About the role:
Foxit is hiring a Software Engineer (Mid–Senior) to help build and scale AI-driven document systems. You’ll work on production services that ingest, manage, retrieve, and reason over large document collections—with a strong emphasis on PDFs and LLM-powered retrieval + analysis (RAG).
This is a hands-on engineering role for someone who enjoys owning critical components end-to-end: from document pipelines and APIs to evaluation, latency, and cost.
- Location: Dublin, Ireland
- Work Mode: Preferred Hybrid (2 Days from Office)
What you’ll do
- Design, build, and operate production-grade Python services powering document and AI workflows
- Own document ingestion and management pipelines, including reliability and scalability
- Implement RAG / semantic search systems that combine LLMs with document retrieval
- Develop and refine prompting and context management strategies for real-world usage
- Build and maintain embedding pipelines and vector database integrations
- Implement and optimise PDF processing (structure, metadata, extraction, layout considerations)
- Design and maintain APIs for document services and AI capabilities
- Deploy and run services using cloud infrastructure and containers
- Establish monitoring + evaluation for LLM quality, latency, and cost
- Mentor junior engineers and help raise engineering standards and best practices
- Collaborate within an experienced team and take direction from team leads and peers
What you’ll bring (required)
- Bachelor’s degree in Computer Science / Software Engineering (or related)
- 4–7+ years professional software engineering experience
- Advanced Python skills (production backend/services)
- Strong experience with LLMs, including prompt engineering and context management
- Proven experience designing RAG and semantic search systems
- Hands-on experience with embeddings and vector databases
- Strong understanding of document management systems
- Solid knowledge of PDF internals, extraction, and layout-related processing
- Experience building and operating production systems (reliability, observability, performance)
- Nice to have (bonus)
- Experience with vLLM, Ollama, or similar inference/runtime tooling
- OCR and layout tooling (e.g., Textract, Tesseract)
- Cloud experience (AWS, Azure, or GCP)
- Docker / Kubernetes (containerisation and orchestration)
- Experience with security, access control, and GDPR-aligned system design
Why Foxit
- Work on AI + document systems at scale, where PDFs and enterprise workflows are core
- Own meaningful parts of the platform end-to-end (build → ship → operate)
- Flexible remote/hybrid options in Ireland, with collaboration in the Dublin area
