• Core backend services: campaign orchestrators, FSM-based workflow engines, API integrations with telephony (Twilio), voice AI platforms, insurance carriers, and CRMs. • System design and architecture decisions alongside the CTO. • Multi-server deployments, async processing pipelines, event-driven flows. • Frontend integration via Next.js (familiarity needed, not the focus).

Role Description We need a senior .NET/C# engineer who has operated real production systems under load — not just built them. Someone who thinks in architecture first, can design for resilience and scale, and knows what it means to keep a highly integrated backend alive across many moving parts. - Core backend services: campaign orchestrators, FSM-based workflow engines, API integrations with telephony (Twilio), voice AI platforms, insurance carriers, and CRMs. - System design and architecture decisions alongside the CTO. - Multi-server deployments, async processing pipelines, event-driven flows. - Frontend integration via Next.js (familiarity needed, not the focus). - Deep .NET / C# expertise. - Strong CS fundamentals: OOP, SOLID, SOA, design patterns. - Experience designing and operating event-driven backend architectures. - Experience running systems on multi-server infrastructure with real traffic — you know what horizontal scaling, fail over, and stateless design actually mean in practice. - Proficiency with parallel and concurrent programming — async/await, thread safety, queues, etc. - Experience integrating many external services/APIs in a single backend — you've dealt with the chaos and know how to tame it. - Ability to design backend architecture from scratch for complex web applications. - Fluent in AI dev tools: Claude Code, Cursor, GitHub Copilot — part of your daily workflow, not occasional use. - Communicates clearly in English; Spanish is a plus. Qualifications - Voice AI / telephony integrations (Twilio, Retell, ElevenLabs, Deepgram). - AWS, Vercel, or Railway deployments. - Startup experience — comfortable with shifting requirements. Benefits - Compensation in USD. - Fully remote work. - High-growth opportunities in an international company.
