[Hiring] Principal Software Engineer, GO & Rust (Engine) @Workato

Role Description

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.

Qualifications

• 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.

Requirements

• 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.
