Job description

Role Overview

We’re seeking full-stack developers with strong business analysis skills to join our Liquid Decisions consulting team. You’ll work directly with clients to configure, develop, and deploy solutions — building front-ends, reporting tools, and advanced analytics workflows on our DuckDB-based platform.

You’ll need to be an expert user of GPTs for software engineering, applying them across the entire development lifecycle — from requirements gathering to architecture, coding, testing, and deployment.

This is a hands-on, client-facing role: you’ll be the technical problem solver in the room, translating business goals into robust, testable, scalable solutions — while maintaining top-tier professional standards.

Your Responsibilities

• Engage directly with clients to gather requirements, clarify goals, and define success metrics.
• Configure and customize Liquid Decisions solutions for specific business needs.
• Using our platform technologies, we design and deliver full-stack features — frontend UI, backend services, and database logic.
• Build and integrate reporting tools and visual analytics.
• Develop SQL-based workflows in DuckDB, including ingestion, transformation, and visualization.
• Build integrations using Python, JavaScript/TypeScript, and GPT-based development workflows.
• Apply rigorous testing practices to ensure correctness, reliability, and maintainability.
• Diagnose and resolve complex technical issues across the stack.
• Work collaboratively with stakeholders to optimize workflows, data structures, and application performance.

Required Skills & Experience

• Consultant mindset — professional, self-motivated, comfortable in client-facing engagements.
• Excellent English — spoken, written, and thinking in English with technical clarity.
• Expert GPT usage — proven ability to leverage GPTs for architecture, coding, debugging, testing, and documentation.
• Exceptional troubleshooting and testing ability.
• Computer Science degree (or equivalent experience) with strong coding skills in at least two languages, including Python.
• Intermediate PostgreSQL skills and familiarity with relational + columnar systems.
• Proven frontend development skills in modern frameworks (Svelte, React, or similar).
• SQL proficiency (DuckDB and Postgres preferred).
• Experience with data pipelines (REST/WebSocket APIs, Streams, Queues).
• Backend development in Python and frontend in JavaScript/TypeScript.
• Familiarity with REST/GraphQL APIs and cloud-native environments.
• DevOps & CI/CD — comfortable setting up build pipelines, automated testing, and deployment workflows.
• Infrastructure self-sufficiency — able to provision, configure, and maintain local and cloud environments without hand-holding.
• Security and access control — understanding of authentication, authorization, role-based access control (RBAC), and secure coding practices.

Nice to Have

• Experience with Kubernetes or containerized deployments.
• Experience with data lakes, analytic DAGs, or columnar databases.
• Familiarity with Svelte or other modern frontend frameworks.

What We Offer

• High-impact consulting experience on cutting-edge SQL-native platforms.
• Direct influence on high-performance, auditable, versioned data systems.
• Work alongside senior DuckDB engineers and platform architects.
• Continuous learning from experts in data engineering, full-stack development, and AI-assisted software delivery.
