Stigg The Usage Runtime for AI Products But what is it exactly? Built by former New Relic engineers, Stigg provides the infrastructure AI companies need to meter, monetize, and govern product usage at scale. Our real-time usage runtime enables companies to manage entitlements, usage metering, credits, budgets, and access controls - all without building complex infrastructure from scratch. So what? Why now? AI is fundamentally changing how software is consumed and monetized. Every API request, inference, or agent action can generate real cost, while traditional billing systems only report usage after it happens. Stigg helps AI companies make real-time decisions about what each customer, user, team, or agent is allowed to do - before the cost is incurred. This gives engineering teams the control they need, while allowing Product and GTM teams to quickly introduce and evolve new monetization models. Are you funded? 💰 We are!

Join Ovalix and Help Secure the AI Era We're building the platform that gives enterprises visibility, governance, and protection across their AI ecosystem, from public GenAI tools and homegrown apps to coding assistants and autonomous AI agents. We're looking for people who want to solve real enterprise AI security challenges and move fast with a friendly, focused team. Responsibilities Own our backend end-to-end — from architecture to production — on a Python, AWS, and Kubernetes stack that secures how organizations use AI. Small senior team, real ownership, fast shipping. Requirements 5+ years of backend development experience, with strong Python. Proven experience designing, building, and operating production services and APIs — databases, cloud (preferably AWS), Docker/Kubernetes. Ownership-driven and comfortable with the pace and ambiguity of a startup.

Description We’re building a new kind of observability platform — one that developers actually want to use. groundcover is a fast-growing B2D company set to reinvent the way developers monitor their cloud-native applications and impact their organization’s scale. We help teams by providing them with the insights they need to troubleshoot better and faster when trouble hits. We believe that even the most complex systems can have a flawless and amazing user journey. At groundcover, we care deeply about performance, clarity, and building tools that feel right. We’re a small team of engineers who enjoy solving hard backend problems and working close to the data. If you're into Go, value clean architecture, and love building for other developers — this might be a great fit. What You’ll Do • Build high-performance backend systems in Go • Work on real-time data pipelines and large-scale telemetry infrastructure • Tackle tough challenges in distributed systems, scale, and performance • Collaborate with infrastructure, frontend, and product teams to ship features end to end Requirements Requirements: • Have 6+ years of backend development experience, especially with Go • Have built or worked on high-throughput, low-latency systems • Understand cloud-native environments (Kubernetes, containers, etc.) • Care about clean, maintainable, well-architected code • Love working on developer-first products and want your work to have real impact Why groundcover: • We’re developers building for developers. • You’ll have real ownership over your work. • We care about the craft, not just the speed. • Hybrid work, Tel Aviv-based, flexible and focused.

We're reimagining enterprise Identity and Access Management from the ground up. Founded by serial entrepreneurs Shai Morag and Tal Marom and backed by a $60M seed round from Greylock, Accel, and CRV, we're building the next generation of identity security. Identity is the gateway to everything- who's let in, who's kept out, and it's now the number one attack vector in the enterprise. The tools built to govern it were designed for a slower world of human users and static environments. That world is gone. Identities are exploding across human, machine, and AI agents faster than legacy systems can track, and security teams are left patching together five disconnected tools that still can't answer "who has access to what, right now." We think the answer isn't another point solution- it's a new foundation. Oak is the AI-native Identity Operating System: an AI connector framework that reaches any application, a live identity graph built from raw evidence, and a team of AI agents that governs the full lifecycle of every identity in one platform. We're building Oak's AI-native core from day one-engineered for what enterprise identity is becoming, not patched onto what it used to be. And we're just getting started. About the Role: We're looking for an experienced Backend Engineer to join a highly skilled R&D team of exceptional peers. You are a builder at heart - someone who deeply understands distributed systems and takes pride in shipping efficient, resilient code. We need an engineer who instinctively drives projects forward, stepping in smoothly whether it’s designing greenfield architecture or tackling complex engineering problem. If you are passionate about your craft, naturally curious about modern engineering paradigms, and prioritize collective success, we want you on our team. What You'll Do • Drive the end-to-end development of critical backend components - from research and system design to deployment, observability, and long-term maintenance. • Serve as a trusted voice in technological and architectural decisions, balancing rapid execution with pragmatic, scalable system design. • Architect and facilitate full agentic workflows, integrating AI capabilities directly into our core platform. • Act as an autonomous executor who seamlessly collaborates with the broader team, elevating engineering standards and delivering top-tier value to our customers. What You'll Bring • 8+ years of backend engineering in high-level programming languages (e.g., Go, Python), with a proven track record of solving hard technical problems. • A low-ego, high-impact approach: You are self-directed, driven by delivery, and willing to roll up your sleeves for the foundational work that ensures system stability. • Deep architectural pragmatism: Extensive experience with microservices, databases, and asynchronous systems, coupled with a nuanced understanding of exactly when and how to deploy them. • Forward-thinking adaptability: A continuous desire to explore new technologies, leveraging modern development tools and AI paradigms to accelerate your workflows and multiply your impact. • Bachelor of Science in Computer Science, Software Engineering, or equivalent battle-tested experience.
