ABOUT JENTIC

At Jentic, we’re on a mission to build the core integration layer for AI, enabling developers to connect their AI systems to the world’s APIs easily and securely. We’re creating a critical missing piece of the future AI tech stack — middleware designed from the ground up for the AI era.
We’re not just building an AI-facing product, but an AI-native company. We’re building a small highly-productive team, in which everyone is amplified with AI, and where everyone shares personal and financial ownership in our mission. Joining Jentic means shaping the future of software in a team that is built for the future.

WHAT WE’RE LOOKING FOR:

We’re seeking an individual who:

• Has 7+ years experience building production software, with a strong emphasis on backend development.
• Has deep experience designing and scaling RESTful APIs — including authentication, authorization, rate-limiting, and versioning.
• Is highly proficient in Python, with FastAPI experience preferred.
• Understands distributed system design, service-oriented architecture, and how to scale services in cloud environments (e.g., AWS, GCP, Azure).
• Has worked with databases at scale (both relational and NoSQL), caching systems, and async task queues.
• Builds with performance, maintainability, and observability in mind (metrics, logs, tracing).
• Thrives in a fast-paced, ambiguous environment — and takes initiative without waiting for marching orders.
• Has a track record of building complex systems from scratch or modernizing legacy ones.
• Is curious about AI and wants to help figure out how it intersects with software architecture.
• Brings entrepreneurial energy: whether through startups, open source, or solo projects, you’ve built things under your own steam.
• Is excited by the chance to work at an ambitious, properly-funded Irish startup solving hard problems in AI.

As a software engineer for our core product, you will:

• Design and implement robust, scalable APIs and backend services from the ground up.
• Develop core platform features such as authentication, authorisation, and role/permissions management, integrating tightly with our Agentic API layer that powers open-source AI workflows.
• Collaborate closely with the CTO and leadership team to shape the architecture and long-term technical strategy of our AI-native platform.
• Lead backend development initiatives, making key technical decisions and driving delivery of high-impact features.
• Take ownership of system performance, reliability, and maintainability — ensuring our backend can scale with the business.
• Stay close to emerging AI technologies and help assess how they can be incorporated into our stack.

• Contribute across the full stack where needed.Grow into a technical leadership position as the company scales, mentoring engineers and influencing culture.

Please note:

• This role is primarily an office-based role (4 days per week, with flexibility) in our city centre location in Dublin 2.
• This is a mid-level to senior role — you should already be operating as a Senior Engineer level or higher.
