Junior Software Engineer (m/w/d) - (Frankfurt/ Remote) in Berlin

About Willidrop

Willidrop is a managed marketplace for cross-border car transport in Europe. We connect dealers and carriers to make transport fast, reliable, transparent, and fully digital — from instant quoting to delivery documentation. We’re building the “operating system” for a highly fragmented logistics category and scaling a platform + ops model that’s proven to handle high throughput with a lean team.

The role

We’re hiring an early-career engineer who wants real ownership — not a title. You’ll join early, work closely with the founder and an experienced part-time product/engineering lead (6–12 months overlap), and progressively become the primary owner of the production system. This is not a CTO / co-founder role. It is a role where you’ll learn how to run and evolve a real marketplace platform end-to-end.

Tasks

What you’ll work on (real responsibilities, day 1)

You’ll contribute across the system that powers:

• Dealer & customer-facing booking + tracking flows (portal + updates)
• Carrier-facing workflows (jobs, pricing, documentation, negotiation)
• Internal tooling: route planning, admin panel, pricing operations

Typical tasks

• Fix production issues, improve reliability, and reduce manual ops effort
• Ship small-to-medium features across frontend workflows, backend logic, and automation
• Improve data quality (syncs, validation, edge cases) and observability (alerts, logs, dashboards)
• Tighten security + access control (roles, permissions, data exposure)
• Help shape the next iteration of the platform as we scale volume and automate more of the journey

Your ownership path (how you grow)

• Months 0–2 (guided): Ship fixes/features with tight feedback, learn the system end-to-end
• Months 3–5 (primary operator): You own day-to-day stability and small features independently
• Months 6–12 (system owner): You’re the default person for “how does this work?” and “can we change this safely?” — with support for bigger architectural decisions

Current stack (pragmatic, evolving)

• A workflow-oriented product UI augmented with custom JavaScript components
• A Postgres-based backend platform with authentication, access control, and server-side logic
• A custom-built mapping & routing application used for core domain logic
• Automated background jobs and data pipelines connecting internal systems and external tools
• Modern CI/CD pipelines with environment separation and secure secret handling

How we build: Agentic engineering is a must

We actively embrace agentic engineering and modern AI-assisted development (e.g., coding agents, automated refactors, test generation, AI-supported debugging, structured prompt workflows). We’re looking for someone who is curious, hands‑on, and proactive about using these tools responsibly to move faster and raise quality. You don’t need to be an expert today — but you do need the mindset: open, experimental, and pragmatic. If you’re fundamentally opposed to this direction, it’s probably not the right environment for you.

Requirements

What we’re looking for

Must-haves

• Strong JavaScript fundamentals, comfortable working across backend scripts and browser-based code
• Solid understanding of relational databases (Postgres) and safe schema evolution
• Experience working with a backend platform or BaaS (auth, permissions, server-side logic), preferred supabase
• Ability to debug and improve data flows and background processes (idempotency, retries, edge cases)
• Practical experience with API integrations (authentication, rate limits, error handling)
• Clear ownership mindset: you can break work down, deliver incrementally, and keep systems stable
• Openness to agentic engineering and active use of AI tools as part of daily development

Nice-to-haves

• Experience working with low-code/no-code systems alongside custom code
• Exposure to geospatial, routing, or map-based products
• Familiarity with serverless functions or lightweight backend services
• Experience with CI/CD pipelines and multi-environment deployments
• Background integrating operational tools into production systems

Benefits

What you’ll get

• Real ownership early: you won’t be “ticket‑taking” forever
• Direct mentorship + a clear handover path to full technical ownership
• A product that’s already live with clear market pull and a platform vision spanning dealers + carriers
• Competitive salary and employee participation program
• Location: preferred onsite in Frankfurt, remote possible
