About ECP
ECP is a market-leading SaaS solution that enables senior living communities to better care for their residents. ECP is used in over 8,000 communities. We're looking to further expand by increasing the number of customers that use our software and increasing the scope of how we serve our customers by developing and releasing new products.
Senior living is deeply under-penetrated with software and ECP is one of the largest and fastest-growing software companies in the industry. We recently raised a growth round of equity to reinvest in our product, technology, and go-to-market. Our mission is to build world-class software that improves the quality of life for seniors and improves clinical, business, compliance, and operational performance for our customers.
The Role
Every delivery team at ECP depends on a set of shared components that none of them own. The authentication and identity layer every user passes through, the shared data services at the core of the product, and the messaging infrastructure connecting the platform are three of them, and they are not the only ones. When any of these has undocumented behavior, a reliability gap, or needs a coordinated change, the work falls to whichever team happens to be closest to it that sprint. We're standing up a platform organization to close that gap, and you'd be one of its first engineers.
ECP Intelligence sits here too. It's a set of role-based agents meant to get our users out of the software and back to their communities. Today it's a strategy. Nothing has been designed or written yet. Our data warehouse, which this team also owns, will give an agent what it can see. You own what it can do. An agent that only reads is a demo. One that acts has to act as a specific user, inside that user's permissions, through the same identity and domain services every other client of the platform goes through. That is your first mandate.
This is a builder role on a team of four senior engineers, reporting to the VP of Platform Engineering. You'll write the code these capabilities are made of, with a loud voice in how they get designed.
The stack. New code is Node and TypeScript. We're migrating off a ColdFusion legacy platform, and the two will coexist for a while. SQL Server and PostgreSQL, a mix of monolith and services, adopting domain-driven design and an event-driven architecture, all on AWS. This is a multi-tenant HIPAA product. You won't write ColdFusion, but you will design against it, because what you write has to serve both platforms at once.
What You'll Build
ECP Intelligence. You'll build the tool surface an agent acts through, the retrieval and context layer that grounds it in the right clinical and operational data, the serving path product teams call to reach a model, and the evaluation that catches a regression before a customer does. You'll also build the first agent workflows that run on it. This is clinical software, so you have to be able to prove what an agent cannot do.
The shared components. Which ones we take on first is an open question, and you'd help answer it. The shape of the work is the same either way. These are systems already in production that every team depends on, with behavior nobody wrote down and boundaries nobody drew on purpose. You'll take them over, give them interfaces worth depending on, and make the seams between the legacy platform and the newer services explicit.
The messaging backbone. The event bus works, but it's only partly adopted and nobody owns it. You'd take it the rest of the way, add contract testing so a service can be verified on its own, and support it as something the other teams can build on.
What We're Looking For
Required
You've built shared components or platform services that other teams depended on, and you stayed accountable for them afterward. This is not a first platform role.
Real depth in domain-driven design and event-driven architecture. You can explain why a bounded context sits where it does, what an anti-corruption layer bought you, and which flavor of event-driven you were actually doing.
You've built the production systems behind an AI feature, against data that was messy, governed, and inconveniently shaped. The model itself is someone else's problem.
You've carried a pager for a system other teams depended on.
Breadth across more than one language and paradigm, with real depth in at least one. Tell us about a time you had to get productive in an unfamiliar stack fast, and what that took.
Data modeling and query performance under real load. Some of our shared components sit on the hot path for every request.
AI-augmented development is already how you work, and you know where it holds up and where it needs a human check.
Preferred
Experience shipping meaningful customer-facing AI features (more than just a chatbot)
PHI or other regulated data in an AI or analytics path
Multi-tenant SaaS at scale, with tenant isolation as a data-layer concern
Node and TypeScript, SQL Server, PostgreSQL, AWS
Building alongside a legacy platform mid-migration, without the luxury of waiting for it to finish
Contract testing or service virtualization in an event-driven system
Mentoring engineers, or wanting to grow into it
What Success Looks Like
At six months, the AI foundation is real and at least one ECP Intelligence agent workflow is running in front of customers, taking work off a caregiver's plate that they used to do by hand.
The shared components and the messaging backbone are a longer job, and that work starts once the agent foundation is in place. The measure there is that teams build on these components without having to think about them, and spend their time on their own roadmaps instead.
