About the role Workera is an AI-native company transforming how enterprises measure and develop talent in the age of AI. We are looking for people who thrive in a fast-moving, AI-first environment — where experimentation, continuous learning, and intelligent automation are part of how we operate every day. Whether building product, driving revenue, or enabling operations, your work directly advances our mission to empower individuals and organizations to thrive by understanding, measuring, and improving their skills — across any skill — at any time.
What You'll Do Within 3 months, you will
Develop a strong understanding of Workera's AI-powered platform, customers, and business model
Be fully up to speed with our development process and using AI tools and agentic coding workflows to learn about and contribute to the codebase
Deliver a project in a small team that touches every relevant part of the codebase, and be ready to troubleshoot production issues throughout the stack
Within 6 months, you will
Lead a full project, owning scoring, architecture, build, and rollout end-to-end
Identify opportunities to use AI tools and automation to increase leverage and impact in your team
Deeply understand our market position and communicate clearly in cross-functional discussions
Within 9 months, you will
Identify and contribute to cross-team technical initiatives that boost up our AI-first engineering organization
Architect and own backend systems that are robust, performant, and built to scale with a growing customer base
Confidently managing risks and uncertainties while building and shipping AI-powered product areas
What You'll Bring
7+ years of software engineering experience with a strong backend specialization, in a SaaS or startup environment — full-stack capability is valued, but your heart is in the backend
Practical experience building scalable backend systems top to bottom — ideally in Elixir/Phoenix/PostgreSQL; Go, Erlang, or Clojure backgrounds also considered; a proven ability to learn new technologies quickly is a must if you don't have Elixir experience
Day-to-day use of AI tools to enhance personal productivity (e.g., Claude Code or equivalent); bonus for experience building user-facing GenAI features
Deep expertise delivering platform-critical, high-stakes backend projects where robustness, performance, and troubleshooting are non-negotiable
Strong user and customer orientation — you understand and optimize user flows, not just code
Willingness and ability to contribute on the frontend when needed (Phoenix + React)
2+ years working with a fully remote, async team
Comfort working in an AI-first environment where intelligent automation and experimentation are part of daily operations with demonstrated ability to leverage AI tools (e.g., Claude, ChatGPT, or equivalent) to improve productivity, insight generation, or decision-making
Strong systems thinking — ability to see how your backend work connects to a broader AI-driven platform and enterprise customers
Excellent written and verbal communication skills in English
You should be located in the UK, Ireland, or the Netherlands. You are free to choose working hours that suit you best, as long as there is an overlap with your team for most of the day.
Our stack primarily consists of Elixir + PostgreSQL on the backend and Phoenix on the frontend (with some pockets of React). We monitor performance using Sentry, and our platform is hosted on AWS, running on Docker containers defined in Terraform. Our platform is AI-native, and we make extensive use of LLMs in our application. Our code lives on GitHub - in fact, GitHub, Slack and Linear is where most of the collaboration happens (almost no emails get sent around). We practice using Loom to demo our work. That's the gist of it - we can dive into other technologies used when we get to know each other.
About Workera Workera is a fast-growing, Series B Silicon Valley company redefining how enterprises understand, develop, and mobilize talent.
