Job Description
Job DescriptionThe Opportunity
Manufacturing powers the global economy at $50T a year and it relies heavily on human dexterity and skill to produce the goods we rely on every day. Yet manufacturers have little visibility when issues arise at manual assembly stations, impacting productivity and quality.
Assembler AI is changing that.
We use computer vision and artificial intelligence to help manufacturers improve quality, reduce waste, increase throughput, and enable frontline employees to perform at their best.
Backed by Diagram Ventures, we're building a category-defining company at the intersection of AI, manufacturing, and operational excellence.
The role
As a Senior Backend Software Developer, you'll architect, design, build, deploy, operate and scale the backend platform that turns thousands of real-time video feeds into insights operators and engineers can act on immediately. You'll work closely with our Head of Engineering as well as our AI R&D team to architect the Operator Vision SaaS platform, harden the services, APIs and infrastructure. You take pride in building and delivering high quality and highly scalable code with high velocity? This is for you!
What you'll do
- Participate in the platform's architecture definition, working closely with the Head of Engineering, and taking into consideration the tradeoffs that let us scale from pilot to full production.
- Design and implement the cloud-based backend platform — services, APIs and data pipelines — including auto-scaling and failover recovery capabilities that keep the platform available for live production lines.
- Contribute to building the infrastructure that ingests and processes thousands of real-time video streams, working closely with the AI R&D team.
- Contribute to defining and putting in place development conventions — code standards, testing practices, and how the team uses agentic coding tools to move faster without cutting corners.
- Contribute to building the CI/CD pipelines and deployment practices enabling the team to ship fast, safely and often.
- Contribute to operating the service — instrumenting logging, metrics and alerting, and taking part in incident response when things don't work as expected.
- Partner with product and AI R&D to translate customer needs into technical solutions.
What we're looking for
- Seasoned backend engineer with deep, demonstrated expertise in Python or another high-level backend language such as Go or Rust, and you're comfortable working across multiple languages and stacks as the problem demands.
- 7+ years of professional backend software development experience.
