Software Development: Design, build, and optimize high-quality software using modern engineering principles and practices.
Automated Testing: Lead by example in writing and maintaining automated unit, integration, and end-to-end tests to ensure stability and reliability.
SDLC & Scrum Practices: Actively contribute to and help facilitate the running of our Software Development Life Cycle (SDLC) and Scrum process, including workshops, sprint planning, backlog refinement, daily standups, sprint reviews, and retrospectives.
Architecture & Design: Pro-actively engage in discussions and decisions around system architecture, scalability, and maintainability.
Collaboration: Partner with product managers, designers, and stakeholders to define requirements, refine scope, and deliver impactful solutions.
Code Quality & Best Practices: Enforce and improve development standards, ensuring code consistency, maintainability, and adherence to best practices.
Continuous Improvement: Champion process and tooling improvements across the engineering organization.
Documentation: Ensure technical and architectural documentation is complete, clear, and up-to-date.

Required skills and qualifications:

Experience: Minimum 5+ years of professional software development experience, with proven ability to deliver complex applications in production environments.

Back end skills:

Strong proficiency in C#, Python, and/or Java.
Deep experience building and maintaining APIs and integrations using RESTful architectures.

Proficiency with automated testing frameworks (xUnit, NUnit, JUnit, PyTest).
Solid experience with CI/CD pipelines, Git, and modern DevOps practices.

Front end skills:

Proficiency in JavaScript and TypeScript.
Strong experience with React and/or Angular frameworks.
Deep understanding of HTML5, CSS3, and responsive UI/UX principles.
Proven ability to integrate front-end applications with back-end RESTful services and APIs.
Experience with front-end testing tools such as Testcafe, Playright or Cypress.
Comfort with modern build tools and workflows (Webpack, npm, etc.).

Leadership and soft skills:

Proven experience mentoring and supporting junior team members.
Strong analytical, architectural, and problem-solving abilities.
Excellent communication skills — able to explain complex technical concepts clearly.
High sense of ownership and accountability for deliverables.
Collaborative and proactive approach to teamwork and stakeholder engagement.
Commitment to quality, performance, and maintainability.

Preferred qualifications:

Experience with cloud platforms (AWS, Azure, or GCP).
Familiarity with containerization (Docker, Kubernetes) and modern deployment automation.
Experience implementing Agile/Scrum best practices in development teams.
Understanding of security, scalability, and performance optimization in distributed systems.
