About

Stockly in a Nutshell

🌍 Our mission

🔭 Stockly, a French Tech 120 company, is a tech-retail company solving the supply/demand mismatch in e-commerce.

  • With our technology, we connect in real-time e-commerce websites in need for stock with the inventory of hundreds of other retailers who have the same products available, and who can fulfill the order on their behalf.

  • E-retailers can keep selling products that are out-of-stock, while others can gain additional sales, in a seamless experience for the end-consumer.

🏆 Our mission is to create the world’s 1st globally shared inventory for e-commerce. To better understand what we do, check out our french pitch at BFMTV (🇫🇷), or our pitch at Techstars back in the days (🇬🇧).

📖 Our story

  • Stockly was founded in 2018 by Eliott Jabès & Oscar Walter (Telecom and ENS graduates) to tackle one of e-commerce’s biggest problems: lost revenue due to stock-outs.

  • Today, Stockly operates a network connecting hundreds of retailers across Europe, processing millions of e-commerce orders every year.

  • In early 2025, we raised €26M in Series B, a funding round led by 83North, alongside Eurazeo, Daphni, Anyma Capital and existing investors, to accelerate our European expansion and scale our platform.

👥 Our team

  • A team of 100+ builders, based in Paris.

  • Strong engineering culture.

  • A culture built on ownership, initiative, and impact.

  • You won’t just “execute tasks”: you’ll contribute shaping the future of e-commerce infrastructure.

Job Description

🔥 Why Stockly needs you

Stockly is not a typical SaaS product. We run a highly technical, backend product where:

  • Reliability is non-negotiable

  • Build and deployment correctness directly impact production

  • Scale, determinism, and reproducibility matter every day

As our DevOps Engineer, you will work at the foundation of everything we ship:

  • Developer environments and tooling

  • Infrastructure reliability and operability

  • The bridge between engineering velocity and production safety

🛠️ What you’ll do

⚙️ Tech stack: Bazel · Nix · Rust · AWS · Docker

Experience with Bazel is ideal. If not, strong experience with Nix + Rust and an appetite for build systems is a great alternative.

🎯 Your mission

As a DevOps Engineer, your mission is to:

  • Make our CI builds fast, deterministic, and reliable

  • Ensure developer environments are reproducible and easy to onboard

  • Build infrastructure and tooling that scales with the company

  • Raise the overall engineering bar by improving reliability and operability

You’ll work close to production, close to engineers, and close to real constraints.

💪 Your responsibilities

  1. Design, maintain, and evolve our build & CI systems, including:

* Bazel-based builds and tests, including:

* Build caching (we have ~1k services & 2M lignes of code)

* Artifact management

* Fast and reliable CI/CD pipelines

* Complex AWS integration & architecturing

  1. Own developer environments and tooling, ensuring:

* Reproducibility across machines and environments

* Fast onboarding for new engineers

* Efficient toolings for engineers

  1. Continuously improve reliability, observability, and operability, contributing to:

* Incident analysis

* Technical standards

* Long-term platform and infra roadmap

🤝 Who you’ll work with

  • A strong engineering team who cares deeply about technical excellence

  • Backend engineers building complex distributed systems in Rust

  • A team that values ownership, pragmatism, and impact over titles

🌟 Why this role is exciting

  • You’ll work on hard, foundational problems most companies postpone

  • Your work directly impacts:

    • Developer velocity
    • Production reliability
    • The company’s ability to scale

  • You’ll help build a product where:

    • Builds are predictable
    • Environments are reproducible
    • Engineers can focus on product, not tooling pain

If you enjoy building strong technical foundations that others rely on every day, this role is for you.

📈 Your growth at Stockly

  • You can grow by:

    • Becoming a key owner of our platform and infra architecture
    • Deepening expertise in build systems, tooling, and reliability
    • Expanding your scope as the company scales

  • You’ll stay hands-on, even as responsibilities grow

👉 At Stockly, ownership drives growth.

Preferred Experience

✅ What will help you succeed

  • 2+ years of experience in DevOps, Platform, or Infrastructure engineering (seniority is flexible — impact matters more than titles)

  • Strong experience with at least one of the following paths:

    • Bazel (build systems, CI, caching, monorepos)
    • or Nix + Rust, with a strong interest in build and infra tooling

  • Solid understanding of:

    • CI/CD systems
    • Linux & containers
    • Cloud infrastructure

  • Curious, rigorous, and comfortable working with low-level or non-glamorous problems

🚨 Please think twice before applying if…

  • You prefer purely product or feature-oriented roles

  • You dislike build systems, infra tooling, or debugging complex pipelines

  • You strongly prefer slow-moving, highly standardised environments

  • You’re looking for a fully remote role (we are office-first, with flexibility after ramp-up)
