Backend/Fullstack Engineer

Job Overview

Givery aims to provide the missing link that our clients need to scout, hire, and train world-class engineers. We are profitable, privately owned, and headquartered in Tokyo, Japan. Our clients include some of the biggest names in Japan. We have a diverse team from all corners of the world, and we are looking for a skilled backend or fullstack engineer to help us expand Track, a platform that helps companies evaluate and train technical engineering skills.

About the Position

In this role, you will be primarily focused on our flagship technical assessment product used by hundreds of enterprise clients across Japan. This means both delivering new product value for our customers and tackling meaningful technical challenges: improving the architecture, reducing tech debt, and making the platform easier to extend and build upon for years to come. Our backend stack includes both TypeScript and Scala — you don't need to know both, but you must be open to working across both day-to-day. You'll be working in a large, mature codebase with real technical debt — we're looking for someone who sees that as a challenge, not a red flag.

Responsibilities

• Take end-to-end ownership of features — from architecture decisions and implementation through testing and deployment. You'll be expected to drive work independently and see it through to production.
• Develop and maintain backend systems across the Assessment Platform Team's product portfolio, working primarily with Scala and TypeScript. While full-stack contributions are welcome, the core focus of this role is backend development.
• Architect and extend features across multiple products, navigating both a large-scale legacy codebase and a modern greenfield service — each with their own technical challenges and opportunities.
• Collaborate with a diverse, distributed engineering team to evaluate and clarify product requirements, and deliver technical solutions that align with user needs.
• Uphold a high-quality code base through automated testing, code reviews, and introducing processes that raise the bar for the whole team — while continuously learning from and mentoring each other.
• Participate actively in sprint ceremonies — planning, retrospectives, and iterative delivery — and contribute to continuous team process improvements.
• Monitor production systems and respond quickly to incidents to ensure stable, reliable operation of our services.

Career path

You have the option to either deepen your expertise as an engineer or lead a team as a manager.

The Attractiveness of the Position

▼ What we're up to
We're the creators of the award winning skill evaluation and training platform 'Track'. We are currently tackling the exciting mission of modernizing Japan's hiring culture and helping companies build and maintain strong engineering teams.

Through this year and beyond we plan to expand our product lineup, enhance our UI/UX, roll out new micro services, and build new features which we hope you'll be a big part in the planning and building.

▼ Awesome tech!
One particular aspect that makes us proud of our team is the fact that we use modern technologies with development practices such as code reviews, continuous integration, unit tests, etc. Engineers feel welcome here.

▼ Work-life balance
We encourage team members to have other activities and responsibilities in life, the average engineer works 40 hours a week. We have flex time, maternity/paternity leave, etc which is something a lot of our proud new parents really appreciate.

▼ Choose where you work (from within Japan)
We are set up for remote work, but you are more than welcome to come to our modern office in Shibuya, Tokyo.

▼ International environment
We have people from all corners of the world working together to build the best products possible. Most Engineers use English day to day, but the perfect candidate will be able to navigate and negotiate our international work environment while making the transition towards an even more global team smooth for the local members too.

We are very proud of what Givery has become. The incredibly low turnover rate of our team proves that Givery fosters a work culture that is both very supportive and welcoming. We are sure, once you meet the team, you will feel it too!
