You'll design and operate the backend services, APIs, data pipelines, and storage systems that make trusted organizational and user context available to agents and product experiences with the appropriate latency, quality, security, and cost. Select storage and retrieval patterns across operational databases, data warehouses and lakes, search systems, caches, and graph or vector technologies based on access patterns.

Our founders, Shachar (ex-Palo Alto Networks, AWS, Demisto) and Dan (ex-Abnormal Security, Twitter) have previously built, launched, and scaled cybersecurity products loved and trusted by tens of thousands of customers, and have the customer, technology, and security know-hows to deliver this vision. You'll design and operate the systems that keep our ingestion pipelines, data stores, and AI workloads running reliably at scale — and you'll do it in an environment where the infrastructure decisions you make have a direct impact on how fast security teams can detect and respond to threats.

FULL_TIME

For example, within the U.S., this range aligns with typical salaries for similar roles in major markets such as New York or Seattle (generally $140,000–$150,000) and mid-cost regions such as Dallas or Charlotte (typically $120,000–$130,000). You enjoy building systems from scratch, can navigate policy ambiguity with confidence, and are motivated by the potential to create tools that help communities and governments replicate successful climate solutions while optimizing renewable energy deployment.

How do you enforce access controls across complex entity relationships, ensure privacy and audit-ability, and let users self-service team permissions, all while guaranteeing excellent performance for checks that are performed on literally every request?. The TPA industry is a $500bn sleeper industry that has historically been seen as a services business, bogged down by manual processes and legacy systems (for context, our team couldn’t even access these on our Macs).

This is a deeply technical role with real scope: you'll architect and ship systems that power AI-driven financial analysis, build the tooling and infrastructure that domain experts rely on, and set the engineering bar for how we build AI systems responsibly in a regulated industry. Deep curiosity about where AI-native software is heading — you actively explore emerging capabilities and are excited to help define how they should be applied in real production systems, not just follow established patterns.

To conform to U.S. Government export regulations applicable to that information, applicant must either be (A) a U.S. person, defined as a (i) U.S. citizen or national, (ii) U.S. lawful permanent resident (green card holder), (iii) refugee under 8 U.S.C. § 1157, or (iv) asylee under 8 U.S.C. § 1158, (B) eligible to access the export controlled information without a required export authorization, or (C) eligible and reasonably likely to obtain the required export authorization from the applicable U.S. government agency. Day-to-day, you''ll develop GPU-aware sandboxing and scheduling strategies, optimize containerization and I/O performance for latency-sensitive workloads, and influence architectural decisions across Linux internals, container runtimes, virtualization layers, and GPU drivers.

CoreWeave Inc

Senior Software Engineer II

You’ll be learning side by side with founding engineers who previously built at Uber, Datadog, Ramp, and Tennr — and who are now applying that experience to one of the most important problems in healthcare. Home care providers today are drowning in chaos - spreadsheets, late-night calls, missed visits, caregivers churning at 80% a year.

Project Method

Junior Engineer @ Zingage

Our roots remain deeply embedded in AI research, and we’ve brought together researchers from institutions including MIT, Harvard, Berkeley, Columbia, and Cornell with world-class technical staff and operators from companies like Google, Meta, Datadog, ServiceNow, and Citadel Securities to take on one of the hardest problems for AI to solve. That means working end-to-end on the harness and context engineering that shape agent reasoning, the streaming and orchestration layers that put it in front of engineers mid-incident, and the observability and evaluation systems that tell us whether any of it is actually working.

AI Engineer - Product Engineer

This is real information retrieval and applied ML work on production infrastructure — search systems, embedding-based retrieval, learning-to-rank, LLM-powered contextual and conversational search, image embeddings for photo-based search — not configuring a hosted search widget or calling a model API and moving on. Build and operate real search infrastructure — Elasticsearch/OpenSearch, Vespa, or vector-search databases like pgvector, Pinecone, or Weaviate — to power ranking and multi-modal search across our marketplace.

Recruiting From Scratch

Senior AI/ML Software Engineer

A strong, defensible point of view on what makes a great design system, backed by experience driving adoption across a product organization: not just building it, but getting designers and engineers to actually use it. Define the AI enablement strategy for design-to-engineering: determine how AI tools are integrated into the workflow from prototype to production, and build the systems that make the whole team faster and higher-quality.

Our roots remain deeply embedded in AI research, and we’ve brought together researchers from institutions including MIT, Harvard, Berkeley, Columbia, and Cornell with world-class technical staff and operators from companies like Google, Meta, Datadog, ServiceNow, and Citadel Securities to take on one of the hardest problems for AI to solve. Our agents autonomously diagnose and resolve production incidents for some of the world's largest enterprises, and improving them is an experimental problem: form a hypothesis about agent behavior, test it against real incident data, and ship what works.
