Forward Deployed Software Engineer (Full-stack)

Permanent employee, Full-time · Germany Berlin, Barcelona, Spain

TL;DR

We’re hiring a Forward Deployed Full-Stack Engineer to work directly with our strategic customers. By embedding with their teams, you will design, build, and ship production-ready features, integrations, and workflows on top of deepset’s AI Platform. You’ll blend a product-engineering mindset with customer-facing technical depth: crafting intuitive UIs, reliable backend services, and integration patterns that accelerate AI adoption. If you love solving complex product challenges hands-on and want to see your work deliver immediate, real-world impact, this role is for you.

Why deepset

At deepset, we’re on a mission to make custom AI solutions accessible to every organization. With Haystack, thousands of developers build advanced LLM applications every day, while our enterprise-ready AI Platform helps companies turn large language models into business value. We’re remote-first, flexible, and built on a culture of trust and ownership. You’ll collaborate with top-tier tech talent, tackle meaningful challenges, and help transform complex AI into solutions that are simple, powerful, and ready for the real world.

What you will do

Design & Land

Own technical outcomes from POC → production: frontend workflows, backend services, customer-specific integrations, and feature extensions.
Build intuitive React/TypeScript UIs and robust backend logic in Python that enable enterprises to orchestrate large-scale LLM applications.
Produce reference architectures, reusable UI components, and integration templates; upstream productizable improvements to Product & Engineering.
Unblock enterprise environments by defining API requirements, designing data flows, aligning on authentication models (e.g., OIDC/SAML), and integrating with customer systems.
Drive clarity from ambiguity: translate customer needs into well-scoped product solutions and deliver fast time-to-first-value.

Run & Harden

Define success metrics with customers: usability expectations, performance constraints, data consistency guarantees, and UX quality standards.
Implement testing, monitoring, and lightweight observability for customer-facing workflows you build.
Support planned releases, customer rollout coordination, and backward-compatibility validation to ensure smooth upgrades.

Partner & Enable

Work closely with users, product managers, designers, and engineers to deeply understand customer workflows and shape intuitive end-to-end experiences.
Train customer teams on the features you deliver—UI concepts, APIs, customization hooks, and troubleshooting paths.
Prioritize “productization opportunities” with Product/Engineering based on real-world usage and field signal.
Document clearly: setup guides, UX flows, API examples, best practices, and “golden path” usage patterns.
Handle urgent customer-facing issues during high-priority deployments or escalations

Requirements

7+ years of professional experience in Full-Stack Engineering, Solutions Engineering, or Forward-Deployed/Customer-Facing Engineering roles.
Strong proficiency in JavaScript/TypeScript, React, and backend development in Python.
Solid mastery of:
- REST APIs, data modeling, and SQL databases
- CI/CD pipelines, testing strategies, and production-grade coding standards
- Containerized environments (e.g., Docker; Kubernetes familiarity is a plus but not a core requirement)
Evidence of shipping customer-facing features and operating production systems.
Experience integrating with enterprise systems (authentication, APIs, security/compliance requirements).
Excellent communicator who is comfortable working with customer executives and engineering teams under time pressure.
Must be a resident of the European Union with an EU passport.
