We are looking for a senior frontend engineer to help build a modern web platform for technical and data-intensive workflows.

You will work on complex interfaces involving search, metadata, permissions, configuration, long-running processes, and interactive data exploration. The role is a good fit for someone who enjoys turning technically sophisticated systems into clear, reliable user experiences.

What you will do

• Build and maintain the application using React and TypeScript.
• Develop search, filtering, catalogue, and detailed data views.
• Create interfaces for users, organisations, permissions, and secure sharing.
• Build configuration workflows for technical and machine-learning use cases.
• Develop dashboards for usage, processing status, and system activity.
• Integrate OAuth/OIDC-based authentication and access control.
• Design interfaces for asynchronous and long-running backend operations.
• Establish reusable components, testing practices, and frontend architecture.
• Collaborate closely with backend engineers, product, and design.

What we are looking for

• Strong production experience with React and TypeScript.
• Experience building complex, data-intensive web applications.
• Strong knowledge of state management, asynchronous workflows, and API integration.
• Experience with search, filtering, tables, forms, and permission-management interfaces.
• Ability to simplify complex technical concepts through thoughtful product design.
• Familiarity with frontend testing and performance optimisation.
• Experience integrating REST APIs, OAuth, OIDC, or role-based access control.
• Strong attention to usability, interaction quality, and visual detail.

Nice to have

• Experience with Next.js, TanStack Query, Zustand, Redux, or similar tools.
• Familiarity with Three.js, React Three Fiber, WebGL, WebGPU, or other visualisation technologies.
• Experience with developer tools, cloud platforms, analytics, or infrastructure products.
• Knowledge of machine-learning or scientific-computing workflows.
• Experience building multi-tenant B2B products.
• Familiarity with Storybook, design systems, accessibility, and internationalisation.
• Experience with Keycloak or another enterprise identity provider.

We are looking for a senior backend engineer to build a high-performance service for streaming large datasets.

This is not a conventional CRUD backend role. You will work on persistent HTTP/3 connections, asynchronous I/O, object-storage range reads, binary data transfer, authentication, request scheduling, etc.

What you will do

• Design and build the data-streaming service in Python.
• Implement HTTP/3 and QUIC-based client-server communication.
• Integrate with S3-compatible object storage.
• Build request prioritisation, cancellation, retries, caching, and backpressure.
• Implement token-based authentication and fine-grained access control.
• Integrate Python services with native libraries and binary data formats.
• Add metrics, tracing, load testing, and failure recovery.
• Work closely with desktop visualisation and Python/ML client teams.
• Benchmark streaming performance against download-first workflows.

What we are looking for

• Strong production experience with Python.
• Experience with asynchronous Python, task scheduling, and concurrent I/O.
• Experience building high-throughput or low-latency backend systems.
• Good understanding of networking, HTTP, TLS, and binary protocols.
• Practical knowledge of S3, MinIO, Ceph, or similar object storage.
• Experience with streaming I/O, byte-range reads, caching, and memory management.
• Strong performance-profiling and debugging skills.
• Ability to design stable interfaces between independently developed systems.

Nice to have

• Production experience with C++. 
• Experience with HTTP/3, QUIC, WebTransport, or high-performance RPC.
• Background in distributed storage, CDNs, databases, filesystems, or media streaming.
• Familiarity with scientific visualisation, HPC, simulation, or large multidimensional datasets.
• Experience with CUDA or GPU data pipelines.
• Experience with OAuth, OIDC, JWT, and capability-based access.
• Knowledge of Kubernetes and OpenTelemetry.
