Infrastructure Engineer

• Ingestion Pipeline: Own and accelerate our migration from legacy daily tasks to a high-throughput, real-time stream processing ingestion pipeline.
• Infrastructure Scaling: Manage service provisioning and scaling infrastructure, including expanding our adoption of Kubernetes.
• Database Management & Optimization: Ensure database consistency and optimize complex operations, specifically utilizing Postgres, to maintain high performance under heavy resource usage.
• Automation: Support and evolve our real-time auto-moderation pipeline, collaborating with the Product Engineering team to further develop the feature.
• Cross-Functional Collaboration: Work closely with different squads and various stakeholders. You will directly translate business requirements into technical execution.

Python Software Engineer – Product Infrastructure

• Collaborate with developers and satellite operators to foster a strong **SatDevOps culture**.
• Design, implement, and maintain **scalable, reliable, and secure infrastructure** in a hybrid cloud environment.
• Improve our **developer experience** by building better tools, workflows, and environments.
• Lead efforts to automate and optimize systems, including **CI/CD pipelines**, **infrastructure provisioning (IaC)**, and deployment workflows.
• Own and evolve our **observability stack** (metrics, tracing, logs) to improve usability and performance. Grafana-centric ecosystems are a plus.
• Implement and advocate for **best practices** in software reliability, fault tolerance, and performance tuning.
• Proactively **identify, investigate, and resolve system reliability issues**, performing root cause analyses and implementing long-term fixes.
• Partner with teams to design and operate **Software Defined Network (SDN)** solutions.
• Contribute to a **collaborative and inclusive team culture** where respectful debate and continuous learning are celebrated.

Senior Cloud Infrastructure Engineer

• Design target architectures (SDN, Cloud, and Containers).
• Perform impact studies and conduct Proofs of Concept (POC).
• Write Technical Architecture Documents (TAD).
• Oversee operational maintenance of the VMware VCF/NSX stack.
• Perform security hardening of Linux systems and Kubernetes clusters.
• Design and maintain reusable Terraform modules.
• Optimize the lifecycle of containerized workloads.
• Industrialize deployment pipelines.
• Resolve complex incidents (Level 2/Level 3) in compliance with SLAs.
• Collaborate with specialized teams.

Infrastructure Engineer, Senior

• Build robust, flexible, and scalable RL and post-training pipelines, including smoke tuning runs for quality testing and approach ablations
• Design data control systems that govern what the model sees, when it sees it, and how training data flows through rollouts, replay, filtering, evaluation, and policy updates
• Tune training and inference end-to-end for high throughput across the systems that matter: networking, memory, compute scheduling, data loading, storage, checkpointing, and I/O
• Investigate how infrastructure choices affect learning dynamics, eval quality, model behavior, and training stability – staying close to the state of the art in LLMs, RL, and post-training
• Build infrastructure for model iteration: experiment runs, artifacts, evals, dashboards, failure inspection, reproducibility, and cost visibility
• Work on inference infrastructure where it affects post-training and evaluation loops
• Build and improve agentic development environments: coding-agent harnesses, browser/tool integrations, terminal/runtime sandboxes, repo-aware workflows, and multi-agent orchestration
• Work closely with the team: plan future steps, discuss tradeoffs, share context early, and stay in touch while building

ML Infrastructure Engineer

• Lead projects that improve the maintainability and scalability of our cloud infrastructure
• Own day-to-day infrastructure operations, solving problems directly or making sure they are dispatched to the right team
• Coach other tech team members on how to best leverage the capabilities of our cloud infrastructure

• Ensure administration and operational maintenance of system infrastructures.
• Administer and evolve virtualization environments and private cloud.
• Manage storage, backup and network infrastructures.
• Provide support and expertise for middleware platforms.
• Participate in infrastructure evolution, migration and transformation projects.
• Analyze and resolve complex level 2 and 3 incidents.
• Contribute to the automation of operational tasks and continuous improvement.
• Take part in migration and replacement operations for critical components (databases, middleware, technical platforms).
