About

🌍 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 operate a highly technical, backend-driven platform (~90% of the product’s value) where:

  • Latency directly impacts revenue

  • Correctness is critical

  • Failure handling is part of everyday engineering

As a Backend Software Engineer, you’ll work at the very core of our platform:

  • Real-time inventory synchronisation

  • Order orchestration across multiple merchants

  • Distributed systems under strong consistency constraints

  • Integrations with complex external systems (ERP, OMS, WMS, marketplaces)

This role is for engineers who:

  • Enjoy real-world complexity

  • Want end-to-end ownership

  • Care about robustness, scalability, and business impact

🛠️ What You’ll Do

⚙️ Tech Stack

Rust · gRPC · PostgreSQL · AWS · Docker

🎯 Your Mission

As a Backend Software Engineer (Confirmed / Senior), you will:

  • Own complex backend features from design to production

  • Build systems that operate at scale in real, messy e-commerce environments

  • Continuously improve the platform based on production feedback

💪 Your Responsibilities

You will:

  • Design, build, and operate core backend services for:

    • Real-time inventory sharing
    • Order routing
    • Transactional workflows

  • Own features end-to-end: architecture, implementation, deployment, monitoring, iteration

  • Integrate with external systems (ERP, OMS, WMS, marketplaces), handling:

    • Heterogeneous data models
    • Partial failures
    • Operational constraints

  • Collaborate closely with Product & Operations to turn business problems into reliable technical solutions

  • Improve reliability, performance, and architecture, contributing to:

    • Incident analysis
    • Technical standards
    • Long-term platform roadmap

🤝 Who you’ll work with

  • A strong, product-oriented engineering team

  • Experienced founders and senior engineers who have already scaled complex systems

  • Daily collaboration with Product and Operations to ensure what we build actually works in production

✅ This is a deep engineering role, close to production and real business impact

🌟 Why this role is exciting

  • Backend engineering truly matters at Stockly

  • Few roles offer such a direct link between code and revenue

  • You’ll solve problems with no obvious solutions, under real constraints

  • Every improvement helps independent retailers compete with e-commerce giants

If you enjoy building systems that must be correct, resilient, and scalable, this role is for you.

📈 Your Growth at Stockly

  • You can grow by:

    • Deepening your technical expertise
    • Expanding your ownership scope
    • Becoming a key contributor to platform architecture

  • As Stockly scales, you’ll work on increasingly complex systems while staying hands-on

👉 At Stockly, you drive your own growth. The more you want to take ownership, the more room you’ll have.

Preferred Experience

✅ What will help you succeed

  • 2+ years of experience in backend or platform engineering (seniority is flexible - impact matters more than titles)

  • Strong coding skills in at least one backend language (Rust, C++, Go, Scala, Haskell, OCaml, etc.)

  • Willingness to learn Rust (you don’t need to be fluent on day one)

  • Solid understanding of:

    • APIs & databases
    • Performance & observability
    • Testing & production constraints

  • Ability to:

    • Turn ambiguous business needs into concrete technical solutions
    • Make pragmatic trade-offs between speed, scalability, and maintainability

  • Curious, rigorous, and eager to learn from incidents and edge cases

🚨 Please think twice before applying if…

  • You’re uncomfortable with complexity and uncertainty

  • You strongly prefer slow-moving, highly stable environments

  • You’re not comfortable working in English

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