Jobs at Djinni

We're hiring a Senior Software Engineer to join us for a long-term engagement with a fast-growing UK travel tech client. The role focuses on owning and evolving their production document AI pipeline (OCR plus ML inference on passport and ID documents, CPU only deployment, no GPU).

This is hands-on production engineering, not research. You'll be improving OCR accuracy, optimizing CPU inference (INT8 quantization, ONNX Runtime, batching), refactoring pipeline complexity, and improving observability of a system serving enterprise clients at scale.

What you'll do:

• Take ownership of the existing OCR and document understanding pipeline in Python
• Optimize ML inference for CPU production (ONNX Runtime, quantization, batching, kernel tuning)
• Improve OCR accuracy, latency, throughput, and memory efficiency
• Refactor architectural complexity and reduce technical debt
• Work across ML systems, backend services, APIs, and data pipelines
• Help shape architectural decisions as the platform scales

Required:

• 5 plus years of professional Python software engineering
• Strong experience with OCR and document processing pipelines
• Familiarity with LayoutLMv3, Doctr, PaddleOCR, EasyOCR, Donut, or DocFormer
• Production ML systems experience (not just notebook experimentation)
• ONNX Runtime, quantization, TorchScript, or related CPU inference optimization
• Strong understanding of PDFs, image preprocessing, bounding boxes, and page segmentation
• Experience with systems serving external customers at scale

Nice to have:

• HuggingFace Transformers production experience
• Enterprise SaaS or aviation/travel tech background
• MLflow, Vertex AI, or similar ML operations tooling
• Distributed systems and backend API design experience

Engagement:

• Fully remote
• Long-term (6 plus months) with potential to expand engineering ownership over time
• Part-time (25-30 hrs/week) or full-time (35-40 hrs/week), depending on candidate availability
• Flexible timezone (engagement requires some overlap with UK working hours)

How to apply:
Send a short note covering relevant OCR / document AI work, production ML systems you've shipped, CPU inference optimization experience, GitHub or LinkedIn, current availability, and timezone.

Required skills

• 2+ years of commercial experience in software testing
• Strong knowledge of Java

The opportunity to grow professionally by participating in the implementation of interesting and complex projects, as well as showing personal initiative.

We’re looking for a Senior Engineer who thrives on unfamiliar problems — someone who can land in a customer’s environment, reverse-engineer poorly-documented vendor APIs, and ship a working integration end-to-end, solo.

What makes you a great fit:

• 5+ years of professional software development experience, including 3+ years of hands-on experience in Python.
• Proven track record in designing and building integrations against third-party REST APIs.
• Comfortable working in unfamiliar codebases and picking up new stacks as engagements demand.
• Upper-intermediate written and spoken English.
• Self-managed in an async remote setting — strong ownership, communication, and time management.
• Curiosity and dive-deep mentality — comfortable when documentation is incomplete or absent.

• AI-as-tool fluency — productive use of Claude code, Copilot, Cursor, or similar for research and implementation.

   

Will be a plus:

• Prior customer-facing engineering experience (joining technical calls, gathering requirements).
• Familiarity with security products (SIEM, EDR, vulnerability management, threat intel, firewalls, etc.).

• Experience working in or alongside a SOC.

   

Why work with us?

• People-first management with minimal bureaucracy
• A friendly company culture, proven by employees who choose to return
• Flexible working hours

• 10 paid recovery days
• Full financial and legal support for independent contractors
• Free English classes, with native speakers or Ukrainian teachers

• Dedicated HR support

   

Your day-to-day in this position:

• Design and build bespoke integrations between our products and customer-specific security stacks — primarily in Python, occasionally in whichever stack the engagement demands.
• Tackle the hardest integration problems: the non-conventional, “out-of-the-books” engagements that standard product connectors can’t cover.
• Own each engagement end-to-end — discovery and technical scoping through implementation, testing, and handover.
• Join customer technical calls alongside PM/CSM to sharpen requirements; drive written follow-up between sessions.
• Reverse-engineer poorly-documented vendor APIs and build robust integrations against them.

• Capture learnings from each engagement and feed them back to the product and integration teams so the next engagement is easier.

   

What is your new project?

• Domain: Computer and network security
• Location: Israel
• Company size: 51-200 employees
• Founded in: 2009
  
  Our next steps:

✅ Intro call with a Recruiter — ✅ Tech livecoding interview — ✅ Tech theoretical + system design interview — ✅ Managerial interview — ✅ HR client interview — ✅ Reference check — ✅ Offer
