About 9H
9H is a creative-tech company that builds the systems, brands and digital experiences that power modern businesses. We combine strategy, creativity and technology to turn ideas into real results, helping our clients work faster, smarter and with more confidence as they scale.
Headquartered in Malta (EU), with delivery and commercial teams across Europe, the Middle East and North Africa, we work with ambitious, forward-thinking clients, including leading brands across the region. We’re growing with intention, focused on simplicity, sustainability and building work that lasts.
We value people who are curious, proactive and take ownership of what they do. In return, we offer an environment where you’re trusted to do your best work, supported to grow your skills, and encouraged to build a career that fits your life, not the other way around.
About the Role
We’re looking for a Python backend/integration engineer to build reliable APIs and integrations between our AI platform and real-world enterprise systems (ERPs, accounting tools, internal data platforms).
No frontend work. No ML background required. Strong systems thinking matters more.
As an Integration & Systems Engineer at H6.ai (by 9H), you’ll work closely with our Chief AI Officer / CTO and platform engineers to design, build, and run the integration backbone of our AI platform. H6.ai delivers trusted, explainable AI systems for finance and operations teams. Your work ensures our AI agents integrate reliably, predictably, and safely into complex enterprise environments.
What You’ll Do
- Build and operate integrations between H6.ai and external systems (ERPs, accounting platforms, internal databases)
- Design and maintain backend services, REST APIs, and data pipelines
- Implement async workflows (webhooks, retries, idempotency, error handling)
- Normalise and validate real-world enterprise data (yes, it’s messy)
- Engineer quality into systems through automated tests and validation rules
- Support multiple client integrations while keeping reliability and clarity high
How We Think About Quality
At H6.ai, QA is part of engineering, not a separate function. You’ll:
- Write automated tests for integrations and APIs
- Encode basic financial and data checks (e.g. totals, tax, currency consistency)
- Ensure deterministic behaviour — the same input should produce the same output
- Help prevent regressions as the platform evolves
What We’re Looking For
- 3+ years of experience in backend or systems integration engineering
- Strong Python skills
- Experience designing and consuming REST APIs (JSON)
- Solid understanding of databases and SQL
- Experience with async systems, webhooks, or event-driven architectures
- Comfortable working with real-world enterprise data
- Able to manage multiple integrations in parallel
Nice to Have (not required)
- Experience with ERPs, accounting, or finance systems
- CI/CD pipelines and automated deployments
- RPA or workflow automation tools
- Data engineering or validation frameworks
- Exposure to AI-powered or document-processing systems
Why Join H6.ai (part of 9H)?
We don't care about hustle culture. We value doing better work, building smarter systems, and creating a future we’re proud of.
- Be part of a supportive, diverse and collaborative team
- Take real ownership of your work and see the impact you create
- Work in a flexible environment that values focus and autonomy
- Learn and grow through exposure to modern tools, technologies and AI-driven solutions
- Contribute to a company focused on long-term sustainability, not short-term wins
- Grow your career with purpose, clarity and direction
