About The Position

Enterprise AI is moving from pilots to production, and the constraint is no longer the model — it's the data. Agents are only as good as what they can sense, trust, and act on in the moment, and real-time, event-driven data is becoming the foundation every serious AI system runs on. Solace is the leading platform for the enterprise AI era. Established enterprises worldwide — including RBC Capital Markets, Bosch, Heineken, PSA Singapore, United Airlines, Schwarz Group, and hundreds more — have built their business around Solace to enable intelligent, real-time experiences, modernize their application and integration landscape, and create seamless digital journeys for their customers, partners, and employees. So, the next time you drive a car, order furniture online, fly in a plane, check your bank balance on your phone, your positive experience could be a direct result of our technology—and your hard work! We at Solace believe we build the world's best event broker - the backbone of real-time business, trusted to move billions of messages a day across cloud, on-premises, and edge environments with unmatched reliability and performance. At the heart of the Solace Event Broker lies the datapath - the engine responsible for moving messages at high rate, with low latency and utmost reliability. The Dataplane Adapters team owns the protocol surface: the MQTT, AMQP, REST, RDP, and Kafka adapters that let clients and applications connect, publish, and consume messages. This work spans our custom hardware appliance - built around FPGAs and a Cavium network processor - and our software broker running on Intel server processors. The code is highly multi-threaded and performance-oriented, and our developers regularly go deep into TCP, hardware interfaces, and OS internals to deliver features that meet our strict performance and reliability bar. We are looking for energetic developers that relish the challenge of building complicated features with C++ in this multi-threaded environment. Candidates should enjoy going deep to learn about messaging protocol internals, TCP and OS networking behaviour, and the details of the Linux kernel.
