In the past 18 years, Mito has grown from 3 guys, averaging an age of 27, to over 230 people dreaming up the most clever things our clients have ever seen (unless they’ve seen the Large Hadron Collider). We create campaigns, websites, apps and other digital solutions for inspiring brands all over the world.
At our Technology department, we are super proud of the complex digital solutions we build for telcos, lottery companies and aviation brands all over the world. Right now, we’re looking for a seasoned Node.js pro to grab the wheel and take the lead on mission-critical, customer-facing applications: someone who speaks Fastify fluently, thrives on designing and scaling high-load API gateways, and knows exactly how to keep production from crashing into an infinite loop.
Requirements
Your tasks will be:
- Developing high-quality software to achieve goals in a fast-paced business environment.
- Using Node.js and Fastify to deliver core functionality, designing and maintaining high-load API gateways.
- Mentoring developers and fostering a culture of technical excellence within your team.
- Syncing regularly with business stakeholders to seamlessly align technical architecture with business objectives (translating developer wizardry into real-world business talk).
- Taking part in incident resolution and problem management.
- Participating in technical design and change management.
- Contributing to architectural and design decisions.
- Estimating development and delivery times based on documented requirements, specifications, and technical designs (crystal balls are welcome, but realistic timelines work even better).
- Writing unit and integration tests, participating in end-to-end test development.
- Working together with our in-house DevOps team to streamline and sustain a well-functioning CI/CD pipeline.
- Ensuring PCI/DSS compliance for the code you deliver with your team.
- Discussing technical solutions with other developers
- Participating in your peers’ code reviews. Don’t worry, if you do it well, they’re going to love you for it.
We need you to have:
- At least 6+ years of experience with Node.js.
- Deep knowledge of Fastify, microservices and enterprise-grade large-scale applications.
- Hands-on experience designing and managing high-load API gateways (Kong is highly preferred, but AWS API Gateway is great too).
- Experience with optimizing high-load, distributed server-side services.
- Experience deploying, operating, and scaling applications within the AWS ecosystem.
- A steady hand with version control in GitHub and containerization using Docker.
- A security-focused mindset and experience with secure coding standards.
- A solid understanding of state-of-the-art buzzwords: business logic, data access layers, SOA concepts, microservices architecture, OOP, JSON, you name it.
- A decent level of English. This is an international community where documentation and formal communication are in English (if something’s wrong, you can curse in Hungarian, that sounds way better).
We will be super happy if you:
- Have familiarity with the .NET ecosystem and can comfortably read and understand C# code.
- Have hands-on experience with PCI/DSS or you already have an OWASP certification.
- Are familiar with the Agile methodology and SAFe principles.
