Are you passionate about automation and developing cutting-edge solutions? Cernel is on a mission to automate repetitive tasks for e-commerce businesses using AI agents powered by data. We're looking for a Senior Backend Developer to join our team and help us revolutionize the industry.
Develop AI agents that empower e-commerce businesses We're building a revolutionary AI system that analyzes data and automates optimization tasks, leading to higher rankings, conversions, and happier employees with more time for creative work.
Who are you?The role of Senior Backend Developer will focus on developing and maintaining new, exciting solutions which underline our ability to provide customers with AI e-commerce specialist agents.
You have an innate interest in development, are detail-oriented, and take responsibility for your work. You have an understanding of solid, practical development principles and experience in operating and evolving a tech stack to handle scale.
We value honesty, data-driven decisions, and ownership Our team is collaborative and thrives on open communication. You should enjoy the responsibility and autonomy of working in a startup as you will become a key resource in building the system that enables further realization of Cernel's mission.
You should have hands-on experience with iterative development processes and making decisions that balance short-term and long-term requirements. The role will help define and implement the technology necessary to scale our AI agents to a global market.
You will work closely with the CTO to support AI development teams and will be given shared responsibility for developing solutions and setting a direction for code development.
Qualifications- A strong coding background is essential While a degree is a plus, we value experience over formal education.
- Operational experience is valued highly. We are looking for someone that has seen things go wrong and has practical experience in operating those systems for an extended period of time.
- A minimum of 4-5 years of coding experience in ideally Python (preferably using frameworks such as Django, Flask, FastAPI, and Celery).
- Primary experience with other frameworks and programming languages is not a deal-breaker as the most important qualities are open-mindedness, willingness to learn, and a fundamental understanding of what good software development is.
- Effective problem-solving abilities to address technical challenges and optimize backend functionalities.
We work with an event-driven architecture that continuously monitors and acts upon large amounts of data to drive value for e-commerce shops. Our infrastructure ingests large amounts of data from customers, processes it, analyzes it, and using algorithms provides and executes optimizations autonomously on the webshop.
Responsibilities
- API Development of our Public API, Internal APIs, and 3rd party integrations.
- Development and scaling of core business offerings, including state layer (Graph Database, SQL databases).
- Help maintain and scale existing AI services.
- Help to support our AI operations through the development of new systems. This could include 3rd party integration development, data pipelining development of tools to help support core business offerings.
- Implementing development guidelines and helping define code quality. Defining abstractions and how the systems should interact outside of our domain.
You will get the chance to work with the below technologies, but also help define our system of the future:
- Graph databases
- Python
- Celery (Event-Driven System)
- Data management (Big Query, Google Cloud Engine, S3, Data Lakes, AWS)
- API consumption and distribution (GraphQL and REST)
- Agentic AI frameworks (PydanticAI, Swarm)
- Server Infrastructure (Debian/CentOS)
- Nginx (Networking)
Cernel is an e-commerce automation startup founded in early 2023. We are a team of six people but are actively hiring and expanding the team to support our growth.
We have recently received venture capital funding, which includes private funds from founders and employees from team.blue, Humio, and Google as well as a list of experienced e-commerce specialists to further develop our solutions. You will therefore work in a highly technical and skilled environment with an automation-first approach to solving complex problems.
BenefitsWe offer several benefits, including but not limited to:
- Competitive pay
- Stock options are a possibility
- Hybrid work allowed
- Central office in Aarhus
- Upskilling opportunities such as certifications, events, and programmes
