Conxai Technologies GmbH

<div>About CONXAI 
CONXAI has built a no-code, agentic AI platform for the Architecture, Engineering and Construction (AEC) and physical industries, focused on knowledge-automation. We automate high-stakes, knowledge-intensive workflows traditionally trapped in siloed data, fragmented tools and tacit (undocumented) human expertise.

Senior Backend Engineer (Golang) - Munich

recup

<div><h4 class="jobSectionHeader">DEINE MISSION</h4>
We're building the next-generation backend that powers Germany's largest reusable-packaging network - a circular-economy deposit-return system live across 17,000+ locations. It's a two-track hybrid modernisation (brown and greenfield), cloud-native, event-driven TypeScript platform that runs real-world operational logistics: partners, point-of-sale, returns, billing, and fulfillment at national scale, expanding internationally. 
 
You'll join as a (senior) engineer (all genders) with real ownership: designing, building and own core services and working directly with our technical lead and peers on architecture. This is not a ticket-taking role - you'll shape the system, not just implement against it. 
 
What you'll do: 
<ul><li>
Design, build and own core platform services: partner management, point-of-sale, billing and invoicing, returns, fulfillment, and contract management</li><li>
Build event-driven, async-heavy integrations between services and external systems -outbox patterns, queues, retries, dead-letter handling</li><li>
Help drive our international expansion</li><li>
Partner with the technical lead on architectural decisions, data modelling, and the incremental extraction of capabilities from our existing platform into the new one</li><li>
Set the engineering bar-testing, observability, and operational readiness baked in from day one</li></ul> 
Our stack:<ul><li>
Language: PHP (7.1) (current),TypeScript (Nextdirection)</li><li>
Framework: Shopware 5.3 and NestJS</li><li>
Data: Mariadb, PostgreSQL + Prisma</li><li>
Cloud: Google CloudPlatform - Cloud Run, Pub/Sub, Cloud Tasks</li><li>
AI: Claude (Code, Chat and Cowork)</li><li>
APIs: REST</li><li>
Platform: GCP</li><li>
Existing platform (you'll learn its domain): PHP / Shopware the current production system we're incrementally extracting from.</li></ul><h4 class="jobSectionHeader">
WAS DU MITBRINGST</h4><ul><li>
7&ndash;10 years of backend engineering, with deep production experience in Node.js, TypeScript and substantial hands-on NestJS in production plus ability to work with legacy PP2 (PHP) code</li><li>
Strong system design and execution - you've designed distributed, async/queue-heavy systems and shipped them, not just white-boarded them</li><li>
Solid relational data modelling and SQL (MySQL, PostgreSQL ideally)</li><li>
Comfortable owning a problem end-to-end: design, build, test, ship, operate</li>
Munich-based. This is a hybrid role: 2 days/week in our Munich office, rest remote 
<li>
</li></ul>
Working with AI coding agents (a real part of this role) 
 
We use AI coding agents (Claude Code) every day as a core part of how we build. We expect you to as well. Concretely, we're looking for someone who: 
<ul><li>
has shipped production code with an AI coding agent,</li><li>
can describe their workflow - how they spec, prompt, review, and integrate agent output,</li><li>
has informed opinions on where agents fail and how they guard against it (review discipline, tests, architectural guardrails)</li></ul>
This isn't a buzzword for us - it's how the team works, and our hiring process reflects it (below).

How we hire<ul><li>
First Interview with People &amp; Organisation (~25 minutes) - We want to get to know you better in a first meeting and you will get to know RECUP's culture, values and vision and understand yourself better for a mutual fit</li><li>
Meet Hiring Manager (Tech Leader) (~25 minutes) - Understand the RECUP platform from a technical perspective</li><li>
Our take-home case (~55 minutes) is AI-agent-assisted by design - use your preferred agent, as you would on the job. We don't test memorized syntax; we assess engineering judgment: how you specify work, catch and correct the agent, and make architectural decisions. Expect a brief take-home plus a live pairing and design session</li><li>
Meet the Team (Tech Lead and Engineer) + live AI coding session (extension of our take-home test) (~55 minutes) - Experience working with your new team.</li><li>
Meet our Co-CEO (~25 minutes) - Gain insight into our product and business</li></ul><h4 class="jobSectionHeader">
