About algo1: algo1 is a VC-backed stealth-mode company building behavioural AI solutions for the retail industry. Our platform is designed from the ground up, no legacy, no patchwork systems, just a clean slate and a clear vision. Our mission is to bring the intelligence of modern machine learning directly to the in-store shopping experience.

The Role: As a Staff Engineer, you’ll work at the intersection of Product, ML, and Engineering to design and build the retail stack of the future. You'll be building user experiences on top of a platform that combines AI driven content delivery on autonomous edge devices on an IoT network, combined with the backend infrastructure of a cutting edge adTech platform. This isn't a staff role where you 'work across the stack', you'll be an integral part of defining the stack.

What You Will Own:

  • System Architecture: Design and lead the implementation of distributed, event-driven services that bridge the gap between cloud intelligence and edge devices.
  • Technical Strategy: Set the standards for service boundaries, data ownership, and system observability to ensure we scale seamlessly from 1 to 1,000+ locations.
  • AI Integration: Architect the orchestration layer for LLM-driven agentic workflows, moving beyond simple API calls to deeply integrated, autonomous system behaviours.
  • Mentorship & Culture: Continuously raise the bar for engineering excellence. Conduct deep design reviews, mentor mid-level engineers, and champion a culture of 'building with AI' and the use of autonomous development agents to accelerate our velocity.

Essential Qualifications:

  • Track Record: 8+ years of experience, with recent years spent in a Staff, Lead, or Principal capacity at a high-growth startup or a sophisticated scale-up.
  • Full-Stack Mastery: Expert-level proficiency in modern backends (Python, Go, or Java) and high-performance frontends (React/TypeScript).
  • Real-time Protocols: Mastery of async real-time, bi-directional communication protocols and patterns whether that's (WebSockets, SSE) for low-latency, real-time user experiences.
  • 'AI-First' Mindset: With AI tools, you have optimised your entire workflow around and can teach others to do the same.

Nice to Have:

  • Edge & IoT: Experience with 'Cloud-to-Edge' orchestration and managing state across geographically distributed systems.
  • Containerised Workloads: High comfort level with Kubernetes and container orchestration in a CI/CD-heavy environment.
  • Distributed Systems: Experience designing and operating event-driven architectures at scale (e.g., Kafka, Pulsar, or MQTT).
  • Domain Expertise: Prior exposure to the complexities of large scale retailTech, adTech, or marTech platforms.

If you’re excited by the idea of shaping the future of retail and eager to make a real impact from day one, we’d love to hear from you.

How to prepare for a job interview at algo1

Brush Up on Your Coding Skills

For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.

Know Your Tools and Frameworks

Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If algo1 uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Showcase Your Projects

Bring along a portfolio that highlights our best work. This could be code samples, GitHub repositories, or any side projects we’ve built. Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.

Prepare for Behavioural Questions

While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
