Job Description

Deine Rolle

Customer Discovery & Solution Design

• Work directly with customers to understand their IT landscape, data flows, operational processes, and integration requirements
• Design robust integration concepts —across third-party systems, APIs, EDI formats, file-based exchanges, and customer-specific workflows
• Translate customer requirements into clear technical specifications, implementation plans, and handover materials for engineering

Hands-on Implementation

• Build, configure, or prototype integration components as needed
• Work closely with engineering to bring scalable solutions into production
• Leverage AI tools (Copilot, Claude, Cursor) strategically to deliver faster

Documentation & Repeatability

• Write excellent documentation —for both customers and our team
• Build reusable integration patterns and playbooks that make future onboarding faster and more self-service-friendly

Adoption & Customer Success

• Take ownership of integration success even after go-live—monitor usage, gather feedback, iterate with customers, and drive adoption
• Serve as a bridge to Customer Success and Sales – provide technical pre-sales support, demos, and spec reviews

Your mission

You are the bridge between our clients and our engineering team When a client wants to connect to Vestigas, you own the process from the initial technical discovery through to a successful go-live—and beyond.
You understand the customer’s IT landscape, design the appropriate integration, write clear technical specifications, build prototypes yourself, and work closely with Engineering to get the integration up and running. You then ensure that it is actually being used.
With every integration, you continue to expand our playbooks and self-service components —so that the next integration goes faster than the last.

Your profile

Must-Haves:

• 3+ years of experience in a customer-facing technical role (Solutions Engineer, Integration Engineer, Sales Engineer, Technical Consultant, Implementation Engineer)
• Hands-on experience with APIs, webhooks, data formats, and system-to-system communication
• Experience with integration formats: EDIFACT, XML, ZUGFeRD, ebInterface, CSV, JSON, REST/SOAP – at least one of these with real depth
• Prototype-level coding skills (Python preferred) – you can build, not just explain
• Clear specification and documentation writing skills – you communicate effectively with engineers AND with client IT teams
• Cross-functional experience with Customer Success, Backend, Frontend, Product, and external providers
• Fluent in German and English

Nice-to-have:

• ERP system experience: SAP, Datev, Microsoft Dynamics, Sage
• Experience in the construction industry, logistics, supply chain, or other traditional B2B industries
• Pre-sales experience (technical demos, RFPs, proposals)
• Experience with integration platforms (Workato, Mulesoft, Zapier, n8n)
• Python stack experience (FastAPI, Pydantic)
• Startup or scale-up experience

Why us?

• A hybrid role for tech professionals who want more than just coding —customer interaction, solution design, and hands-on implementation all in one role
• You’ll build a function that doesn’t yet exist —playbooks, self-service tools, and integration standards will be created alongside you
• Direct business impact – every integration you launch translates to measurable revenue; Sales and CS see your work every day
• Real customer problems – you’ll work with IT teams at Germany’s largest construction firms
• Top clients – 14 of Germany’s top 20 construction firms + 17 of Germany’s top 20 suppliers
• Modern tech stack – Python/FastAPI, AWS, AI-first workflows
• Construction Site Visits – you see where your integrations actually end up (construction site ≠ theory)
• Hybrid with flexibility – a mix of office, remote, and on-site client work
• Flexible career path – opportunities to move toward Solutions Lead, Pre-Sales Engineering, Customer Success Engineering, or back toward Core Engineering
• Includes gym membership, team events, flat hierarchies
