About this role

We are seeking a Product-Minded Junior Infrastructure Engineer to join our growing team. This is a "70/30" role: you will spend 70% of your time on hardcore backend and infrastructure—tackling complex distributed systems—and 30% of your time building intuitive internal tools that transform our platform capabilities into a seamless product experience for researchers. You will design, build, and operate distributed data systems that power large-scale ingestion, processing, and transformation of datasets used for AI model training.

This is a versatile role: you’ll own end-to-end pipelines, ensure data quality and scalability, and collaborate closely with ML researchers to prepare diverse datasets for cutting-edge model training. You’ll thrive in our fast-paced startup environment, where problem-solving, adaptability, and wearing multiple hats are the norm.

Key Responsibilities

Distributed Systems & Orchestration (70% - Core Engineering)

• Participate in the design and implementation of distributed task orchestration systems using Temporal or Celery.

• Architect pipelines across cloud object storage (S3, GCS), data lakes, and metadata catalogs.

• Implement partitioning, sharding, and caching strategies to ensure data processing pipelines are resilient, highly available, and consistent.

Core Data Pipelines

• Design, implement, and maintain distributed ingestion pipelines for structured and unstructured data (images, 3D/2D assets, binaries).

• Build scalable ETL/ELT workflows to transform, validate, and enrich datasets for AI/ML model training and analytics.

Pretrain Data Processing

• Support preprocessing of unstructured assets (e.g., images, 3D/2D models, video) for training pipelines, including format conversion, normalization, augmentation, and metadata extraction.

• Implement validation and quality checks to ensure datasets meet ML training requirements.

• Collaborate with ML researchers to quickly adapt pipelines to evolving pretraining and evaluation needs.

Infrastructure & DevOps

• Use infrastructure-as-code (Terraform, Kubernetes, etc.) to manage scalable and reproducible environments.

• Manage data assets using Databricks Asset Bundles (DABs) and build rigorous CI/CD pipelines (GitHub Actions).

• Focus on maximizing cluster utilization (CPU/Memory) and optimizing EC2 instance allocation to aggressively reduce compute costs.

Product & Internal Tooling (30% - Interface & DevEx)

• Take ownership of the platform’s "Interface" by building Data Explorers and management consoles using React or Next.js.

• Actively listen to researchers and data scientists to iterate on UI/UX based on their feedback.

• Simplify complex CLI operations into intuitive GUI interactions to boost overall developer experience (DevEx).

Required Qualifications

Technical Background

• 2+ years of experience in software engineering, backend development, or distributed systems.

• Strong programming skills in Python (plus Scala/Java/C++ a plus).

• Familiarity with distributed frameworks (Spark, Dask, Ray) and cloud platforms (AWS/GCP/Azure).

• Experience with workflow orchestration tools (Temporal, Celery, or Airflow).

• Proficiency with Infrastructure as Code (Terraform) and CI/CD tools (GitHub Actions).

Frontend & User Experience

• Experience building web applications or internal tools using React or Next.js.

• A "product-first" mindset: an interest in how users interact with infrastructure and a desire to build clean, functional interfaces.

Domain Skills (Preferred)

• Experience handling large-scale unstructured datasets (images, video, binaries, or 3D/2D assets).

• Familiarity with AI/ML training data pipelines, including dataset versioning, augmentation, and sharding.

• Exposure to computer graphics or 3D/2D data processing.

Mindset

• The 70/30 Specialist: You enjoy deep systems engineering but are equally excited to build the UI that makes those systems accessible.

• Comfortable in a startup environment: versatile, self-directed, pragmatic, and adaptive.

• Strong problem solver who enjoys tackling ambiguous challenges and "0 to 1" building.

Preferred Qualifications

• Kubernetes (K8s) for distributed workloads and cluster orchestration.

• Data lakehouse platforms (specifically Databricks and DABs).

• Familiarity with GPU-accelerated computing and HPC clusters.

• Experience with 3D/2D asset processing (geometry transformations, rendering pipelines).

• Located in or near one of our employee hubs — Bay Area, CA; Seattle, WA

Our Values

• Brain: We value intelligence and the pursuit of knowledge. Our team is composed of some of the brightest minds in the industry.

• Heart: We care deeply about our work, our users, and each other. Empathy and passion drive us forward.

• Gut: We trust our instincts and are not afraid to take bold risks. Innovation requires courage.

• Taste: We have a keen eye for quality and aesthetics. Our products are not just functional but also beautiful.

Why Join Meshy?

• Competitive salary, equity, and benefits package.

• Opportunity to work with a talented and passionate team at the forefront of AI and 3D technology.

• Flexible work environment, with options for remote and on-site work.
