Job Description

The Role

We're seeking a Software Engineer specialized in AI/ML applications to independently drive the development, evaluation, deployment, and end-to-end lifecycle management of AI-powered systems. This role sits at the intersection of advanced AI application development, robust software engineering, and continuous automation: you'll build the systems, and you'll build the machinery that keeps them tested, secure, and running at scale.

This position goes deep on infrastructure and reliability: deploying and scaling open-source models across distributed GPU infrastructure, designing automated testing frameworks that cover both deterministic code and stochastic AI outputs, and implementing secure CI/CD pipelines that enforce quality on every merge.

This role is built for an engineer who takes high ownership: comfortable carrying a feature from ideation through architecture, build, evaluation, and production, and rigorous enough to prove with benchmarks and dashboards that the system actually works.

What You'll Do

• Architect and scale AI infrastructure: deploy and scale open-source models using distributed orchestration frameworks (Kubernetes, Ray, or Slurm) to run highly available, fault-tolerant AI workloads across multi-node clusters.
• Design and evaluate AI systems: run experiments, prompt-tune, evaluate, and deploy production-grade models and AI agents, with flexible mechanisms to benchmark performance and swap models quickly as use cases evolve.
• Drive error and gap analysis: run comprehensive model benchmarks, perform deep error and gap analysis on model outputs, and build analytics dashboards that communicate system performance clearly to stakeholders.
• Build automated testing at depth: develop extensive automated test suites that validate end-to-end application code, aggressively improving coverage across both standard software and stochastic AI outputs.
• Automate DevSecOps: keep systems clean and secure by automating vulnerability scanning on GitLab Merge Requests and implementing fast remediation pipelines for identified issues.
• Execute independently: own features from ideation to production, including architectural decisions, public/private repository synchronization, and open-source community interactions.

What We're Looking For

• 6+ years of professional experience writing production-grade, asynchronous Python, with a strong focus on decoupled, clean system architecture and design patterns.
• Deployment & orchestration: hands-on experience deploying, monitoring, and scaling models in production using Kubernetes, Ray, or Slurm, including multi-node cluster configurations.
• Hardware & scaling optimization: strong understanding of GPU memory management and infrastructure-level tuning for high-throughput, low-latency AI inference workloads.
• AI evaluation & frameworks: deep experience building with LangChain, Hugging Face libraries, MLOps, vLLM, and SGLang, with proven expertise in prompt engineering, automated model benchmarking, and systematic LLM evaluations.
• Data analysis: proficient in Python-based analysis (pandas, NumPy, or similar), able to extract insights from evaluation results and communicate findings clearly to technical and non-technical audiences.
• CI/CD & security automation: advanced knowledge of GitLab pipelines, including automated test jobs and vulnerability scanners integrated directly into the MR workflow.
• Testing toolchains: expert familiarity with Python testing frameworks (PyTest), mocking libraries, and automated test generation approaches for AI workloads.
• Advanced version control: high proficiency in advanced Git workflows, including rebase strategies, cryptographic commit signing, and complex public/private repository mirroring.
• Bachelor's or Master's degree in Computer Science, Engineering, or a related field (or equivalent experience).
