  • Build and maintain ETL pipelines that turn raw scan, telemetry, and production data into something models can actually learn from

  • Design, build, and maintain ML models and pipelines that solve real production and product problems

  • Own the full lifecycle: data acquisition, feature engineering, training, deployment, monitoring, and iteration

  • Integrate models into our software and production systems — they have to work in the real world, not just in notebooks

  • Run experiments, evaluate honestly, and know when a model is good enough vs. when it isn't

  • Collaborate with software engineers, hardware engineers, and product teams to translate ambiguous problems into ML solutions (and to recognize when ML isn't the right tool)

  • Stay current with the field without chasing every new paper

    • ]]>     Your profile

  • Proven experience as an ML/AI Engineer, with models you've actually shipped to production

  • Strong Python and fluency with the standard data/ML stack (NumPy, Pandas, scikit-learn)

  • Solid ETL experience — designing and maintaining pipelines that handle real-world messy data at scale

  • Hands-on deep learning experience with PyTorch and/or TensorFlow

  • Solid grounding in ML fundamentals — you can explain why a model is failing, not just retrain it with different hyperparameters

  • Software engineering discipline: clean code, version control, testing, and the ability to operate models you've built

As our Backend Developer, you'll design and maintain the systems that power everything — from foot scanning and production to the consumer experience. You'll write clean, scalable code, contribute to architecture decisions, and help raise the bar for quality and security across our backend infrastructure.]]> What you'll do

  • Design and maintain the REST and GraphQL APIs that power scanning, production, and the customer-facing product

  • Own services end-to-end: schema design, performance, observability, and the on-call reality that comes with live systems

  • Shape architecture decisions as we evolve between monolith and selectively extracted services

  • Build async pipelines and queue-based workflows that move data between hardware, production, and customers

  • Write code that's tested at the unit, integration, and end-to-end level — and review code with the same standard

  • Mentor teammates and raise the bar on security, performance, and GDPR-conscious design

  • Collaborate closely with frontend, DevOps, hardware, and product

    • ]]>     Your profile

  • Strong PHP and Laravel experience, including Laravel Nova for internal tooling

  • Solid grasp of REST and GraphQL API design, plus authentication patterns (JWT, OAuth)

  • Comfortable with Docker, Git/GitLab, and CI/CD as part of your normal workflow

  • Practical experience with caching, queues, and async processing

  • Judgment about when to reach for a microservice and when not to

  • A security mindset and the discipline to apply it consistently


    • Nice to have


    • Python or Go (we use both in adjacent systems)

    • AWS experience

    • Background in data flow modeling or systems where backend meets hardware/IoT


    Why Laravel, in case you're wondering

    It's a fair question for a company doing what we do. Laravel lets a small team move quickly across a wide surface area admin tooling, customer APIs, internal services without fragmenting the stack. Where we need different tools (Python for ML-adjacent work, Go for performance-critical paths), we use them. The backend is pragmatic, not dogmatic.

As a part of our development team, you will find solutions for problems you never heard of and extend your knowledge daily.

    ]]>     What you'll do

  • Drive frontend architecture across our three product surfaces, making decisions about patterns, boundaries, and shared infrastructure that hold up over time

  • Own features end-to-end: from the design conversation through implementation, production rollout, and the inevitable debugging session when something behaves differently on the factory floor than it did in staging

  • Lead on performance, scalability, and observability. Core Web Vitals on the consumer side, realtime responsiveness on the hardware-adjacent side, and the instrumentation that lets us know which is broken

  • Apply frontend security rigor. Not just "we use auth tokens," but a working understanding of XSS, CSRF, CSP, dependency risk, and the everyday vulnerabilities that ship to production when nobody's watching

  • Navigate ambiguity: translate vague product, hardware, or operational needs into technical direction, and know when to ship a fast solution versus invest in a durable one

  • Collaborate directly with hardware engineers on the production-side UIs and with operations on scanning and in-store experiences. The feedback loop is short and the requirements are real

  • Mentor other frontend developers, review code with intent, and help establish the engineering practices that scale with the team

    • ]]>     Your profile

  • Senior-level React and TypeScript experience, with a track record of owning non-trivial frontend systems in production

  • Demonstrated ability to make architectural decisions about patterns, abstractions, and where to draw the line between shared and bespoke

