BLP Digital AG - Senior Fullstack Engineer
Requirements
• You've designed a backend service or API that other teams depended on, and kept it reliable and evolvable as usage grew. • You work well across teams. You align with product, integration, and infrastructure teams on contracts, priorities, and rollouts, and you can explain technical trade-offs to people who aren't engineers. • You improve existing production systems step by step, and you know when a rewrite isn't worth it. • You have strong fundamentals in type systems, composition, testing, and clean architecture, and you're comfortable working in a codebase built on functional patterns. • You're fullstack where it counts: you build on the components and design system our frontend experts maintain to ship admin UIs quickly, even though the backend is where you do your deepest work. • You think in products and take ownership. You translate business problems into precise specifications, weigh cost against benefit, work directly with customers when a setup needs it, and stay responsible for what you ship after it goes live. • Strong plus • Strong plus • Experience with distributed systems, Kubernetes, Temporal, or cloud infrastructure. • Experience with user provisioning (SCIM) and SSO (OIDC). • Experience running multi-tenant systems. • Domain knowledge in ERP, finance, procurement, or supply chain processes, or German language skills. • What you'll get • What you'll get • Ownership of visible outcomes. The areas you own decide how fast enterprise customers go live and how well BLP scales with them. • Ownership of visible outcomes. • Impact at scale. Every improvement you ship to the product core multiplies across all product teams and the 20'000+ people who use BLP daily. • Impact at scale. • Senior scope from day one. You'll lead technical initiatives and mentor engineers on a team that is actively growing its backend ownership. • Senior scope from day one. • Learn more about BLP and our values at blp.digital/company/careers. • Please note: Hybrid work in London office, or remote in wider UK and Europe.
Responsibilities
• Where you'll work. You join the Platform Team, about 10 engineers. At BLP, platform means the core of our product, not internal infrastructure: the shared services, data access layer, and design system that every product runs on. You work closely with the senior backend engineer who owns these areas today, in a large production Go codebase with well-established patterns. • Where you'll work. • What success looks like. In your first year, you own one core area end-to-end, for example, user provisioning, outbound email, cross-tenant capabilities, analytics, or workflow configuration, from the Go service to the customer using it. • What success looks like. • Build the service that product teams build on. Design, build, and evolve the core APIs behind document processing, approval workflows, administration, and analytics, with clear contracts so product teams can ship on top of them without workarounds. • Build the service that product teams build on. • Own the persistence layer. Each tenant has its own isolated MySQL database. You evolve the abstraction product teams build on (a tenant-scoped unit of work, typed repositories, and shared type-safe querying) so that isolation, transactions, and permissions are right by default. • Own the persistence layer. • Scale BLP for large enterprises. Extend our cross-tenant capabilities so customers with many subsidiaries and business units can manage users, permissions, and documents across all of them from one place, correctly, securely, and fast. • Scale BLP for large enterprises. • Own email, in and out. Own our email document ingestion and outbound email services, including the audit trail and its UI. • Own email, in and out. • Make setup self-service. Turn manual SSO, SCIM, and email setups into migration tools and admin UIs that customers and project managers can run on their own. • Make setup self-service. • Work with customers. Join onboarding calls with customer IT teams and project managers, get their setups running, and turn what you learn into better tooling. • Work with customers. • Own it end-to-end. From the Go service through the React UI to production, including tracing, metrics, and incident analysis after it ships. • Own it end-to-end. • Tech stack: Go, React/TypeScript, MySQL, Redis, Temporal, Kubernetes on GCP and AWS, GitHub CI/CD, and OpenTelemetry with Grafana, Prometheus, Tempo, and Parca for observability.
