• Building user-facing features with a focus on simplicity and top-notch user experience • Working across the stack, from database models to API endpoints and UI components • Improving our real-time data synchronization protocol • Adding teams & collaboration features across the platform • Adding support for user data version history and version control capabilities • Working on API testing automation features and scripting capabilities in the product • Adding support for various formats like OpenAPI, and import/export mechanisms • Integrating parts of the platform to create delightful and consistent overall DX/UX • Adding analytics, monitoring, and alerts to our service

• Architecture Leadership and AI-first Development: Partner with a small team of Software Architects in support of 60+ developers actively enhancing four or more major projects at any given time. • Technical Responsibilities: Help refine plans and architectures to modernize Microsoft stacks to .NET Core and React. • Cross-Functional Collaboration: Success in this role is heavily dependent on working with Professional Services, Support, Security, Product Managements and Engineering in other verticals to ensure low drama, repeatable customer success.

• Own full-stack features end-to-end — from database models and APIs to frontend integration and UX correctness. • Design and extend backend systems that power complex agent orchestration — subagents, skills, knowledge base retrieval, parallel execution, and long-running workflows. • Build and evolve REST APIs that are stable, well-typed, and easy for the frontend and agents to consume. • Integrate and debug LLM-powered workflows — prompts, tools, retrieval, evaluation loops — with a strong focus on reliability and observability. • Ensure frontend and backend systems interoperate cleanly: tight contracts, predictable data flow, and minimal friction. • Improve performance, resilience, and security across the stack as usage and complexity grow. • Use coding agents (Claude Code, Cursor, etc.) as force multipliers to move faster and push quality higher. • Collaborate closely with product and design to turn ambiguous ideas into shipped, production-grade features. • Raise the technical bar through thoughtful code reviews, architectural discussions, and mentorship of junior engineers.

We're looking for a Senior Full-Stack Engineer to join an established trading platform development programme for a large enterprise client. The platform has been live in production for over 7 years, with most of the core team having worked on it for close to 5 years on average — a reflection of the stability, quality, and long-term nature of this engagement. The system is production-critical and actively evolving, with a strong focus on performance, reliability, and maintainability. While Applied Blockchain is well known for distributed ledger and cryptography work, this role is focused on a non-blockchain trading system built using modern TypeScript-based technologies. The role is full stack in nature, though with a slightly stronger emphasis on the frontend (React/TypeScript). You'll be joining a highly experienced team of senior engineers and QA developers, where autonomy, technical ownership, and thoughtful decision-making are expected. What you’ll be doing - Designing, building, and maintaining features across the full stack of an internal trading platform - Working primarily with: - TypeScript (Node.js & React) - Monorepo tooling, GitHub, GitHub Actions - Jest, Playwright - Redis, MS SQL, WebSockets - Docker, Kubernetes - Observability tooling (Grafana, Prometheus, SonarQube) - Taking end-to-end ownership of features from design through to production - Collaborating closely with platform / DevOps engineers on build pipelines, observability, and operational concerns - Communicating directly with the client to clarify requirements and propose solutions - Contributing to and improving automated testing practices - Participating in peer code reviews and helping maintain high engineering standards across the team - Using LLM/AI enabled development tools and techniques (with access to the latest OpenAI/Anthropic/etc. models) as part of day-to-day development
