Let's start with the role
You will join an autonomous Agile team and work closely with the Product Owner, Agile Delivery Lead, Automation Testers, and other Software Engineers to create a competitive advantage for Kaizen and offer a unique online experience to our customers. Besides being part of the Agile team, you will work closely with talented backend professionals within the Backend Chapter. 🙌
Senior Software engineers in Kaizen are responsible for a multitude of projects, from our customer-facing websites and mobile applications to our admin and internal tools and backend services, most of them withstanding high volume / traffic.

MS SQL Server is used for most of our storage needs, but also Redis and ElasticSearch are used when it makes sense to do so. RabbitMQ is our go-to message broker.

Your Team:
The Engineering Excellence Team is for engineers who build the systems that power everything else. No product tickets. No UI tweaks. No support loops. You’ll create the tools, standards, and frameworks that make every development team faster and stronger.
This is deep technical work with massive impact - shaping architecture, unifying processes, and defining how engineering is done across the company. A place for senior engineers who want to build the backbone, not the features.
This is not a product team. It’s a technical excellence engine for people who want to build the systems behind the systems - and elevate the whole company through world‑class engineering.
How You’ll Make an Impact:
- Design and build scalable frontend frameworks, libraries, and tooling that serve as the foundation for all product teams.
- Define and drive frontend architecture standards across the organization, ensuring consistency, performance, and maintainability at scale.
- Create reusable component systems and design system integrations that enable teams to build high-quality UIs faster.
- Develop and maintain shared tooling (e.g. build systems, CLI tools, templates) that streamline development workflows and improve developer experience.
- Establish best practices for code quality, testing, accessibility, and performance across all frontend codebases.
- Partner with engineering teams to identify gaps, remove friction, and enable faster, more reliable frontend development.
- Drive initiatives to modernize frontend stacks, improve performance, and unify technologies across teams.
- Act as a technical leader through code reviews, architecture discussions, and hands-on guidance, raising the bar for frontend engineering across the company.
- Continuously evaluate and introduce new tools and approaches that improve scalability, maintainability, and developer productivity.
Who You Are:
- 4+ years of professional Front-End Development experience
- 3+ years working with React, Vue, or Angular
- Strong knowledge of JavaScript, HTML, and SCSS
- Solid understanding of core coding principles and architectural best practices
- A habit of writing clean, well-structured, maintainable code
- Experience with unit testing is a strong plus
- Proactive, self-motivated, and driven to contribute beyond your tasks
- Comfortable communicating in English in a fast-paced, global environment
What We Offer:
We’re not just about work, we are about creating a great place to grow, connect, and enjoy the journey. Here’s what you can expect when you join us:
- Competitive Salary Package: We value your skills, dedication, and contributions
- Time Off: Enjoy 21+ days of annual paid leave so you can rest, recharge, and come back inspired
- Bonus & Rewards: Performance-based annual bonuses, special vouchers for birthdays and welcoming a newborn
- Health & Wellness: Additional Health insurance including dental care; Co-funding a Multisport/Coolfit card to help you stay active
- Extra Benefits: Employee discounts at various retailers and a monthly allowance for public transportation
- Great Office Locations: Central office location in Sofia and Plovdiv
- Relax & Recharge Zone: Take a break with colleagues in our PlayStation and Pool Area - perfect for recharging during the day
Wait, there’s more:
- Happy Hour Fridays: Every Friday we host themed Happy Hours with snacks, fun activities, and plenty of opportunities to connect and unwind with colleagues
- Multicultural Days: Celebrate diversity and experience the traditions, food, and cultures of teammates from around the world
- Massages at the Office: Weekly Free Recreational Massages to help relax during the workday
- Chess Lessons: Sharpen your strategic thinking and enjoy some friendly competition with colleagues

Your Team:
The Product Launch team is built for people who don’t just maintain systems but create them. We take products from zero to hero, and scale them until they’re strong enough to be handed over to core teams. No legacy constraints. No endless support cycles. Just greenfield builds, modern tech, and real ownership from day one.
We move fast, think lean, and execute with focus, one product at a time, full commitment, full impact. Every sprint matter, every decision ship value. This is not a support team. It’s a build-from-scratch engine for products that matter, because every hero needs a superhero.
How You’ll Make an Impact:
- Build front-end applications from the ground up - turning early-stage product ideas into scalable, production-ready user experiences.
- Own the frontend architecture of new products, making key decisions around frameworks, structure, and performance from day one.
- Develop fast, responsive, and high-quality user interfaces using modern technologies, with a strong focus on usability and real-world impact.
- Collaborate closely with product, design, and backend teams to shape features early, not just implement them.
- Establish and drive best practices for code quality, testing, and maintainability across greenfield projects.
- Move quickly from concept to release - shipping iteratively, validating ideas, and continuously improving based on feedback.
- Identify and solve problems proactively, balancing speed with long-term scalability as products evolve.
- Contribute to a culture of ownership, where every decision directly influences the success of the product from day one.
