AI-Native Fullstack Developer (Python)
Summary
Fullstack developer at Kruko building and maintaining web applications with Python (Django) and modern frontend tech, using Claude Code and AI agents as the core development workflow. Owns features end-to-end — REST APIs, relational databases, Docker, testing — and must work on a Pacific Time schedule from Białystok.
We’re looking for a software engineer who knows how to get things done in an AI-driven development environment.
At Kruko, AI agents are a core part of how we build software. We use Claude Code extensively across development, testing, debugging, code review and everyday engineering workflows.
If you enjoy experimenting with new approaches, building your own workflows and finding smarter ways to deliver reliable software, you’ll fit right in.
Our goal is not to write more code. It’s to deliver better software, faster.
Responsibilities
Design, develop and maintain web applications using Python and modern frontend technologies
Use Claude Code and AI agents as a primary part of your workflow, from understanding requirements to implementation, testing and delivery
Break down complex features into manageable tasks and coordinate AI-assisted workflows to deliver them efficiently
Own features end-to-end: technical decisions, implementation, testing, debugging and production readiness
Design and integrate REST APIs, external services and LLM-powered functionality
Work with relational databases, Docker and existing deployment infrastructure
Investigate problems independently, find root causes and deliver reliable fixes rather than temporary workarounds
Continuously improve your workflows, tools and automation to speed up development without compromising quality
Collaborate with developers, QA and product teams, and proactively flag risks, gaps and opportunities for improvement
Requirements
Practical experience delivering production software using Python and modern backend frameworks. We care about engineering fundamentals, not framework-specific expertise
Hands-on experience with Claude Code or comparable agentic coding tools in real development work
Ability to organise effective AI-assisted workflows: task planning, context management, implementation, testing and verification
Solid understanding of backend architecture, REST APIs and relational databases
Practical experience with Docker, Git and modern development workflows
Familiarity with JavaScript, HTML and CSS (React or Vue is a plus)
Enough engineering knowledge to critically evaluate AI-generated code and spot incorrect assumptions, security, performance and maintainability risks
Strong ownership, independence and initiative: you take responsibility for results and can work through ambiguity
Excellent problem-solving skills, adaptability, curiosity and an efficiency-oriented mindset
Clear communication and the ability to work in an international team
Availability to work on a Pacific Time (PT) schedule
Nice to have:
Experience building custom Claude Code workflows, subagents, skills or development automation
Experience coordinating multiple AI agents or parallel development tasks
Experience with LLM integrations, OpenAI APIs, Twilio or similar services
Knowledge of CI/CD, automated testing and cloud infrastructure
Experience with complex business applications and large existing codebases
We care more about your ability to solve real problems and deliver working software than about years of experience or a long list of technologies.
We offer
Competitive compensation based on experience and skills
B2B contract or employment contract
Flexible working hours
An international team working on challenging software projects
The opportunity to shape and improve AI-native software development workflows
