Senior Full Stack Software Engineer

You're the first point of contact between Volta and enterprise accounts in France. Your mission: open qualified conversations with senior decision-makers (CEOs, commercial directors, operations leaders) at large B2B distributors, wholesalers, and brands (€100M+ revenue), run discovery conversations that qualify both fit and readiness, deliver product demonstrations that map to their stated pain, and hand off genuinely warm, well-prepared opportunities to our Account Executives.

This is not a volume game. You're hunting at enterprise scale, smaller target list, deeper engagement, higher-quality handoffs. You combine prospecting rigor with the ability to speak credibly about product and process.

Enterprise prospecting & sequencing

• Identify and prioritize target accounts aligned with Volta's ICP
• Build personalized multichannel sequences (LinkedIn, email, phone) tailored to each buyer persona and their operational challenges
• Move beyond initial contact: you know how to get past gatekeepers, overcome common objections, and advance conversations with C-level decision-makers

Discovery & ICP qualification

• Conduct 20–30 min discovery calls that qualify both pain and readiness for change
• Assess true enterprise fit: supply chain complexity, digitalization maturity, procurement process sophistication, budget awareness
• Ask diagnostic questions that uncover whether this account is truly a fit, not just whether they check demographic boxes
• Document decision-maker org, buying process, and timeline — not just pain points

Product demonstration

• Run 30-min product demos in discovery calls that showcase how Volta solves stated pain
• Demonstrate product knowledge: understand core features, typical use cases, and how to tailor the walkthrough to the prospect's situation
• Use the demo as a qualification tool: their engagement and questions tell you if they're ready to move forward

Account preparation for AE handoff

• Hand off opportunities with clear context: stakeholders identified, pain points mapped to features, process timeline understood, initial objections surfaced
• Prepare a brief for the AE: this is what they care about, this is who you'll be talking to, this is why they took the call
• Ensure the account is genuinely ready for AE engagement, not just "they said yes to a meeting"

CRM discipline & reporting

• Maintain rigorous activity tracking in HubSpot: call notes, discovery findings, sequence status, stage progression
• Report weekly: pipeline generated, discovery-to-qualified conversion rate, demo outcomes, feedback for continuous improvement
• Contribute to team KPIs: qualified opportunities per month, AE conversion rate, activity velocity

Messaging & learning

• Share field intelligence: what objections you're hearing, which angles work, which buyer personas engage, market signals
• Contribute to messaging refinement with the leadership team
• Continuously iterate on positioning based on what's landing with your accounts

Must have

• 2–3 years of prospecting experience
  — you've already successfully hunted at this scale or are ready to step up to it
• Demonstrable track record
  : you can show us qualified opportunities you personally generated, with pipeline metrics (reply rate, discovery-to-qualified ratio, what you consider "qualified")
• Senior decision-maker prospecting experience
  — you know how to engage C-level and Director-level buyers, not just influencers
• Proficiency with core tools
  : LinkedIn Sales Navigator, email sequencer (Lemlist, La Growth Machine, or similar), HubSpot
• Native French + excellent written communication
  — professional English for internal collaboration
• Product curiosity
  — you're comfortable learning product features on the fly and can speak credibly about how software solves operational problems
• Resilience + rigor
  — you thrive in a demanding environment, own your numbers, and treat discipline as competitive advantage

Nice to have

• Prior experience running product demos or presenting to senior stakeholders
• Account-based prospecting (ABM) methodology experience
• Domain knowledge in distribution, wholesale, supply chain, ERP, or B2B commerce
• Exposure to AI/automation and why it matters in B2B operations
• Track record of moving from SDR/BDR into more complex enterprise hunting roles

Chez Volta, nous croyons que la diversité rend nos équipes plus fortes. Toutes les candidatures sont les bienvenues, quels que soient le genre, l'origine ou le parcours.

About The Team
OpenAI’s Forward Deployed Engineering team partners with customers to turn research breakthroughs into production systems. We operate at the intersection of customer delivery and core platform development.

About The Role
Forward Deployed Engineers (FDEs) lead complex end-to-end deployments of frontier models in production alongside our most strategic customers. You will own discovery, technical scoping, system design, build, and production rollout, partnering directly with customer engineering and domain teams.

You will measure success through production adoption, measurable workflow impact, and eval-driven feedback that changes product and model roadmaps. You’ll work closely with our Product, Research, Partnerships, GRC, Security, and GTM teams.

This role is based in Paris. We use a hybrid work model of 3 days in the office per week. We offer relocation assistance. Travel up to 50% is required.

