Backend Tech Lead – AWS | TypeScript Node.js | IoT

*About Us*

We're a fast-growing startup building AI-powered automation and logistics systems for hospitals. Our engineering team is hiring a *Backend Tech Lead* with deep experience in *Node.js*, *AWS Lambda*, and *IoT-based distributed systems*. This is a hands-on leadership role in a *real-time, event-driven environment*, driving *serverless architecture* and helping coordinate *robotics* and *healthcare automation* at scale.

*Role Overview*

As Backend Tech Lead, you will architect and build the distributed services that move autonomous robots and vital medical supplies through complex environments. This is a hands-on leadership role: you will write production code, own architectural decisions, and steer the evolution of a real-world logistics platform on AWS.

*What You’ll Do*

* Design and ship distributed services for real-time robot coordination, scheduling, and telemetry
* Own the architecture and data models for our event-driven stack (IoT Core, EventBridge, Lambda, Step Functions, DynamoDB, and more)
* Build everything as code using Serverless Framework or CloudFormation, with fully automated infrastructure provisioning
* Harden the platform for resilience, observability, and secure device-to-cloud communication (Datadog, SSM, least-privilege IAM)
* Drive engineering rigor in TDD, CI/CD with GitHub Actions, and p99 performance tuning
* Collaborate with product and robotics teams to align capabilities and constraints as we scale
* Elevate the team through hiring, mentoring, and insightful code reviews

*Experience Level*

* 7+ years designing, building, and owning distributed backend systems at production scale
* Deep AWS expertise across IoT Core, Lambda, Step Functions, DynamoDB, EventBridge, secured with least-privilege IAM and provisioned via Infrastructure as Code using Serverless Framework, CloudFormation, or Terraform
* Node.js and TypeScript specialist with a record of low latency, event-driven services for IoT ingestion, real-time analytics, and high-throughput messaging, including hands-on tuning to meet strict p99 targets
* Quality-first engineer who practices rigorous TDD, full automation, and CI/CD, embedding resilience, monitoring, and alerting for around-the-clock reliability
* Clear, empathetic communicator who mentors through thoughtful code reviews and pairing, and actively supports hiring and onboarding

*What You Bring*

* Strategic mindset with confidence in making trade-offs that balance speed, quality, and long-term maintainability
* Craftsmanship that yields maintainable, testable, and observable code that thrives in production
* Production savvy understanding of security, scalability, and performance best practices
* Leads by example through design guidance, mentoring, and thorough code reviews
* Takes ownership of business-critical systems and drives them to success

*Bonus Points*

* Domain experience in robot coordination, scheduling, or telemetry
* Familiarity with elevator systems, building automation, or other IoT integrations
* Background in migrating monoliths to service-oriented architectures

*Why You’ll Love It Here*

* High impact: every line of code improves hospital logistics and patient outcomes
* Fast pace and ownership: design it, ship it, and take pride in the results
* Purpose-driven work: build robotics systems for high-stakes environments like hospitals and labs
* Hybrid flexibility: regular on-site collaboration in Tel-Aviv with remote days when needed

*Ready to build the infrastructure powering next generation healthcare logistics?*
