Principal Software Engineer

Workato; Berlin; Vor Ort; EUR 120.000 - 170.000; Vollzeit

Zusammenfassung

Workato is seeking an exceptional System Architect to lead platform architecture across a scalable, secure, cost-efficient stack in Berlin. This hands-on role requires deep technical expertise and strategic influence on performance, reliability, and modularity.

You will design microservices, craft production-ready specs, and mentor teams while collaborating with Product, Security, SRE, and Infra. Expect rigorous architectural governance, ADRs, and zero-downtime migration planning.

Qualifikationen

• 8+ years building scalable distributed systems with 3+ years in System/Platform Architect roles.
• Proven experience architecting large microservice environments (100+ services) and monolithic apps.
• Strong Golang coding skills; write production-quality code.
• Experience with Protocol Buffers, gRPC, WebSockets, Kafka, PostgreSQL.
• In-depth knowledge of OAuth 2.0/OIDC, JWT, mTLS, zero-trust architecture.
• Hands-on Kubernetes, Docker, CI/CD, Terraform; distributed systems patterns (Saga, retries).

Aufgaben

• Design microservices and platform features from concept to production-ready specs.
• Create technical designs and proof-of-concepts in Golang.
• Architect secure, fault-tolerant systems with automated failover and end-to-end encryption.
• Review designs and lead architecture decisions across teams.
• Write ADRs, runbooks, and API specifications; plan migrations and deprecations.

Jobbeschreibung

We are looking for an exceptional System Architect to lead the design and evolution of our platform architecture. This is a hands-on role requiring deep technical expertise in building secure, scalable, and cost-efficient systems. You will be responsible for critical architectural decisions affecting system performance, security, reliability, and modularity across our entire platform.

In this role, you will also be responsible to:

Architecture & Design

• Design microservices and platform features from concept to production-ready specifications
• Create technical designs for complex system components and develop proof-of-concepts in Golang
• Architect secure, fault-tolerant systems with automated failover, circuit breakers, and end-to-end encryption
• Analyze existing system architecture to understand current implementations and plan gradual replacement of legacy components
• Plan implementation phases, migration strategies, and feature deprecation timelines

Architectural Governance & Collaboration

• Review and approve architectural designs from engineering teams with detailed feedback
• Lead architecture review sessions and facilitate technical decision-making across teams
• Partner with Product Managers, Dev Leads, Security, SRE and Infrastructure teams to establish platform-wide standards
• Lead threat modeling exercises and drive technical consensus for platform-wide initiatives
• Mentor engineers on architectural best practices and resolve complex technical challenges

Documentation & Planning

• Write comprehensive technical documentation including ADRs, design documents, runbooks, and API specifications
• Create visual system diagrams and research technical solutions from diverse sources
• Design zero-downtime migration strategies and define acceptance criteria for architectural changes

Requirements

• Qualifications / Experience / Technical Skills
• 8+ years building scalable distributed systems, with 3+ years in System/Platform Architect roles
• Proven experience architecting both large microservice environments (100+ services) and monolithic applications
• Strong hands-on Golang coding skills - must write production-quality code
• Communication & Data: Protocol Buffers, gRPC, WebSockets, Kafka event streaming, PostgreSQL (partitioning, replication, HA)
• Security & Authentication: OAuth 2.0/OIDC, JWT, mTLS, data encryption, public key cryptography, zero-trust architecture
• Infrastructure & Operations: Working knowledge of Kubernetes, Docker, CI/CD pipelines, Infrastructure as Code (Terraform), distributed systems patterns (Saga, circuit breakers, retries)
• Scale: Experience with systems handling millions of requests/events per day
• Exceptional technical writing and communication abilities for diverse audiences
• Experience planning phased implementations and leading complex cross-team projects
• Proven track record with feature flags, gradual rollouts, and zero-downtime deployments
• Ability to facilitate architectural decision-making and create technical roadmaps
• Mentorship mindset and cost analysis capabilities
• Experience with AI-assisted workflows, particularly in system analysis and hunting for inconsistencies and corner cases.

Nice to Have

• Additional Languages: Ruby, Rust, Python, Java, C++, Kotlin-multiplatform
• Advanced Security: Key Management Systems (HSM, AWS KMS), Secrets Management (Vault), specific crypto algorithms
• Extended Infrastructure: Service mesh (Istio, Linkerd), NoSQL databases, Redis clustering, stream processing (Flink, Spark)
• Cloud & Compliance: AWS/GCP/Azure expertise, PCI-DSS, HIPAA, SOC2
• Community: Open source contributions, conference speaking, technical writing 8+ years building scalable distributed systems, 3+ years in System/Platform Architect roles, Experience architecting large microservice environments (100+ services) and monolithic applications, Strong hands-on Golang coding skills, Proficiency in Protocol Buffers, gRPC, WebSockets, Kafka, and PostgreSQL, Knowledge of OAuth 2.0/OIDC, JWT, mTLS, and zero-trust architecture, Working knowledge of Kubernetes, Docker, CI/CD, Terraform, and distributed systems patterns (Saga, circuit breakers), Experience with systems handling millions of requests/events per day, Exceptional technical writing and communication abilities, Experience with phased implementations and cross-team projects, Track record with feature flags and zero-downtime deployments, Ability to create technical roadmaps and facilitate architectural decisions, Experience with AI-assisted workflows for system analysis