In this role you will

• Own technical delivery across multiple deployments from first prototype to stable production
• Build full-stack systems that deliver customer value and sharpen how we learn
• Embed closely with customer teams, understand their needs, and guide adoption of what you build
• Scope work, sequence delivery, and remove blockers early
• Make trade-offs between scope, speed, and quality; adjust plans to protect delivery
• Contribute directly in the code when progress or clarity depends on it
• Codify working patterns into tools, playbooks, or building blocks that others can use
• Share field feedback that helps Research and Product understand where the models succeed and where they can improve
• Keep teams moving through clarity and follow-through

You might thrive in this role if you

• Bring 5+ years of engineering or technical deployment experience that includes customer-facing work
• Have scoped and delivered complex systems in fast-moving or ambiguous environments
• Write and review production-grade code across frontend and backend using Python, JavaScript, or comparable stacks
• Have built or deployed systems powered by LLMs or generative models and understand how model behaviour affects product experience
• Simplify complexity and make fast, sound decisions under pressure
• Communicate clearly with engineers, product teams, and customer stakeholders
• Spot risks early and adjust without slowing down
• Model calm and judgment when the stakes are high

Licorne Society a été missionné par une startup/InsurTech en pleine croissance pour les aider à trouver leur Senior Full-Stack Developer.

Descriptif du poste
Le produit que nous construisons et mettons entre les mains des utilisateurs est la base de la proposition de valeur : offrir des parcours efficaces, transparents, et fiables lors de toutes les interactions avec le produit d’assurance, notamment lors de l’onboarding, et lors de la déclaration de sinistres.

En tant que senior full-stack developer, tes missions seront de :

• Développer de bout en bout les fonctionnalités dont tu aura la responsabilité, et coordonner leur lancement et leur suivi avec le produit et les stakeholders
• Utiliser ta vision technique pour identifier des opportunités et les partager avec le reste de l’entreprise
• Participer à l’évolution de la vision technique commune

Le fonctionnement de notre équipe
Les membres de l’équipe gèrent leurs sujets de bout en bout et s’intéressent à toutes les technologies de la stack.

Comme il n’est pas possible d’être expert dans tous les domaines, nous recourrons souvent au pair coding sur les parties sur lesquelles nous sommes le moins à l’aise. L’approche sur les sujets complexes est souvent discutée à plusieurs avant de commencer à coder.

Les développeurs, le product designer et le product manager co-conçoivent les fonctionnalités et l’UI. On privilégie les séances de travail en pair dev / design pour être sûr de bien se comprendre et imaginer les meilleurs solutions possibles, à travers plusieurs itérations qui convergent vers le produit final.

On saisit toutes les opportunités d’améliorer nos outils et on reste à la pointe. La productivité qui en découle nous permet de rester dans un cercle vertueux. Notre stack est aujourd’hui composée de MongoDB, full stack TypeScript, tRPC, React, Emotion et Vite. Nos dépendances sont en permanence à la dernière version disponible.

Stack technique
Notre stack technique privilégie la sécurité des types et l’efficacité avec TypeScript. Nous utilisons React, Emotion, TanStack Router, et tRPC pour gérer l’état et la communication frontend-backend avec une forte sécurité des types.

L’infrastructure repose sur Kubernetes (GKE), Terraform, et ArgoCD pour l’hébergement et l’automatisation des déploiements. Les tests sont gérés par Vitest, Playwright, et Cucumber, avec des environnements éphémères via GitHub Actions pour les revues de code.

Les évolutions futures viseront à améliorer l’expérience développeur, optimiser la qualité et passer à une approche multi-cloud pour plus de robustesse et réduire les coûts.

Ton travail au quotidien

• Investiguer et résoudre tout bug, crash, ou alerte qui se présenterait (politique zéro-bug)
• Planifier, développer et mettre en production des évolutions fonctionnelles
• Échanger avec notre Product Designer et notre Product Manager sur les aspects fonctionnels et UI du travail
• Proposer des évolutions des éléments de framework quand le besoin se fait sentir
• Faire évoluer notre UI Kit quand apparaît un nouveau composant ou une évolution
• Challenger les solutions proposées, avoir de nouvelles idées, faire preuve de créativité
• Avoir un comportement exemplaire et servir de modèle pour les futurs employés de l'entreprise : curiosité, humilité, recherche du feedback, créativité, engagement.

Profil recherché

• Tu es à l’aise avec JavaScript et Node.js, et connais l’écosystème (la maîtrise de Typescript est un plus)
• Tu as du recul sur les choix d’architecture, et sais raisonner dessus en fonction des objectifs business
• Tu es autonome, sais t’auto-motiver, et as la capacité à t’auto-former
• Tu t’intéresses aux autres équipes et as un fort intérêt pour le métier
• Tu sais émettre des critiques constructives et apporter ta propre vision quand cela est pertinent
• Tu es à la recherche de feedback dans un état d’esprit d’amélioration continue
• Rapidité et efficacité sur les tâches de développement backend classiques, comme fournir au frontend des APIs implémentant la logique métier, s’appuyer sur les structures de données classiques pour manipuler des données, organiser les données en base, évaluer, choisir, et utiliser des APIs tierces parties, implémenter des tâches de fond
• Maîtrise de HTML, CSS et React, ainsi que la capacité d’être force de proposition sur l’architecture du frontend
