Join AiMi and build the future of Capital Markets Infrastructure
At AiMi, we are revolutionising the management of critical trading and market data infrastructure through AI-driven automation. By leveraging advanced technologies, we replace manual, static processes with dynamic, data-driven workflows that enable organisations to achieve greater efficiency, agility, and control.
We operate at the cutting edge of agentic AI - deploying autonomous agents that ingest venue and vendor notifications, assess impact across client infrastructure, and drive change management workflows in real time. If you're technically strong, AI-curious, and want to ship meaningful work on a live production platform, we want you on the team!
Tasks
What you’ll do:
As an AI Software Engineer, you will work across the full stack of the AiMi platform. Building and shipping features from intuitive front-end interfaces through to robust back-end services and the agentic AI workflows that sit at the heart of our product. You will own features end-to-end, contribute directly to our agent pipeline, and play an active role in shaping how we build software as a team.
Key responsibilities include:
- Build and ship new features and functionality that directly serve our clients: across back-end services, agentic workflows, and integrations that power the platform.
- Contribute to the development and continuous improvement of our agentic AI pipeline, translating complex capital markets workflows into reliable, production-grade agent behaviour
- Design, build, and maintain skills, connectors, and MCP-based integrations that extend the capabilities of AiMi agents — connecting to client systems, internal tooling, and third-party platforms
- Contribute to agent evaluation - designing and running evals that assess agent accuracy, reliability, and behaviour across real-world workflows, and using those insights to drive continuous improvement
- Participate in agentic SDLC practices: spec-driven development as part of day-to-day engineering workflow
- Build and maintain robust back-end services container and serverless based services and APIs in Node.js , with a working understanding of our React/TypeScript front-end codebase
- Improve LLM observability and traceability across the agent pipeline to monitor, evaluate, and iterate on agent performance
- Work across the full stack: React/TypeScript front-end, Node.js back-end services, and AWS Lambda - to deliver well-tested, maintainable code and scalable services.
Requirements
What we’re looking for
- 4 to 7 years of hands-on full stack development experience
- Solid back-end development experience in Node.js, with experience building and consuming RESTful APIs
- Practical experience working with LLMs, agent frameworks, or AI automation tooling: Mastra, LangChain, LlamaIndex, Claude, OpenAI or similar
- Familiarity with agentic SDLC practices and spec-driven development workflows (Claude Code, Cursor, CodeRabbit, or similar)
- Working knowledge of AWS cloud services - Lambda, Bedrock, DynamoDB, S3, Cognito, API Gateway, CloudWatch
- Experience with MongoDB and DynamoDB (or equivalent NoSQL databases)
- Solid understanding of event-driven architecture patterns
- Comfortable with testing at multiple levels - unit, integration, and E2E - and a genuine commitment to developer led testing approaches
- Familiarity with CI/CD workflows, GitHub Actions, and version control best practices
- A pragmatic, ownership-driven mindset with the ability to work independently in a remote, fast-paced environment
- Clear written communication skills - important for async collaboration and for working within our spec-driven development process
Good to have
- Domain knowledge in capital markets, trading infrastructure, market data, or financial services
- Experience with LLM observability tooling such as Langfuse, Helicone, or similar
- Familiarity with streaming architectures and server-sent events (SSE)
- Exposure to PostHog or other feature flag and analytics tooling
Benefits
What you’ll gain
- Hands-on experience building and shipping production-grade agentic AI in a live finanical markets platform.
- Deep exposure to modern AI engineering, LLM evaluation, agent observability, prompt engineering, and agentic SDLC practices as part of daily work.
- Direct involvement in architectural decisions at an early-stage, fast-moving startup. Your work will have real, visible impact.
- Practical insight into capital markets infrastructure and trading operations.
- Opportunity to grow into a senior or lead engineering role as AiMi grows.
- Collaborative, remote-first team culture with a strong engineering discipline.
Let’s Go!
If you’re excited to be part of a forward-thinking company at the intersection of finance and technology, we’d love to hear from you. Apply now and help shape the future of AiMi!
