Job description
Orcrist is building a next generation data intelligence platform using cutting-edge technologies. We're handling petabyte-scale data with sub-second queries. Our product is a Kubernetes‑based platform delivered as B2B SaaS or as a self‑hosted on‑prem solution, including air‑gapped deployments. We enable customers across defense, law enforcement, and enterprise to turn mission-critical data into actionable intelligence.
Role
We are looking for a hands-on ML Engineer to build and productionize modern AI capabilities across text, vision, audio, and other applied ML use cases. You will work directly with state-of-the-art and open-source models — testing, evaluating, optimizing, and fine-tuning them for real product use cases. This is not a role focused on training foundation models from scratch or building data pipelines only. You will work closely with Research, Product, and Data Engineering teams to take promising models and ideas from experimentation to reliable, production-ready systems.
What you’ll do
- Evaluate, compare and integrate open-source models for concrete product and customer use cases.
- Build and improve LLM-based applications.
- Extend and improve AI and ML models using inference optimization, evaluation, and fine-tuning where appropriate.
- Work with NLP, translation, speech-to-text / ASR, image and document understanding, and related applied AI models.
- Design evaluation frameworks covering model quality, latency, reliability, and cost.
- Take models from experimentation into production, including packaging, deployment, monitoring, and iteration.
- Optimize inference performance and operational cost.
- Collaborate with Research and Product teams to turn prototypes and experiments into scalable product capabilities.
- Contribute to modern ML infrastructure and MLOps while remaining hands-on with models and model behaviour.
About you
- 4+ years of experience in Machine Learning Engineering, Applied AI, or a similar hands-on ML role.
- Strong Python skills and practical experience with modern ML frameworks and libraries such as PyTorch, Transformers, and Hugging Face.
- Experience working with LLMs, NLP models, speech models, or other modern generative AI systems.
- Hands-on experience evaluating and experimenting with existing models rather than only building ML infrastructure.
- Experience with inference engines like vLLM or SGLang, and platforms like NVIDIA Triton or Ollama.
- Familiarity with fine-tuning, prompting, model evaluation, inference, and deployment.
- Working understanding of AI model encoding and quantization formats, and the tradeoffs thereof.
- Strong engineering mindset and ability to turn experiments into reliable, reproducible systems.
- Eligible to work in Germany; export-control screening required for certain programs.
Nice-to-haves
- Hands-on experience with model serving and production deployment, using technologies such as Kubernetes, KServe, NVIDIA Triton, and/or Ray Serve.
- Knowledge of inference optimization techniques, including batching, quantization, ONNX, or TensorRT.
- German language skills (B1+) and/or familiarity with defense or public safety datasets.
- Exposure to geospatial AI, satellite imagery, or remote sensing.
- Experience working in constrained or regulated environments with infrastructure, security, or deployment requirements.
What we offer
- Remote-first, Germany-wide: Work from wherever you do your best work, with regular team gatherings in Berlin and other off-site locations.
- Flexibility by default: Flexible working hours help you make work fit your life.
- Your setup, your way: Get a personal home-office equipment budget to create a workspace that works for you.
- 30 days of vacation: Take the time you need to recharge and come back with fresh energy.
- Keep growing: We invest in your personal and professional development.
- Get rewarded for impact: Performance bonuses are tied to agreed objectives and key results.
- A warm welcome: Every new team member gets a welcome goodie bag.
- Good people, good times: From summer and Christmas parties to regular team gatherings, we make time to celebrate together.
- A mission that matters: Work on challenges with tangible impact on public safety and national security.
Prepare your application
Use the description above to assess your fit for orcristtechnologies. This checklist is guidance from Resumize, rather than additional requirements from the employer. Imported listings can be shortened or change after collection, so confirm the complete description and current availability before sending an application.
Match requirements to evidence
Identify the responsibilities and skills the employer explicitly names. For each important requirement, choose one example from your work, education, training, or projects. Explain what you did, how you did it, and what changed as a result. Include a measurable outcome when you can support it. If you lack a requirement, describe related experience accurately instead of adding an unfamiliar skill to your resume.
Put the most relevant examples near the top of your resume. Keep job titles, dates, qualifications, and contact details consistent across your application materials. Use the employer’s terminology when it describes your experience accurately; a copied list of keywords does not explain your contribution. A short, specific bullet is easier to review than a paragraph that mixes several unrelated duties.
Check the working arrangement
Confirm the location, schedule, employment type, and any eligibility requirements on the employer’s site. A remote label does not establish worldwide eligibility or flexible hours. If compensation, benefits, equipment, travel, or contract duration are missing from this listing, write down your questions for the recruiter. Do not assume details from another opening at the same company apply to this role.
Review before submitting
Follow the employer’s requested file format and application instructions. Open your exported resume and check that its text is selectable, its sections read in order, and its links work. Proofread names, dates, and contact information. Share confidential work samples only when you have permission, and use an anonymized example when necessary.
Submit through a trusted employer or recruiting destination. If the original listing has disappeared, search the employer’s careers page for the title rather than assuming the vacancy remains open. Save the application date, job reference, and the version of your resume you sent. Those details help you prepare for a later conversation and avoid submitting conflicting information through several job boards.
Review your resume for writing and readability feedback, or browse other openings if this opportunity is unavailable.
