clean Architecture principles
  • Experience in buses (like Kafka and Azure Service Bus) and caches (like Redis)

Expectations

We're building mission-critical software for some of the most demanding clients in finance. Here's what that means in practice:

• Ownership over tickets: You'll work within structured sprints, but we expect you to think critically, ask clarifying questions, and take ownership of outcomes — not just check off tasks.
• Delivery-focused culture: We measure success by shipped features and real product impact, not story points or hours logged.
• Full-time commitment: This is a dedicated role requiring 45–50 hours per week. We don't have rigid hours, but expect most work to wrap up by 7 PM your local time. We're looking for engineers who are fully invested in Pinnakl's success — this isn't compatible with side-freelancing.
• AI-assisted development is expected.

If you're looking for a place where you can grow, ship meaningful work, and be treated as a core part of the team — not just a ticket processor — we'd love to hear from you.

Why Pinnakl

• You’ll work with a strong group of senior engineers and learn fast by shipping.
• You’ll build real production systems used daily (not VC-funded MVP work).
• Your work has direct impact on how Wall Street operates, replacing legacy systems that haven’t evolved in decades.
• As the company grows, compensation grows with it.
• We invest in long-term team members and aim to provide stability in a market that’s changing quickly.
