Job Description
Sowelo Consulting sp. z o.o. is assisting in the search for a Full Stack Engineer for a fully remote position based in Europe. The hiring client develops AI-native productivity applications aimed at the general public, focusing on email, calendars, notes, and task management. This core engineering role involves building proactive, AI-driven tools that integrate long-term memory, LLM orchestration, and low-latency streaming without requiring users to master complex prompts.
The position is ideal for an engineer who wants to construct production-grade AI systems and agentic workflows from scratch within a small, high-talent-density team. The successful candidate will own the product layer that turns intelligent agent capabilities into reliable, user-facing workflows. Sowelo Consulting confirms that its candidate selection process relies entirely on human judgment without automated screening algorithms.
Responsibilities
- Build end-to-end product features covering the frontend, backend, and AI integrations.
- Design multi-step agent workflows that manage planning, tool use, failure, and recovery across sessions.
- Integrate LLMs, memory architectures, and external APIs into systems that remain reliable under real-world conditions.
- Architect user experience patterns for real-time interactions, incorporating streaming states, partial results, and latency constraints.
- Enhance system reliability, observability, monitoring, and fallback mechanisms for LLM and tool failures.
- Gather user signals and telemetry to support ongoing model evaluation, hallucination reduction, and product iteration.
- Collaborate with machine learning and backend engineering teams to define system architectures and establish scalable integration patterns.
Requirements
- Strong professional full-stack development experience utilizing modern frameworks such as Next.js, Python, and Node.js.
- Practical background in constructing AI-driven applications, RAG systems, or working directly with LLM APIs including OpenAI, Anthropic, or open-source models.
- Solid understanding of system design, API architecture, and SQL and NoSQL database systems.
- Demonstrated capability to design robust user experiences around network latency, graceful degradation, and non-deterministic model responses.
- Experience with containerization, deployment pipelines, and cloud orchestration tools like Docker and Kubernetes.
- Capacity to manage ambiguity, exercise independent judgment, and take features from concept to production with high ownership.
- Strong product intuition centered on client-side reliability and proactive, user-centric UX.
Core Skills
Benefits
- Participation in a small, high-talent-density team building a greenfield AI productivity product from scratch.
- Collaboration with high-caliber engineers from top tech companies.
- Fully remote, global team environment with strong ownership and high-impact visibility.
- Significant equity and compensation flexibility.
