At Avanquest, we build software that makes digital life genuinely easier, for everyday users and professionals alike, all over the world. Smooth document management, faster and safer devices, and browsing without the hassle: we spot the everyday frustrations and fix them. Millions of people around the world count on us. And we're just getting started.
We're growing fast, and we're hungry for more. With teams across North America and Europe, we tap into a wide range of perspectives to push our thinking further. AI isn't a buzzword here, it's a real engine for change. We use it to sharpen our products, break new ground, and build experiences that actually move the needle.
Creativity and boldness are welcome at every level. We don't want order-takers, we want builders. The best idea wins, no matter who it comes from. Here, personal ambition and team spirit don't compete, they feed each other. If you want to stretch yourself, make a real impact, and win as a team, you're in the right place.
What you'll be responsible for:
Model Serving & API
- Evaluate and deploy open-source LLMs via vLLM, Ollama, or TGI on GPU infrastructure;
- Design and maintain a REST API with auth, rate limiting, versioning, and API documentation;
- Optimize inference: quantization, batching, and concurrency tuning for latency/cost trade-offs;
- Own observability - latency, throughput, GPU utilization, and cost-per-call dashboards.
Web App Integration
- Integrate AI features into our web apps and document processing platforms;
- Build AI-powered UI components: chat interfaces, inline suggestions, smart search, and summarization widgets;
- Collaborate with frontend engineers on UX patterns specific to async and streaming AI responses;
- Manage API keys, usage metering, and per-user AI feature flags on the client layer.
Document Orchestration
- Design multi-step orchestration pipelines for document ingestion, parsing, classification, and extraction;
- Integrate OCR, layout detection, and chunking strategies for PDFs, Word docs, spreadsheets, and scanned images;
- Build RAG pipelines with hybrid retrieval (dense + sparse) over document corpora;
- Design and optimize prompts for extraction, summarization, classification, and conversational AI workflows;
- Implement task queues and async workers to handle high-volume document processing reliably.
Platform & Collaboration
- Define evals and quality benchmarks for extraction accuracy, classification, and generation quality;
- Write technical docs, so the platform is maintainable by the whole team and accessible for technology partners;
- Partner with product, data science, and DevOps/MLOps to ship AI features reliably and at scale;
- Stay current on the open-source model ecosystem and advise on model selection and upgrades.
The profile we're looking for:
- 3+ years of experience across backend, API design, and web technologies;
- Proven track record deploying or integrating LLMs in production (open-source models strongly preferred);
- Hands-on knowledge of REST API design and at least one API framework;
- Experience building AI features in web apps, including streaming and async response handling;
- Familiarity with document processing workflows — OCR, parsing, classification at scale;
- Comfortable designing multi-step orchestration pipelines with task queues, retries, and failure handling;
- Strong communication skills; able to reason about trade-offs across latency, cost, and accuracy with stakeholders.
