Job Description

Full-Stack Own the end-to-end solution architecture in Typescript and Go.

- Implementing robust patterns for API design, error handling, and retry logic across integration workflows.

- Architectural Stewardship: Author Architecture Decision Records (ADRs) for all major integrations and platform decisions, ensuring alignment with event-driven, asynchronous, and cloud-native principles across the organization.

- Backend Engineering: Design and build isolated, decoupled microservices in TypeScript and Go that serve as the reference standard for correctness, performance, and maintainability.

- Frontend Engineering: Defi ne the frontend standards and component architecture for integration surfaces — owning patterns for how integration configuration, connection status, and data flows are built across the platform, and ensuring complex backend behaviour translates into experiences that are intuitive and built to last.

- Cloud Infrastructure: Own infrastructure-as-code practices using AWS CDK across multi-region environments. Make authoritative decisions on data store selection and configuration across DynamoDB and Aurora RDS.

- Resiliency & Eventing: Build highly idempotent outbound APIs with exponential

- backoff algorithms. Architect strictly asynchronous webhook ingestion pipelines using AWS EventBridge and SQS.

- Enterprise Observability: Champion a culture of production visibility — instrumenting services with OpenTelemetry, designing Datadog dashboards tracking key SLIs (availability, latency, throughput), and driving incident response maturity.

- Security & Compliance:



Ensure all integration services enforce strict tenant isolation, align with GDPR data minimization principles, and meet SOC 2 Type II cryptographic requirements. Be the final technical voice on security posture for the integrations domain.

- Mentorship & Standards: Establish and uphold engineering best practices across the integrations team. Mentor senior engineers through design reviews, code reviews, and structured technical growth opportunities.

- Operational Excellence: Lead Operational Readiness Reviews (ORRs), defi ne CI/CD quality gates, and own the end-to-end lifecycle of critical integration systems from inception through production monitoring.

- Cloud Infrastructure: Work with AWS serverless services (Lambda, EventBridge, SQS, CDK) to build and deploy integration pipelines.

- Hands-on Development & Code Quality Write and review clean, efficient, and testable code, adhering to best practices and enforcing coding standards.

- Lead Agile Execution & Delivery Actively participate in Agile ceremonies and drive sprint planning, backlog grooming, retrospectives, and daily stand-ups with a focus on delivery and continuous improvement.

- Ensure Cross-Team Collaboration Act as the bridge between developers, DevOps, product owners,



and business stakeholders to align technical solutions with business goals. Promote a Culture of Technical Excellence Advocate for performance optimization, secure coding, maintainability, and continuous learning across the engineering team.

Must haves

- Extensive experience as a lead, staff, or principal engineer in a high-growth SaaS environment

- Deep expertise in TypeScript and Go, with a track record of production microservices at scale

- Mastery of AWS serverless paradigms — including CDK, EventBridge, SQS, Lambda, and Secrets Manager

- Proven ability to design decoupled, event-driven architectures and articulate the trade-offs of distributed systems

- Solid observability practice — hands-on with Datadog, OpenTelemetry, structured logging, and distributed tracing

- Exceptional communication skills; able to lead through infl uence and build alignment across engineering and product stakeholders

- Experience authoring ADRs or equivalent technical design documentation

Nice to haves

- Prior experience building CRM integrations (Salesforce, Microsoft, HubSpot, or similar)

- Familiarity with PHP, Kotlin, or Python for legacy service transitions

- Experience building and maintaining SDK packages for third-party developers

- Working knowledge of AI-fi rst development tooling and practices
