Senior Fullstack Engineer – AI-Native Platform

This is a fully remote position, open to applicants in Germany.

📋 Description

• Design and enhance the architecture of our autonomous agent swarm — establishing agent boundaries, data flows, and the feedback loops that enable bees to self-correct and implement features from start to finish.

• Build and take ownership of the infrastructure that supports our AI-native pipeline, utilizing various AWS services such as Lambda functions, DynamoDB, and SNS/SQS.

• Lead with comprehensive technical specifications — if the logic isn’t documented in the spec, it doesn’t exist — converting complex product requirements into precise, agentic-ready designs that act as the definitive source of truth for AI-driven implementation.

• Guide and assess coding agents and LLM models, evaluating their outputs against a high-quality mental model to ensure accuracy, performance, and security.

• Expand and maintain our TypeScript/Fastify backend and React micro-frontend architecture, enhancing observability, reliability, and test coverage throughout the stack.

• Establish and uphold guardrails, monitoring systems, and self-healing mechanisms that ensure autonomous agents function safely in a production environment.

• Collaborate with Engineering and Product leadership to define the long-term vision of AI-native development at HiveMQ.

• Remain at the cutting edge of AI tools, agent frameworks, and LLM capabilities, continually refining how the hive thinks and builds.

⛳️ Requirements

• A robust software engineering foundation (5+ years) with practical experience in architecting and delivering full-stack applications using TypeScript, Node.js, and React.

• Hands-on experience with AWS infrastructure — including Lambda, DynamoDB, and associated services — with a clear understanding of potential issues at scale.

• Extensive experience working with AI coding agents and LLM-integrated workflows, with the ability to guide them effectively rather than merely prompting.

• A DevOps-oriented mindset — you have implemented the monitoring, alerting, and self-healing systems that maintain the health of production environments without constant human oversight.

• Strong architectural capabilities concerning bounded contexts, idempotent design, decoupled micro-frontends, and distributed systems.

• The ability to convert vague product objectives into clear, agentic-ready technical specifications, leaving no room for misinterpretation.

• A strong sense of ownership and initiative — you actively identify bottlenecks, offer solutions, and execute without needing prompts.

• Excellent English communication skills and the ability to collaborate effectively across engineering, product, and leadership teams in a remote-first setting.

🏝️ Benefits

• Competitive salary and performance-based bonuses.

• Flexible working hours and the option for remote work.

• Opportunities for professional development and continuous learning.

• A collaborative and innovative work environment.

• Health and wellness programs to support employee well-being.
