Senior Fullstack Engineer (Elixir)

• Tellent is a talent management suite: an ATS, an HRIS, and Performance Management, with AI capabilities woven through all of them. Our customers increasingly use more than one product, and expect them to work as one
• The Platform team is where those products meet: shared foundations, cross-module sync, the pieces that make three apps feel like one suite. You’d join Platform and work closely with our Product Enablement team on cross-product work, including a growing set of AI-driven capabilities
• This is a genuinely cross-stack seat. The backend core is Elixir, and Node.js can show up too, for example in Manage. But the problems don’t stay in one codebase: one week it’s a Phoenix service, the next it’s a React screen in one product and an Angular one in another
• We’re looking for someone who follows the problem wherever it lives, doesn’t need a fully specified ticket, and enjoys working in more than one codebase without waiting for a pattern to exist first
• Your 12-Month Journey:
• First 3 months: learn how our products talk to each other, ship your first cross-product improvement in, get comfortable in at least two of our codebases
• Within 6 months: own an enablement or platform area end to end, from an ambiguous ask through design, build, and measured outcome. Be the person others ask about it
• After 1 year: shape how cross-product capabilities get built at Tellent, and be one of the engineers who raises the bar for working across the suite
• Building the shared foundations and integrations that connect our products, on an Elixir/Phoenix core
• Working across the frontend stacks of the products you touch: React in some, Angular in others, whatever the problem needs on top of the backend work. Think 60/40 backend/frontend, not 100/0
• Turning fuzzy enablement and AI ideas into buildable slices: you get problems, not tickets, and help decide what to build before deciding how
• Shipping to mature products with thousands of organizations on them, then checking whether it actually moved anything
• Working in existing codebases with existing conventions. Bringing a new pattern into a mature codebase takes more effort, but we do it often, and your judgment on when it is worth it counts
• Collaboration: daily with the Platform team and Product Enablement (PM, design), plus the engineers of the product teams you integrate with

Benefits

• Hybrid work: You decide if and when you want to come to one of our offices.
• Flexible hours: Our employees can choose which working hours are the best for them
• Training budget: Up to €1500 per year for your personal development. You will keep your skills sharp
• Well-being support: Direct, free, and easy access to professional mental health support (provided by OpenUp)
• Equipment: We offer everyone a MacBook, a screen and Apple accessories
• Fitness subscription: We offer everyone a sports card that is acceptable in many fitness facilities.
• Work from anywhere: Take your laptop and work from anywhere (for up to 4 weeks/year)

• Senior-level judgment: when to refactor, when to ship, when good enough is good enough. Especially: when to follow a product’s existing conventions rather than bring your own
• Comfortable with synchronous collaboration: we balance sync and async work. Expect regular pairing and real-time problem solving alongside independent work
• Real frontend experience in production: React or Angular, ideally exposure to both. This is not a bonus here, it’s part of the job
• Range over depth in any one stack: you’ve worked across several codebases and technologies and are comfortable being the newcomer in one while being the expert in another
• Communication: you can explain trade-offs to product people and hold your own in technical discussions across teams that don’t share a stack. Fluent English
• Product thinking: you ask why before building, push back on requirements that don’t serve the user, prototype cheaply, and are fine being wrong quickly
• Strong backend experience, with Elixir (Phoenix; PostgreSQL, RabbitMQ, Redis, Oban) as a real head start. People join us from other stacks and learn Elixir on the job, so strong fundamentals plus proof you pick up languages fast also works
