Overview
Product-Focused Backend Engineer – Functional Programming & Distributed Systems
At Ncounter, we’re partnering with a cutting-edge AI company on a mission to redefine how professionals in highly regulated industries interact with complex, multi-modal data. Their platform empowers users to deploy custom no-code AI agents that produce verifiable outputs with full transparency - ensuring trust, compliance, and control remain central to every decision.
As a Backend Engineer, you’ll join a growing team working at the forefront of AI infrastructure. This isn’t just about clean code or strong delivery - it’s about ownership, product intuition, and building for scale. You’ll be part of a lean, high-calibre engineering function where every member contributes to planning, testing, analysis, and execution.
What You’ll Be Doing
- Building and evolving APIs that serve as the backbone for internal systems and customer-facing applications
- Scaling the platform to support heavy, multi-tenant usage patterns and high-throughput AI workloads
- Applying foundation models (GPT-4.1, Claude 4, Gemini 1.5 and successors) to real-world, multi-modal data challenges
- Shipping to production daily in collaboration with Product and Design to solve real user problems
- Playing an active role in shaping team goals, defining technical metrics, and prioritising outcomes over ticket-chasing
Your Background
- Hands-on experience with functional programming (Elixir is a plus, but other languages like Scala, Haskell, Clojure, Go, Node.js, or F# are welcome)
- Proven track record of building and scaling distributed backend systems
- Solid understanding of infrastructure-as-code and cloud orchestration (AWS, Terraform, Docker)
- Familiarity with queue management, observability tooling, and shipping in fast-paced environments
- Awareness of GenAI and prompt engineering, or a keen interest to develop expertise in this area
- A self-starter attitude, with a strong sense of product ownership and a passion for solving end-user challenges
