Senior Front-End Software Engineer

We are the tech company behind the media and sporting moments that matter.

Over four decades, Deltatre has grown to employ more than 1,000 experts worldwide.

We're trusted by the biggest broadcasters, telcos, media companies, sport governing bodies, leagues, and federations.

Our products, innovation, dependability, and people continue to redefine how the value of live and on-demand sport, film, TV, and news content is maximized across streaming, digital, data, graphics, officiating, and through marketplace strategy and growth services.

Position:

This role sits within Deltatre's Engineering & Technology function, spanning both our DIGITAL Solutions and OTT Solutions platforms — the systems powering content management, personalization, and real-time data alongside live and on-demand streaming experiences for some of the world's most recognised media brands. You will work across web and mobile applications, contributing to the component systems, performance standards, and delivery pipelines that underpin our clients' products.

We are hiring for two tracks. Both roles are hands-on engineering positions for people who care about quality, take ownership of their work, and are comfortable in a cross-functional environment. The distinction lies in depth of experience, scope of contribution, and degree of independence expected.

For this role you must be able to work on a hybrid basis with at least 1 day per week working in our office based in Skopje.

Responsibilities

As a Senior Front-End Engineer, you will take end-to-end ownership of features and solutions across our platform. Beyond your own delivery, you will contribute actively to how the team works — mentoring less experienced developers, shaping technical decisions at the solution and feature level, and helping establish standards that others build on.

Your day-to-day will include:

• Design, build, and maintain high-quality front-end experiences across web and mobile platforms
• Take the lead on solution and feature design — bringing well-reasoned technical proposals and seeing them through to delivery
• Mentor mid-level and junior developers through code review, pairing, and day-to-day guidance — helping build capability across the team
• Contribute to and evolve our shared component library and design system, with a focus on consistency, accessibility, and long-term maintainability
• Set a high bar for front-end performance — profiling, measuring, and improving rendering, load times, and analytics instrumentation
• Collaborate with back-end engineers, QA, and product to define robust, scalable solutions
• Contribute to CI/CD pipelines and front-end tooling, improving build reliability and developer experience
• Stay current with the front-end ecosystem and bring emerging patterns and practice into the team

Requirements:

You produce work that others learn from. You don't wait to be asked — you identify problems, propose solutions, and follow through. You understand that technical quality and team capability are inseparable, and you invest in both.

We are hiring for two tracks. The requirements below differ slightly depending on which platform you'd be joining — read both and apply to the one that fits your background.

• Experience building and maintainingcomponent libraries or design systems
• Deep understanding of front-end performance — measurement, optimisation, and analytics integration
• Experience with RESTful APIs or GraphQL
• Comfortable working within CI/CD pipelines and modern front-end tooling
• Demonstrated testing approach — experience with modern front-end testing frameworks and a test-first mindset
• Clear communicator who can articulate technical decisions to peers and cross-functional stakeholders

Valued

• Experience in the streaming or media industry — VOD, live events, player integrations, or DRM
• Hands-on 10-foot development experience across Samsung Tizen, LG webOS, Apple TV, or Android TV / Fire TV
• Familiarity with client-side data event instrumentation
• Knowledge of Node.js, AWS (Lambda, S3, CloudFront), or back-end concepts

DIGITAL Solutions Role

Who Thrives Here

We look for people who bring rigour and curiosity to their work in equal measure. You take quality seriously — not as a constraint, but as a standard you set for yourself. You communicate clearly, flag issues early, and treat your colleagues' time and context with respect. You are honest about what you know and what you are still learning.

This is an environment that rewards initiative. If you are looking for genuinely interesting work on a technically demanding platform, alongside people who hold themselves to a high standard, this may be exactly right.

Not sure which level is right for you? Apply anyway and tell us where you think you sit. We'll figure it out together.

Process and what to expect

Assessment stages

• Introductory conversation: this is a step for us to get to know each other better, and for us to answer all questions you might have around Deltatre.
• Codility Assessment: a structured, self-paced coding assessment to give you a sense of what you'll be dealing with. This step is the entry point in our process and is required to access the following steps.
• 1-hour Technical round of Interview: we will use your assessment as a starting point for a discussion with senior team members. You will walk through your code and discuss additional technical aspects in detail. This conversation, combined with the output of the assessment, allows us to make a solid technical evaluation.
• 1-hour Competency Based Interview: we are going to ask you some situational questions around how you deal with real-life scenarios at work. Easier doing it than explaining it!

If any of these formats would be difficult for you, tell us — we adjust regularly and can usually accommodate.

Accessibility and accommodation questions are welcome at any stage, including before you apply. Tell us what would work for you.
