As a Senior .NET Engineer, you will play a key role in designing, developing, and maintaining robust backend systems and APIs that power our core products. You’ll collaborate closely with frontend engineers, product managers, and QA teams to ensure seamless data flow, system reliability, and efficient service integration. Your contributions will include optimizing performance, enhancing system architecture, and applying best practices in software development, security, and deployment to support rapid and reliable product delivery. Our Engineering Team The CMG engineering team consists of domain experts who work collaboratively within a culture of cross-domain knowledge sharing. We value engineers who are passionate about modern technologies and best practices. Our engineers are encouraged to challenge the status quo and are constantly seeking improvement and efficiency in our code-base and platform. CMG engineers are empowered to explore solutions using leading edge technologies such as AI and bring recommendations to the table. We are in a period of making impactful engineering decisions. As part of our process, we believe in taking the time for research and prototyping - this is critical in making the right decisions. Given the experience of our team, we have naturally adopted best practices from local development, through code review and into production rollouts. Besides the standard pull requests, test automation, code coverage tracking, containerization, and one-click deployments, we are constantly reviewing these foundational components to develop new best practices. ## Responsibilities - Operate as a product engineer focused on solving real user and business problems, not clearing a backlog. You bring ideas, challenge assumptions, and own outcomes. - Work in an AI-first development flow. Use Claude not just to go faster, but to do more: explore multiple approaches, validate ideas quickly, and build things that previously wouldn't have been worth the effort. - Primarily focused on backend: designing, developing, and maintaining scalable services with .NET 10, and GraphQL. Comfortable stepping into front-end work when the problem calls for it. - You're aligned to a product team and typically work alongside one or two other engineers on any given project, pairing on tough problems, reviewing each other's work, and shipping together rather than in parallel. - Uphold a high-quality bar. Engineers write their own tests at the unit, integration, and end-to-end levels, and every line of code, human-written or AI-assisted, is reviewed by a human before it ships. - Drive technical improvements across the codebase. Proactively identify friction, propose changes, and see them through to adoption. - Serve as the first DataLab hire in Czechia, working from our Brno office. Shift your schedule to US Pacific morning hours (until ~20:00 CET) 2-3 days per week to collaborate with the rest of the team, which aligns to US time zones, attend project meetings, and to provide support. - Support the product you build by participating in the team’s on-call rotation and responding to production incidents. ## Qualifications - Must be based in the Czech Republic. - C#, ASP.NET Core: 3+ years. - Software Engineering: 5+ Years. - English level - C1 or C2. - Fintech experience is a plus. - Experience developing AI-powered applications is a plus. Our Tech Stack - Latest .NET version for our backend services. - Federated GraphQL .NET server running in Hot Chocolate. - MassTransit and RabbitMQ for messaging. - Hangfire for our background processing. - Redis Cache for distributed caching and real-time messaging. - Azure as infrastructure provider. - Docker + Kubernetes for microservice orchestration using Istio service mesh. - PostgreSQL for relational db, ElasticSearch for indexing, Redis for caching. - DataDog and OpenTelemetry for observability. - GitHub for our Version Control and CI (with our own runners). - React with TypeScript on our front-end. ## Our Values - We innovate with purpose - We focus on outcomes vs. output - We believe diverse and inclusive teams fuel innovation - We are humble yet candid - We do right by the customer ## What we offer - Unlimited vacation - Meal vouchers paid in full by the company - Multisport card contribution - Pension contributions - Language courses - Centrally located office in the heart of Brno - Bi-weekly team lunches provided by the company - Tech courses and conferences - Top of the line MacBook - Company team building events - Flexible working hours and the possibility to work from home CMG embraces our ongoing commitment to building a culture reflecting the people, perspectives, and passions it represents. We will accept nothing less than equity, inclusion, and belonging for all. With the only constant in life being change, we will always listen, learn, and improve for the betterment of our teams, customers, and communities. CMG is proud to be an Equal Opportunity Employer. ## About Capital Markets Gateway ## Company Overview - **One-liner**: Capital Markets Gateway (CMG) provides workflow management and data intelligence solutions that connect buy-side and sell-side participants throughout the entire equity capital markets (ECM) offering process. - **Entity Type**: Private (latest Series C raised $30M in April 2025) - **Headquarters**: New York, New York, United States - **Founded**: 2015 - **Founders**: Greg Ingram (CEO & Co-Founder), Mike Wilcox (President, COO & Co-Founder) ## Core Business - **Primary industry**: Financial Services – Equity Capital Markets (ECM) technology and data - **Target customers**: B2B – Investment banks (sell side) and asset managers, hedge funds, long-only mutual funds (buy side) - **Mission or purpose statement**: To transform the equity capital markets by digitizing workflows, delivering real-time data intelligence, and enabling faster, better-informed decisions for ECM participants. ## Products & Services - **CMG DataLab™**: A real-time ECM market data and analytics platform covering IPOs, follow-ons, ABBs, blocks, rights offerings, converts, ATMs, PIPEs, and registered directs across 50+ regions, with 20+ years of historical data, 550+ data fields, and 100+ filters.
