CostCare AI is a Ukrainian B2B SaaS startup building AI Sales Agents for the Social Commerce market. Our agents act as virtual employees — answering customer inquiries, syncing with CRMs, booking consultations, and even generating payment links — all within social media platforms.
We’ve recently raised $500,000 in funding and are working closely with early users to improve the product and find the right market focus. The roadmap ahead is exciting and we’re scaling fast.
Your role:
We’re looking for a strong Middle Python Engineer who enjoys building fast, iterating quickly, and cares about clean, reliable code. You’ll join at a stage where your voice matters — working on architecture, improving performance, and shaping how our AI agents function and scale. What you’ll be working on: * Build backend features for voice & chat LLM agents * Build multi-agent flows: prompting, tool calling, handoffs * Improve existing agentic systems : reliability, latency, and overall quality * Help define and build our eval system (quality/latency/accuracy) * Work on integrations such as: telegram, whatsapp, CRMs(hubspot, etc) * Collaborate directly with CTO
The product is still in an early stage, so you’ll have the opportunity to influence the tech stack and help shape the architecture as we grow. We’re looking for someone who: * Has deep Python experience and strong backend engineering fundamentals. * Understands system design, the pros and cons of different approaches, and can deliver from idea to production. * Communicates clearly and takes ownership. * Has a product mindset — solves real problems, not just code tickets. * Can work independently and isn’t afraid to ask questions, make decisions, or challenge ideas.
Nice to have: * Experience working with AI agents / LLMs * Prompt engineering skills * Familiarity with LangGraph or vector databases
Our Values: * Mutual Respect: We’re building a healthy, collaborative environment where people feel safe, supported, and inspired to grow together. * Customer Obsession: We believe our unfair advantage is truly caring about our customers and solving their real problems. * Trust & Responsibility: We trust each other to take ownership, and in return, we expect them to be responsible and keep growing. * Honesty: Mistakes happen — what matters is having the courage to own them, learn from them, and solve things together. * Ambition: We’re aiming high — to build a billion-dollar company and lead the way in AI agent technology.
Why join us? * You’ll join early, shape core systems, and make a real impact. * Zero bureaucracy, flexible hours, fully remote. * Paid time off (20 vacation + 10 sick days). * Transparent, respectful, and feedback-driven team. * We’re ambitious but grounded — aiming to build something useful and lasting.
Let’s talk if this sounds interesting — we’d love to hear from you!
