Your mission
About Corealis
Corealis Consulting stands for the implementation of profound changes that start at the core of the organization. We create lasting impact through clear structure, substantial content and targeted empowerment. Our approach guarantees not only strategic clarity, but also measurable and long-term results.
Rethinking consulting through applied AI
Corealis is building a structured AI platform that changes how consulting work is delivered and how our clients run their programs. Our goal is less time lost looking for information, more transparency and confidence in every decision.
Your Mission
We are hiring for two focus tracks. You apply once and tell us which track fits you better as profiles rarely cover both, and that is expected.
Track A — Data, Infrastructure & Integrations
You build the infrastructure and the data/integration layer:
Plan, develop, deploy, test and operate our AI systems on our Azure infrastructure
Build source connectors against official APIs, including Microsoft Graph, Jira and others
Implement robust sync engineering: resumable backfills, rate-limit and throttling discipline, queue-driven workers
Deploy and manage relational databases like PostgreSQL, as well as vector databases for LLMs (RAG)
Develop and deploy MCP servers (Model Context Protocol) to expose additional tools, skills and data to our LLM systems
Create mock source servers and integration tests to verify the resources and pipelines work correctly
Ensure all developments and deployments are built with security and data privacy in mind
Track B — AI/ML Application Development
You build the applications consultants and clients interact with:
Develop novel tools and software for consulting and our clients based on defined project packages
Create autonomous AI agents and long-lasting automations to boost productivity and elimination of repetitive tasks
Use AI-assisted development as the default: you work with modern AI coding tools daily, test against written specifications, with automated review gates
Help to design and develop an end-to-end pipeline for AI-assisted software engineering (code generation, deployment, build, artifact/log feedback back to code and developer/AI)
Maintain a strong interest in AI and its latest technological developments