  • Production debugging experience across the full path: browser, API contract, network, and infrastructure. You've been the person who actually found the problem

  • Performance and scalability work on real systems. Not just Lighthouse scores, but render performance, bundle discipline, data-fetching strategy, and caching

  • Frontend security awareness beyond auth-token plumbing. You understand the common attack surface and how to avoid expanding it

  • Comfort with ambiguity and the judgment to make decisions when requirements aren't fully formed


    • Nice to have

    • Experience with realtime, hardware-adjacent, or kiosk/in-store frontends

    • Manufacturing, production, or operational-tooling context

    • PWA and/or native (React Native, Capacitor) experience

    • Background contributing to design systems or frontend platform work

  • Own product and platform flows end-to-end: design, build, ship, operate, and improve. Not "frontend with backend tickets," and not "backend with React on the side." Real ownership across both sides of the API

  • Drive architectural decisions that span the stack: where logic lives, how data flows, how systems stay coherent as they grow

  • Operate production systems. Debug across browser, API, queue, database, and infrastructure, and improve observability so the next person doesn't have to start from scratch

  • Lead on performance and scalability on both sides: frontend render performance, bundle and asset strategy, backend query and queue performance, caching, async processing

  • Apply real security awareness across the stack: authentication and authorization done correctly, common exploits avoided by design (injection, SSRF, broken access control, XSS, CSRF), and dependency hygiene

  • Navigate the everyday tradeoff between shipping fast and building sustainable systems, and explain your reasoning to people who aren't engineers

  • Collaborate directly with hardware engineers on production-side workflows, and with operations on scanning and consumer-facing flows

  • Mentor other engineers and help establish the practices (reviews, testing, deployment, on-call) that scale with the team

  • Demonstrated architectural judgment across the stack: knowing where to put logic, when to introduce abstractions, when to extract a service

  • Production operations experience: debugging real incidents end-to-end across browser, API, queue, database, and infrastructure

  • Performance and scalability work on both sides, on systems with real load

  • Security awareness beyond basic auth. You understand the common attack surface and design to avoid it

  • Comfort with ambiguity and the ability to drive technical direction independently



    • Big advantage

    • Laravel, Laravel Nova, and PHP — this is our primary backend stack, and full-stack here genuinely means full-stack

    • Tailwind CSS

    • Docker as part of normal development and deployment

As our On-Premises DevOps Engineer, you'll bridge development and operations, automating workflows, hardening our systems, and ensuring the reliability our production environment depends on. From network security to CI/CD pipelines, you'll own the full infrastructure stack and play a critical role in building the factory of tomorrow.]]> What you'll do

  • Design, implement, and maintain our network infrastructure, including firewall configuration and segmentation

  • Run and evolve our virtualization and containerization platforms (Proxmox, Docker, Docker Swarm)

  • Build and maintain CI/CD pipelines that deliver software reliably to production

  • Apply Infrastructure as Code practices so our environment is reproducible, auditable, and recoverable

  • Administer Linux servers — security, performance, availability, and the unglamorous work that keeps them healthy

  • Configure reverse proxies, manage NAS systems, and own the storage and traffic layers

  • Implement logging, monitoring, and alerting so we know about problems before our colleagues do

  • Provide infrastructure support across all tiers — you're the person teams come to when something breaks

  • Collaborate with developers to make systems more reliable, observable, and easier to operate

  • Document the stack so it's not all in one person's head

    • ]]>     Your profile

  • Strong Linux server administration (Ubuntu in our case), including security hardening

  • Real network experience: Fortinet firewalls, TCP/IP, VLANs, switching (we use AOS-CX)

  • Virtualization and containers: Proxmox, Docker, Docker Swarm

  • Infrastructure as Code with Ansible and/or Terraform

  • CI/CD pipeline experience, especially GitLab CI/CD and Github Actions

  • Comfortable with reverse proxy configuration (Nginx, Traefik)

  • Monitoring and observability across the stack (Zabbix, Grafana, Prometheus, Elastic Stack)

  • The temperament for on-prem work — methodical, security-minded, and calm when production hardware is involved

    • Nice to have:

    • NAS administration, particularly TrueNAS

    • Experience supporting production or manufacturing environments

    • Background bridging IT and OT (operational technology) in a hardware-adjacent setting
