Job description

The 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.
  • Demonstrated expertise designing and shipping highly scalable, resilient and cost-effective cloud-based backend solutions in production, not just in theory.
  • Strong experience with AWS cloud infrastructure, containerization (Docker/Kubernetes), and modern continuous deployment practices.
  • Demonstrated experience designing and implementing REST APIs. GraphQL APIs is a nice to have.
  • Experience with the stack we leverage in our platform, or equivalent:
    • Python
    • FastAPI, Strawberry
    • SQLAlchemy
    • Alembic
    • Postgres
  • Demonstrated experience working as part of a startup, owning outcomes end-to-end, moving fast with limited resources, and building scale before scale is guaranteed.
  • Demonstrated experience leveraging agentic coding tools such as Claude Code, Cursor or GitHub Copilot to meaningfully accelerate development velocity.
  • Strong instincts for data modeling and building systems that stay reliable under real-world production load.
  • Experience implementing and evolving infrastructure as code, e.g. with Terraform.
  • Experience with high-volume data ingestion pipelines, such as video, audio or streaming data (nice to have).
  • Experience with Test driven development methodology (nice to have).

Why join

  • The chance to build the platform that carries thousands of real-time video streams, serving live production lines at a real manufacturing scale.
  • Direct collaboration with our Head of Engineering and founders.
  • Real influence over the architecture, engineering standards, tooling, and how we use AI in our own development process.

Compensation & Benefits

  • Competitive salary and stock options
  • Competitive health benefits
  • Health and wellness spending account, from $500 to $1,000 annually
  • Latest MacBook and modern tooling
  • Opportunity to grow as the company scales


L'occasion

Le secteur manufacturier fait rouler l'économie mondiale, avec 50 000 milliards de dollars par année, et il repose largement sur la dextérité et le savoir-faire des gens pour produire les biens dont nous dépendons tous les jours. Pourtant, les manufacturiers ont peu de visibilité quand un problème survient aux postes d'assemblage manuel, ce qui nuit à la productivité et à la qualité.

Assembler AI change la donne.

Nous utilisons la vision par ordinateur et l'intelligence artificielle pour aider les manufacturiers à améliorer la qualité, à réduire le gaspillage, à augmenter la cadence de production et à permettre aux employés de plancher de donner leur pleine mesure.

Appuyés par Diagram Ventures, nous bâtissons une entreprise qui définit sa catégorie, à la croisée de l'IA, de la fabrication et de l'excellence opérationnelle.

Le poste

À titre de développeur logiciel backend senior, vous architecturerez, concevrez, construirez, déploierez, opérerez et ferez évoluer la plateforme backend qui transforme des milliers de flux vidéo en temps réel en informations exploitables immédiatement par les opérateurs et les ingénieurs. Vous travaillerez en étroite collaboration avec notre chef de l'ingénierie ainsi qu'avec notre équipe d'IA R&D afin d'architecturer la plateforme SaaS Operator Vision, de renforcer les services, les API et l'infrastructure. Vous êtes fier de bâtir et de livrer du code de grande qualité, hautement évolutif, à grande vélocité ? Ce poste est pour vous!

Ce que vous ferez

  • Participer à la définition de l'architecture de la plateforme, en travaillant étroitement avec le chef de l'ingénierie et en tenant compte des compromis qui nous permettront de passer du projet pilote à la production complète.
  • Concevoir et mettre en œuvre la plateforme backend infonuagique — services, API et pipelines de données — y compris les capacités d'auto-mise à l'échelle et de reprise après défaillance qui maintiennent la plateforme disponible pour les lignes de production en direct.
  • Contribuer à bâtir l'infrastructure qui ingère et traite des milliers de flux vidéo en temps réel, en travaillant étroitement avec l'équipe d'IA R&D.
  • Contribuer à définir et à mettre en place les conventions de développement — normes de code, pratiques de test et façon dont l'équipe utilise les outils de codage agentique pour aller plus vite sans couper les coins ronds.
  • Contribuer à bâtir les pipelines CI/CD et les pratiques de déploiement permettant à l'équipe de livrer rapidement, de manière sécuritaire et fréquemment.
  • Contribuer à l'exploitation du service — instrumentation des journaux, des métriques et des alertes, et participation à la réponse aux incidents lorsque les choses ne fonctionnent pas comme prévu.
  • Collaborer avec les équipes produit et IA R&D pour traduire les besoins des clients en solutions techniques.

Ce que nous recherchons

  • Ingénieur backend chevronné possédant une expertise approfondie et démontrée en Python ou dans un autre langage backend de haut niveau comme Go ou Rust, et à l'aise de travailler avec plusieurs langages et piles technologiques selon les besoins du problème.
  • Plus de 7 ans d'expérience professionnelle en développement logiciel backend.
  • Expertise démontrée dans la conception et la livraison de solutions backend infonuagiques hautement évolutives, résilientes et rentables en production, pas seulement en théorie.
  • Solide expérience avec l'infrastructure infonuagique AWS, la conteneurisation (Docker/Kubernetes) et les pratiques modernes de déploiement continu.
  • Expérience démontrée dans la conception et la mise en œuvre d'API REST. Les API GraphQL sont un atout.
  • Expérience avec la pile technologique que nous utilisons dans notre plateforme, ou l'équivalent :
    • Python
    • FastAPI, Strawberry
    • SQLAlchemy
    • Alembic
    • Postgres
  • Expérience démontrée dans un environnement de startup, avec la capacité de prendre en charge des résultats de bout en bout, d'avancer rapidement avec des ressources limitées et de bâtir pour l'échelle avant que l'échelle ne soit garantie.
  • Expérience démontrée dans l'utilisation d'outils de codage agentique comme Claude Code, Cursor ou GitHub Copilot afin d'accélérer significativement la vélocité de développement.
  • Excellents réflexes en modélisation de données et en conception de systèmes qui demeurent fiables sous une charge de production réelle.
  • Expérience dans la mise en œuvre et l'évolution de l'infrastructure comme code, p. ex. avec Terraform.
  • Expérience avec des pipelines d'ingestion de données à haut volume, comme la vidéo, l'audio ou les données en continu (un atout).
  • Expérience avec la méthodologie de développement piloté par les tests (un atout).

Pourquoi vous joindre à nous

  • La chance de bâtir la plateforme sur laquelle roulent des milliers de flux vidéo en temps réel, au service de lignes de production actives à l'échelle manufacturière réelle.
  • Une collaboration directe avec notre chef de l'ingénierie et les fondateurs.
  • Une influence réelle sur l'architecture, les normes d'ingénierie, l'outillage et la façon dont nous utilisons l'IA dans notre propre processus de développement.

Rémunération et avantages sociaux

  • Salaire concurrentiel et options d'achat d'actions
  • Assurance collective concurrentielle
  • Compte de dépenses santé et mieux-être, de 500 $ à 1 000 $ par année
  • MacBook récent et outils de travail modernes
  • Occasion de grandir avec l'entreprise
