Job summary

TechInsights in Warsaw seeks an experienced Software Developer to join the Circuit Analysis Tools team. You will transform complex customer problems into reliable software, collaborating with product, engineering, and domain experts to deliver testable features.

You will lead by example, applying Clean Architecture and Domain-Driven Design while emphasizing automated testing, maintainability, and AI-assisted development. You’ll mentor peers and own code in production.

Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, or a related field.
• Significant hands-on experience building and maintaining production software systems.
• Strong grasp of software architecture, design principles, APIs, data and distributed systems.
• Proven ability to design maintainable systems using Clean Architecture and Domain‑Driven Design principles.
• Hands-on experience with automated testing strategy. TDD, BDD and specification by example are highly desirable.
• Experience with CI/CD, cloud infrastructure, observability and running production software.
• Strong critical thinking, with the ability to spot underlying problems and weigh trade-offs.
• Curiosity about customers and the business domain, not only the technology.
• A bias toward action, experimentation and incremental delivery.
• Track record of coaching, mentoring and technical leadership.
• A continuous-improvement mindset, and comfort questioning established practices while staying open to being wrong.
• Strong communication and collaboration skills with both technical and non-technical colleagues.

Responsibilities

• Learn our customers, their workflows and the circuit analysis domain. Work with Product and domain experts to turn customer needs into clear, testable features.
• Question requirements and look for the real customer need. Choose the simplest solution that works, and check after release that it delivered the intended result.
• Design well-structured, maintainable software. Apply Clean Architecture, separation of concerns and Domain‑Driven Design where they make sense.
• Design APIs, components and data models that are easy to understand, test and change. Improve technical debt step by step as systems grow.
• Build effective automated test strategies across unit, component, contract, integration and end‑to‑end testing. Use TDD and BDD where they help.
• Own your software in production. That includes monitoring, fixing defects, investigating incidents and learning from how the system behaves in production.
• Use CI/CD and Infrastructure as Code so deployments and recoveries are repeatable and safe.
• Prefer small batches and short feedback loops. Find and remove friction, rework and recurring defects in how the team delivers software.
• Prototype quickly to reduce uncertainty. Bring successful experiments up to production standards.
• Coach and mentor engineers through code reviews, pair programming and design discussions. Encourage open, constructive technical debate.
• Use AI tools across design, coding, testing, debugging and refactoring. Review AI‑generated work critically before accepting it.
