What the job involves
- We’re looking for an experienced Backend Engineer to join our engineering team as a senior IC focused on backend service development for a product for a new market currently under development
- Our platform is mission-critical, with many moving parts: distributed services, relational and NoSQL data stores, message queues, real-time data pipelines, and a growing set of APIs that must perform reliably at scale
- In this role, you’ll take ownership of designing and building scalable backend services that sit at the core of the product
- You’ll work across Java-based microservices, databases, and messaging layers to ensure the stack is cleanly designed, performant, observable, and maintainable
- You’ll also be central to shaping how we design and manage APIs and how backend systems integrate with front-end applications and core infrastructure
- This is a highly impactful position where you’ll define patterns and practices for service design and data architecture while mentoring others and shaping the future of our backend engineering
- Architect & Build Services: Design, implement, and scale backend services in Java using frameworks like Spring Boot or Dropwizard
- Data & Persistence: Design data models and persistence strategies across Postgres and NoSQL stores (DynamoDB or similar)
- Messaging & Integration: Build and operate systems that leverage message queues (SQS, Kafka, etc.) for asynchronous communication and event-driven workflows
- API Design & Management: Define, document, and evolve REST APIs using OpenAPI, ensuring consistency, clarity, and strong collaboration with front-end teams
- Optimize for Scale & Reliability: Ensure services are performant, observable, fault-tolerant, and capable of handling 24/7 production workloads
- CI/CD & Tooling: Own build pipelines and service delivery using Gradle, automated testing, and CI/CD best practices
- Collaborate Cross-Functionally: Work closely with front-end engineers to design API contracts, and with infrastructure engineers to ensure backend services integrate seamlessly into our containerized, cloud-native platform
- Service & Data Design Leadership: Set patterns for clean, consistent API design, service boundaries, and data architecture across the engineering org
- Mentor & Guide: Provide technical leadership, perform design and code reviews, and coach teammates in backend engineering best practices
Our take
In the event of an accident or fall, elder care facilities largely rely on outdated nurse call systems, which can mean residents wait longer than necessary to receive care or attention. Sage solves this problem by providing carers and institutions with a modern operating system.
Sage's caregiver app allows carers to identify patients in need of help, as well as providing tools for triage and the reviewing of care information. As one of the first companies to bring a data-driven approach to elder care in this way, Sage has received strong attention and raised impressive funding, most recently with the acquisition of $65M.
The age-tech market is growing steadily, and becoming more competitive, which means Sage will need to invest heavily in scaling its outreach in order to consolidate its progress. That said, it has established an early foothold which gives it a place to work from as it develops into the future.
