• Design and prototype integrations between partner products and the Nebius platform — fast, hands-on, and technically sound. • Define reference architectures for partner integrations — not just what works, but how it should work at scale and in production. • Scope partner architectures against our platform — how does this product actually work on our stack, where does it snap together, where does it break. • Build production-quality proof-of-concepts across the AI stack including agentic pipelines, RAG architectures, inference optimization patterns, and multi-model orchestration. • Produce working proof-of-concepts that serve as the starting point for product creation — not a requirements doc, a working thing. • Maintain a library of reference architectures and integration patterns that internal product and engineering teams can build from. • Work directly with partner engineering teams to scope, prototype, and progress integrations. • Assess partner architectures honestly — if the integration is painful, that is signal; if it snaps together in a weekend, that is also signal; report both. • Provide technical guidance to partners on how to maximize performance, reliability, and cost efficiency on Nebius infrastructure. • Produce technical scoping that gives your pod partner and internal teams a clear picture of integration feasibility, depth, and complexity. • Translate external integration findings into actionable product requirements for Nebius platform teams. • Work with ISV partners, SI teams, and field teams to scale solution adoption and drive revenue once a solution is ready. • Surface recurring architectural patterns and integration gaps to inform platform roadmap decisions. • Participate in platform planning as the technical voice of what you are seeing and building in the field. • Represent Nebius at hackathons, in open source communities, and at technical events. • Build in public — demos, reference architectures, and integrations that establish Nebius as the platform serious AI builders choose. • Stay current with the AI tooling ecosystem — you know what shipped last week and what it means for our stack.

Full TimeRemoteTeam 201-500

Role Description We're hiring a Senior Automation Engineer to start by automating Cordatus's own operations, then move into client engagements as we scale our automation practice. You'll have unusually broad scope: choose the tools, design the solution, build it, ship it, and own the outcome. You'll work directly with the founder, an automation engineer turned operator, and play a real role in shaping how we deliver automation as a service. What You'll Do - Build production-grade automations across business functions (finance ops, RevOps, HR, IT and security workflows) - Pick the right tool for the job. RPA where it fits, AI agents where they're better, custom code when neither does - Document thoroughly and build for handoff. We're a managed services firm, durability matters - Lead client-facing automation projects as we scale the practice - Mentor junior engineers as the team grows Qualifications - 6 to 8 years building production automation in a business context, not just side projects - Deep experience in at least one major RPA platform (UiPath, Power Automate, or Blue Prism) - Strong Python and/or JavaScript. You can write actual code, not just configure low-code tools - Hands-on experience with LLM-based automation (n8n, Make, custom agent frameworks, or similar) - Comfortable integrating systems via APIs (REST, webhooks, OAuth) - Security-aware. You understand why credentials, data handling, and access controls matter, especially in regulated environments - Strong async communicator with reliable overlap to US business hours - Comfortable being client-facing (you'll get there as the practice scales) Nice to Have - Familiarity with broader iPaaS tools (Workato, Zapier, n8n, Make) - ISO 27001 or SOC 2 awareness - Prior consulting or managed services experience - Experience with PE-backed or mid-market environments - ClickUp, HubSpot, or similar workflow and CRM platforms (we use these internally) Benefits - Fully remote - Real ownership and influence on what gets built and how - Direct work with the founder, not buried under layers - A clear path to lead our automation practice as we grow it How to Apply Send a resume and a short note about a recent automation you're proud of. What was the problem, what did you build, what was the outcome? Bonus points if you include something you learned the hard way.
