Observability, Performance & Operational Excellence

You will:

• Instrument services with logs, tracing, and metrics to ensure strong production visibility and fast iteration.
• Help define and uphold quality standards around latency, failure handling, cost efficiency, and resilience.
• Contribute to a strong "you build it, you run it" culture, where backend engineers own what they ship in production.
• Ensure AI-related services are built with secure coding and responsible data handling practices.

Cross-Functional Collaboration

You will:

• Collaborate with Product Managers and Designers to turn AI product concepts into concrete backend capabilities.
• Partner with applicative squads to connect backend services with the tools, context, and business actions needed by AI systems.
• Help create shared engineering knowledge around LLM integration, async workflows, and reliable AI feature delivery.

What We’re Looking For

Experience & Background

You have:

• Significant experience in backend software engineering in production environments
• A strong track record of designing and shipping scalable backend services with clear ownership of reliability and maintainability
• Experience contributing to complex technical projects in fast-paced product organizations
• Ideally, hands-on exposure to AI-enabled or LLM-backed product features in production

Technical & Data Skills

You have:

• Strong backend engineering skills with TypeScript/Node.js or adjacent technologies
• Good fluency in service design, asynchronous architectures, and resilient distributed systems
• Experience integrating APIs and external services into robust product backends
• Practical experience or a strong interest in integrating LLMs into production systems, ideally using platforms such as AWS Bedrock, OpenAI, or Anthropic
• Familiarity with technologies like Kafka, SQS, Step Functions, PostgreSQL, and modern observability practices

Leadership & Collaboration

You are:

• Highly autonomous and comfortable owning ambiguous technical problems from framing to delivery
• Able to work effectively in partnership with a Staff Engineer while independently delivering complex components
• Product-minded, customer-focused, and capable of translating business needs into backend systems
• Curious about AI-native product design and motivated by building durable foundations, not just short-term demos
• Fluent in written and spoken English, our business language

Nice to Have

• Experience with conversational or agentic systems
• Experience integrating LLMs with tool-calling, guardrails, and evaluation loops
• Experience with rich content processing, document workflows, or multimodal service design
• Experience in SaaS, fintech, or regulated environments

"Not ticking every box? We’d still love to hear from you. At Spendesk, we value skills, potential, and diverse experiences. If this role excites you and you believe you could contribute, we encourage you to apply."

How We Work

• AI-first, product-led: prototype fast, dogfooding, iterate based on data
• You build it, you run it: owning deployment, monitoring, and continuous improvements
• Collaboration by default: PM, Design, ML Engineering, and Backend Engineering work together toward outcomes
• Pragmatic engineering: we optimize for impact, not theoretical perfection

What Success Looks Like in Your First 90 Days

• You’ve shipped or materially advanced a production-grade backend component that supports conversational or agentic AI experiences at Spendesk.
• You’ve partnered effectively with the IC5 Staff Engineer to turn architectural direction into reliable, reusable backend services.
• You’ve integrated at least one LLM-backed capability through AWS Bedrock with appropriate observability, retries, and operational safeguards in place.
• You’ve improved one shared engineering capability—for example, orchestration patterns, service contracts, or cost/reliability monitoring— that can be reused by future AI features.

Location and Ways of Working

We value regular in-person collaboration. We’re primarily hiring in Paris, London, or Barcelona with a flexible hybrid setup. Outstanding remote candidates may be considered, but this is not a remote-first role.

Hiring Process

• HR screening call
• Discussion with the Hiring Manager
• Technical interview (live coding and/or system design depending on profile)
• Final interview with leadershi**

Application and CV Submission

As we are an international team, please submit your application and CV in English.
