##### About the Opportunity

Our client is a leading European online car marketplace, serving 30M+ monthly users across 18 countries.

As a Senior/Lead FullStack Engineer:

- You will play a key technical leadership role within the client’s engineering organization. You will design, build, and evolve scalable backend services and user-facing features across our product suite.

- You will contribute across a polyglot stack that includes PHP (Laravel), JavaScript, and TypeScript, collaborating closely with product managers, designers, and other engineers to deliver robust, maintainable, and secure solutions.

- This role requires a high level of proficiency in using AI tools in day-to-day software development. AI-assisted workflows are not optional—they are an expected part of how we design, implement, test, debug, document, and optimize software. As a Senior/ Lead engineer, you will also help elevate your team’s AI capabilities by modeling effective usage patterns and sharing best practices.

##### What You'll Do

- Architect, design, and implement scalable services and product features using PHP (Laravel)

- Use AI tools extensively for code generation, refactoring, test creation, debugging, performance optimization, and documentation

- Critically evaluate AI-generated outputs to ensure correctness, security, maintainability, and alignment with architectural standards

- Lead technical design discussions and contribute to system and API architecture decisions

- Own complex features end-to-end, from technical design through deployment, monitoring, and iteration

- Drive improvements in code quality, performance, reliability, and security

- Write clean, maintainable, and well-tested code with strong automated test coverage

- Conduct in-depth code reviews and mentor engineers through actionable feedback

- Coach teammates on effective and responsible AI usage in software engineering workflows

- Collaborate cross-functionally to translate business requirements into scalable technical solutions

- Contribute to cloud infrastructure and services (AWS), ensuring high availability and operational excellence

- Participate in compensated on-call rotations to ensure platform reliability

- Champion DevOps best practices, CI/CD improvements, and observability standards

- Identify and lead technical initiatives that improve long-term platform sustainability

##### What We're Looking For

- 6-8 years of extensive professional experience in backend software development

- Strong expertise in PHP and Laravel (6+ years)

- Proficiency in JavaScript and TypeScript for modern frontend development

- Demonstrated advanced proficiency using AI tools in day-to-day engineering work (code generation, debugging, test automation, documentation, architectural exploration)

- Strong ability to validate, refine, and productionize AI-assisted outputs

- Experience improving team-level engineering practices

- Deep understanding of API design, distributed systems, and scalable architecture patterns

- Experience working with AWS or similar cloud environments

- Strong knowledge of CI/CD pipelines and modern DevOps practices

- Experience designing and optimizing relational databases and data models

- Proven ability to independently lead complex technical initiatives

- Strong problem-solving skills and ability to navigate ambiguity

- Clear and effective communication skills

- Participate in compensated on-call rotations to ensure reliability of our backend services

- Canadian timezone working hours

- English proficiency at B2/C1 level or higher.

**Nice to Have**

- Experience integrating AI capabilities into production products (e.g., LLM integrations, AI-driven features, intelligent workflows)

- Experience designing AI-enabled user experiences or backend AI services

- Experience in automotive, dealer software, or SaaS platforms

- Experience with containerization (Docker, Kubernetes)

- Event-driven architectures and messaging systems

- Performance tuning and high-scale system optimization

- Experience working in multi-product platform environments
**We offer*:**

- Flexible working format - remote, office-based or flexible

- A competitive salary and good compensation package

- Personalized career growth

- Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)

- Active tech communities with regular knowledge sharing

- Education reimbursement

- Memorable anniversary presents

- Corporate events and team buildings

- Other location-specific benefits
