RemotePeople; Województwo małopolskie; On-site; PLN 180,000 - 260,000; Full time

Job summary

RemotePeople in Krakow or Sofia is seeking a Senior Software Engineer to join our Platform Engineering team. You will build internal developer tooling, including CLI apps for environment setup, CI/CD modernization, and data access libraries that accelerate how engineers ship software.

You will own tools end-to-end from design to adoption, mentor junior engineers, and drive DevOps and telemetry across the SDLC. Strong Python, cloud, and CI/CD experience are required.

Qualifications

• 4-8 years of professional software engineering experience building production systems at scale.
• Bachelor's degree or higher in Computer Science, Engineering, or a related field.
• Deep proficiency in Python - OOP, design patterns, packaging, dependency management, and building maintainable libraries and CLI tools.
• Demonstrated ability to design well-structured, loosely coupled systems and make trade-offs between simplicity, extensibility, and performance.
• Hands-on experience with cloud platforms (Azure, AWS, or GCP).
• Experience with Docker, Kubernetes, and CI/CD pipelines (GitHub Actions, Jenkins, or similar); exposure to GitOps (Flux, ArgoCD) is a plus.
• Experience with relational databases (PostgreSQL, MSSQL) and NoSQL/key-value stores, with the ability to design clean data access abstractions.

Responsibilities

• Architect and deliver internal tools and libraries that are well-defined, modular, secure, scalable, and actively maintained.
• Contribute across the full development lifecycle — architecture, prototyping, testing, development, and support.
• Drive modern engineering practices through code and design reviews; champion DevOps principles and high-quality telemetry.
• Evaluate emerging technologies through proof-of-concept work and recommend adoption where they fit.
• Lead design discussions and align teams on architectural decisions for shared platform components.
• Mentor junior engineers through coaching, pairing, and code/design reviews.
• Proficient integrating AI coding assistants, CLIs, and MCPs into daily development workflows.
• Uses AI effectively across the SDLC — planning, design, implementation, debugging, deployment, and observability.
• Builds reusable AI tooling (agent rules, skills, internal MCPs) that compounds team productivity, with sound judgment on when AI is (and isn’t) the right tool.
• Balances AI-driven velocity with engineering rigor — automated testing, structural guardrails, and CI checks to validate AI-generated code.
