Company Description
Hyperscience is a market leader in hyperautomation and a provider of enterprise AI infrastructure software. The Hyperscience Hypercell platform unlocks the value of an organization’s back office data through the automation of end-to-end processes, and transforms complex documents into LLM and RAG-ready data to power enterprise GenAI experiences. This enables organizations to transform manual, siloed processes into a strategic advantage, resulting in a faster path to decisions, actions, and revenue; positive and engaging customer, public, and patient experiences; and dramatic increases in productivity.
Leading organizations across the globe rely on Hyperscience to drive their hyperautomation initiatives, including American Express, Charles Schwab, HM Revenue and Customs, Mars, Stryker, The United States Social Security Administration, and The United States Veterans Affairs. The company is funded by top tier investors including Bessemer Venture Partners, Battery, FirstMark, Stripes, and Tiger Global.
The Role
We are looking for a Senior Back-End or Full-Stack Engineer (with a focus on the back-end mostly) to join the Platform Engine team at Hyperscience and help us take our Flows orchestration capabilities to the next level. This is an exciting time for Hyperscience’s product, business, and people!
You will have the opportunity to influence and deliver on a bold vision for transforming the way organizations model and execute their business processes. There will be many opportunities for growth along the way.
The Platform (Flows)
At the core of our product sits the Hyperscience platform — a tier that allows both non-technical business users and technical partners to define the complex automation workflows (called “flows”) that back the business process and are tailored to the unique customer needs.
Our platform runs and orchestrates these flows in a distributed, horizontally scalable way. The challenges we solve touch on distributed computing, workflow engines, system integrations, building software SDKs, web applications to visualize and edit these flows, as well as UI and generative AI-based logic to generate such flows.
The Technology Stack
Forefront ML research, robust back-ends, and smooth UX are all essential to everything we do — and even more so is the holistic experience they can bring together.
The technology stack is built on Python and Django on top of a relational database on the backend, TypeScript and React on the frontend, and PyTorch for training and running ML models.
How Our Teams Work
- Our team collaborates closely with Product, Design, and other engineers to define and build product features.
- You will contribute across the entire software development lifecycle, including requirements definition, design, development, testing, deployment, and operations.
- While your work may be focused on a particular aspect (i.e, the backend of the application for this position), you will still always be expected to think about the big picture and the holistic experience.
- You will do so in an environment where teams own their own domains and drive their roadmaps bottom-up.
- We believe in bottom-up autonomy with top-down alignment. We look for people who want to contribute their ideas to help us continue getting better.
- We also look for people who have a strong sense of teamwork and want to collaborate effectively and support each other.
Responsibilities
- Collaborate cross-functionally with Product Managers, Designers, and other engineers, including Front-end, Machine Learning, DevOps, and QA engineers.
- Partner with the Product and Design teams to solve functional problems even when the initial answer is not fully defined.
- Creatively solve technical challenges in the face of competing tradeoffs.
- Leverage your knowledge to design, build, and deliver scalable and resilient features.
- Ensure product quality and code quality by writing automated tests and performing thorough code reviews and design reviews.
- Truly own the features you lead — from making sure we are building the right thing, to making sure a feature truly adds customer value after it is done.
- Mentor engineers who are less experienced than you. Be ready to help.
- Be open to learning: We have a highly talented team at Hyperscience, you will have plenty of learning opportunities and will be fully supported to learn and grow.
Qualifications
- Strong common sense, logical thinking, and a solid computer science basis are all necessary when working on this product.
- Strong command of English and good communication skills are essential — we have almost daily discussions with our colleagues in the USA and the UK.
- Experience with Python is required.
- Experience with SQL and relational databases is a strong plus.
- Django and its ORM are central for our product. Experience with it is a plus.
- Willingness to work (or learn to work) across the full-stack is not a requirement, but will be encouraged and supported here. We like it when engineers can deliver a feature end-to-end across the full technology stack.
- Previous experience with the front-end technologies we use — TypeScript, React — is also a plus, but not a requirement.
- Using AI to write code is neither required, nor frowned upon here. If it makes you more productive — great, we offer licenses for Copilot and Gemini.

- You’ll work in one of the most innovative tech companies in Sofia
- Work-from-home flexibility
- Up to 4 months of fully paid parental leave used within 3 years of your child’s birth
