Principal EngineerNew York City or remote (US/EU time zones) Engineering full timeAlgoX2 is building a next-generation data-streaming platform for AI workloads. The system is multi-core, single-threaded, and built on formal code generation (see openacr.org).
Experience with OpenACR is not required—only a commitment to writing software with uncompromising reliability.Language and ApproachWe use a small, strictly defined subset of C++, closer to a safer C. Object-oriented constructs are avoided entirely. All programs are written as real-time in-memory databases, emphasizing determinism, predictability, and verifiable behavior.About the PlatformAlgoX2 unifies stream processing, connectors, and lakehouse gateways into one fault-tolerant cluster running on commodity hardware. It delivers 10× higher throughput and up to 90% lower total cost than legacy stacks, with microsecond latency and full Kafka compatibility. It also supports Redis, NATS, and MQTT.The RoleAs a Principal Engineer and early team member, you will help design and implement the system core, working directly with PCI, NVME, InfiniBand, and formal code generators.
The role values correctness and conceptual clarity over speed or volume.ResponsibilitiesDesign and build core platform components in a formally specified environmentEnsure reliability, determinism, and performance across all subsystemsCollaborate with founders on technical direction and design philosophyRequirementsStrong background in C++ or low-level systems programmingUnderstanding of computational complexity and how computers actually execute codePreference for correctness and simplicity over optimizationAbility to work within a minimal, disciplined language subsetNice to HaveFamiliarity with Kafka, Pulsar, or traditional RDBMS systemsExperience with large-scale, high-throughput, or real-time environmentsCompensationCompetitive salary with meaningful equityClear path toward senior or leadership rolesEmail your resume and a short note to No forms, results matter.
