🌳Prochain objectif ? Construire les 10 prochaines startups championnes de l’impact d’ici 2025.
At Prolong, we believe post-purchase will become one of the most strategic layers of retail.
Repairs, returns, warranties, maintenance and customer care are no longer operational back-office processes. They are becoming major drivers of customer loyalty, profitability and sustainability.
That’s why we’re building Prolong.
A configurable operating system allowing the world’s largest retailers to orchestrate every aspect of their post-purchase operations.
Over the last two years, we’ve built the foundations.
Today, we’re reaching product-market fit with demanding enterprise customers across luxury, fashion and premium retail.
The next challenge is very different. It’s no longer about proving the product. It’s about building a platform capable of supporting hundreds of enterprise customers without becoming exponentially more complex.
We are guided by strong values that shape both our product and our culture:
🫶 CARE — We care for each other, our work, and every single user.
🚀 AMBITIOUS — We challenge the status quo and build globally by default.
🤝 TRUST — We own our results and lead through reliability and excellence.
🧑🎓 FAST LEARNERS — We move fast, learn faster, and never stop improving.
Your mission is to make sure Prolong scales the delivery of new clients in a demanding enterprise software environment.
As we grow from dozens to hundreds of enterprise customers, every new customer should make our integration & deployment methodology and tooling smarter, not heavier. Every implementation should strengthen our delivery capabilities & speed, and enrich our library of on-the-shelf connectors. The objective is not simply to execute projects well and ensure client success & satisfaction. It’s to redesign how projects are delivered.
At the same time, you will help us build one of the key growth driver: partner-led scalability, where ISVs (Independent Software Vendors) as well as system integrators implement & deploy our platform autonomously to their own customers
Today, every enterprise customer brings unique business processes, legacy systems and operational constraints.Your role won’t be simply to connect systems. It should be to continuously find patterns that allow us to transform bespoke implementations and customer complexity into reusable platform capabilities.
This role requires tech seniority, client facing, autonomy, rigor, and ownership.
1.Deliver new clients
Together with the Deliver Manager
your are responsible to ensure the success client success and satisfaction during the project delivery phase
you contribute to the specification and implementation of configurations within our workflow engine, working alongside client teams from scoping through to deployment.
You design and develop robust, scalable connectors between Prolong and third-party systems (PIM, ERP, e-commerce, CRM, etc.).
You build and maintain our connectors & integrations public API to ensure accessibility by third party partners, quality, performance, configurability and maintainability
2.Ensure geographic expansion & upsell for existing clients
Together with the Customer Success Manager, you are responsible to ensure client success and satisfaction after the project delivery and during the client RUN by deploying geographical expansion, upselling new module and activating new integrations
You ensure configurations and integrations evolve over time
You contribute actively to solve bugs coming from our ticketing system or detected internally in order to stick to our SLA
3.Scale internal and partner led delivery
We believe implementation should progressively disappear as a bottleneck.
Today, projects are delivered. Tomorrow, projects are configured. Eventually, projects will largely be orchestrated through AI-assisted configuration.
Your mission is to redesign every layer of our delivery model so each new implementation becomes faster, simpler and more autonomous than the previous one.
You are responsible to redesign how projects are delivered for better quality, efficiency & autonomy of project team (internal & third parties). You do not limit to simply execute projects and continuously identify and deliver new ideas to improve our existing integration & deployment architecture, methodology and associated tooling, such as:
- Configuration over custom development
- Automation over manual work
- AI-assisted delivery wherever it creates value
You work closely with the Engineering & Platform director on initiatives to ensure scalability, security modularity & self-service for our clients and third party partners (modular architecture enhancement by design, full self-serve configuration layers, China-ready architecture & compliance)
4.Be the technical voice in pre-sales and sales engineering activities
You work closely with Sales and Sales Engineering team when answering to RFP (Request for proposal)
You are the technical voice during oral presentation linked to RFP oral defense or to advanced pre-sales meetings where we need to provide assurance regarding Security, Scalability and Architecture
Capture recurring customer requirements and continuously feed Product with insights that help evolve the platform.
Main landscape
Backend: NestJS, TypeScript, Prisma, PostgreSQL
Frontend: React, TypeScript
Infrastructure: Google Cloud Platform, Terraform, GitHub Actions
Integration landscape:
Our integration work spans a wide and varied range of protocols and systems — REST, SOAP, GraphQL, flat files, FTP, and more. You’ll connect everything from beautifully documented APIs (think Stripe) to battle-hardened legacy systems (think M3). If you take pride in making things work cleanly regardless of what’s on the other side of the wire, you’ll fit right in.
In terms of organization:
You will be managed by the Chief Operation Officer (COO) and mentored technically by our CTO
You will take parts to tech rituals in order to build expertise in the platform, our standards, and our tech culture
You’ll sit at the intersection of Product, Engineering, Operations and Sales.
Why Join Prolong?
You’ll join Prolong at one of the most exciting moments in its history.
Product-market fit is emerging.
Enterprise customers are arriving.
The next challenge isn’t building more features. It’s building the operating model that allows the platform to scale globally.
Few opportunities allow you to redesign how enterprise SaaS is deployed while AI is simultaneously reshaping software engineering. That’s exactly what you’ll build
We are offering:
A core role during a pivotal moment in our growth.
True ownership and impact — you’ll not only deliver new clients but shape the scale of our delivery
A stimulating environment with a strong product and tech culture.
A mission-driven company building for a more sustainable, circular future.
Remote-first culture: work from wherever you are most productive — with full-team on-site gatherings every 6 weeks to build strong connections, align on priorities, and enjoy time together.
Equipment of your choice, flexible hours.
The mindset we are looking for
someone who enjoys enterprise complexity.
Someone capable of understanding both business operations and software architecture.
someone who naturally challenges existing processes instead of accepting them.
someone who believes technology should continuously reduce operational effort.
Your profile:
You have 8+ years of experience in software development (fullstack with a strong backend focus), with at least one management experience and a proven track record in solution deployment & technical integration.
You are very comfortable in client facing context with both technical and business teams during the different client phases: pre-sales, project & run.
You are autonomous, reliable, organized, very hands-on technical deliveries and capable of taking ownership of complex topics end to end
You have a strong ability to leverage AI to gain productivity while ensuring quality of your technical deliveries
You demonstrate natural leadership and have the ambition, over time, to build and manage a small team.
Nice to have:
Previous experience in deploying at scale SaaS B2B Solution .
Experience with distributed systems, ETL pipelines, or middleware.
In 18 months, you’ll know you’ve succeeded if…
Enterprise implementations are significantly faster than today
Our delivery methodology has become a competitive advantage
Partners can deploy Prolong autonomously
Customers view implementation as a strength, not a project
Every implementation enriches the platform
AI has become part of every delivery workflow
We believe in keeping our process clear, respectful of your time, and focused on real collaboration.
