To keep pace with our expanding global trading operations, we are seeking a C++ Market Data Engineer to design and build ultra-low-latency feed handlers for premier vendor feeds and major exchange multicast feeds. This is a high-impact role that sits at the heart of Trexquant's trading platform; the quality, speed, and reliability of your code directly influence every strategy we run. Responsibilities Design & implement high-performance feed handlers in modern C++ for equities, futures, and options across global venues (e.g., NYSE, CME, Refinitiv RTS, Bloomberg B-PIPE). Optimize for micro- and nanosecond latency using lock-free data structures, cache-friendly memory layouts, and kernel-bypass networking where appropriate. Build reusable libraries for message decoding, normalization, and publication to internal buses shared by research, simulation, and live trading systems. Collaborate with cross-functional teams to tune TCP/UDP multicast stacks, kernel parameters, and NIC settings for deterministic performance. Provide robust failover, gap-recovery, and replay mechanisms to guarantee data integrity under packet loss or venue outages. Instrument code paths with precision timestamping and performance metrics; drive continuous latency regression testing and capacity planning. Partner closely with quantitative researchers to understand downstream data requirements and to fine-tune delivery formats for both simulation and live trading. Produce clear architecture documents, operational run-books, and post-mortems; participate in a 24×7 follow-the-sun support rotation for mission-critical market-data services. Requirements BS/MS/PhD in Computer Science, Electrical Engineering, or related field. 3+ years of professional C++ (14,17,20) development experience focused on low-latency, high-throughput systems. Proven track record building or maintaining real-time market-data feeds (e.g., Refinitiv RTS/TREP, Bloomberg B-PIPE, OPRA, CME MDP, ITCH). Strong grasp of concurrency, lock-free algorithms, memory-model semantics, and compiler optimizations. Familiarity with serialization formats (FAST, SBE, Protocol Buffers) and time-series databases or in-memory caches. Comfort with scripting in Python for prototyping, testing, and ops automation. Excellent problem-solving skills, ownership mindset, and ability to thrive in a fast-paced trading environment. Familiarity with containerization (Docker/K8s) and public-cloud networking (AWS, GCP). Benefits Competitive salary, plus bonus based on individual and company performance. Collaborative, casual, and friendly work environment while solving the hardest problems in the financial markets.

As a Senior Python Developer, you will work with our application and collaborate with third-party teams to integrate our application with theirs. Our backend is a set of APIs consumed by various frontend React applications, including online ordering websites, mobile apps, and in-store ordering kiosks. We have three main APIs, each quite large: Admin API (for the admin panel), Order API (for e-commerce products), and In-store API (for our in-store products, including kiosks and kitchen display systems). The main application is based on Flask and uses MySQL for its database. We do not use an ORM to talk to the database, so you must be well-versed in writing SQL and working directly with a database to be effective. Integrating with APIs provided by the backend team to provide seamless connections between our applications. Integrating with external APIs directly. Expanding the capabilities of our REST APIs: building new endpoints using the OpenAPI specification. Building new backend functionalities to help expand the feature set of our customer-facing products. Improving the end-user experience by reducing the latency of API endpoints using all tools available (SQL queries, indices, caching, background tasks, Datadog APM, etc.). Tracking down and fixing bugs encountered by end users. Refactoring parts of the application that require modernization. Expanding the scope and coverage of the automated test suite. Requirements Powerful written and verbal communication skills. 5-10 years as a Python Developer. Experience with Flask or Django, with a strong preference for Flask experience. A thorough understanding of working directly with databases and writing custom SQL queries. Experience working on a consumer-facing application with high-performance requirements. Experience integrating with external APIs for payments and other non-core features. Experience working on an e-commerce application, preferably in the restaurant or retail industry. Knowledge of and experience with CRM and/or loyalty & marketing applications, directly or indirectly by integrating with such systems. Hands-on experience with Celery, Redis, Docker, Linux, and AWS is a plus. Experience working with an established code base and taking ownership of certain parts of the code base (if you have only worked on projects built from scratch, this role is not for you). Ability to work independently with minimal supervision: You should be a self-starter who doesn’t require constant oversight to stay on task and enjoys solving problems primarily on your own.
