About
REELIANT designs, modernizes and maintains critical digital systems, with a central requirement: trust over time.
Our craft
Evolve critical systems without operational disruption.
Architect, integrate and ship services that hold the load and integrate cleanly into the existing stack.
Pilot the run: monitoring, security, compliance, technical debt — over the long term.
Our team
Architects, Lead Devs, Developers, Product Owners, DevOps: we design and operate critical systems. Java stack, JavaScript ecosystem, hosting in France, application security — our technical choices are driven by robustness, not trends.
We hire sharp profiles who share our obsession with clean code and work done right.
Our values
Quality is not a negotiable option. We apply absolute rigour on every line of code, because we know the durability of a critical system is decided at design time.
We are not mere service providers. We take responsibility for the full lifecycle of your systems, from delivery through operational maintenance over time.
No hype, only robust solutions. Our technology choices are driven by field experience and the will to build software that is reliable, secure, and scalable over ten years.
Recognition
Responsibility · CSR
Innovation · R&D
The Innovation Tax Credit (CII) is awarded by the French government to companies that invest in designing innovative products or services. REELIANT is recognised under this scheme for its work in software architecture, critical systems integration, and applied AI.
REEL(IA)NT by design
AI is not a black box at REELIANT. We build systems where it remains a piloted, auditable, predictable component. No off-the-shelf miracles: just serious engineering, from sketch to production.
AI remains a component you control, not a black box. Every decision is traceable and explainable.
Your data never leaves your secure perimeter. RAG architecture, hosting in France, zero public training.
We choose the right lever (LLM, RAG, predictive) for your context, and we monitor what it produces in real conditions.
AI powers our own workshop, so we can focus on what matters: architecture, security, rigorous testing.
The Workshop
A team of developers, architects and engineers who make rigor a culture, not a constraint.
Senior team · average 12+ years of experience, 9 years on average at Reeliant
Co-founder & Co-CEO
24 years of experience · co-founder« Our final validation test is simple: would we be proud to use this tool ourselves? If the answer is no, we don't ship. »
Co-founder & Co-CEO
23 years of experience · co-founder« SI maturity determines AI relevance. On readable systems, AI is a real lever. On opaque systems, it mostly amplifies the confusion. »
DevOps & Security Lead
23 years of experience · 9 at Reeliant« In critical systems, the unexpected is a risk you reduce through repeatability. DevOps is the tool that ensures every deployment is a non-event. »
Software Engineering Lead
19 years of experience · 9 at Reeliant« You don't build software for today. You build it for three years from now. »
Technical Project Director
15 years of experience · 9 at Reeliant« Between the brief and production, there's everything we anticipated. »
Technical Project Director
12 years of experience · 9 at Reeliant« A successful technical project starts with a team that speaks the same language as its client. »
What convinced me to join REELIANT was the rigor. No technical debt accepted out of laziness, no shortcut justified by the sprint.
Full-stack dev, 2 years at REELIANT
We work on systems that have real impact. Every line of code matters — and that changes everything about how we work.

Join the Workshop
Four open positions. Critical systems, demanding clients, a team that does what it says. No Kafkaesque process: you apply, we respond within 48 hours.
You build and operate infrastructure for systems that can't afford downtime. No bureaucracy: documented technical choices, measured responsibilities, a scope that grows with trust.
You take ownership of architecture and development of high-demand applications: performance, security, maintainability. You lead technically without creating bureaucracy.
You define the architecture of our clients' systems: digital identity, applied AI, critical IS modernization. You translate business or regulatory requirements into grounded technical decisions.
You lead technology projects in a context where AI is changing the rules. You understand concretely what that means for a backlog, an estimate, a client relationship. You bring structure without overhead.
Your profile doesn't match exactly but you recognise yourself in our approach? Spontaneous application.
A 30-minute conversation is enough to understand your context and see if we're the right partners for your critical systems.
