About The Position

At PLACE, we're building a category-defining company at the intersection of real estate, technology, business services, and the consumer. As a profitable, hypergrowth startup on the path to an IPO, our standards are high, our team is scrappy, and our commitment is to execute the best work of our lives. This is YOUR CHANCE to shape the backbone of a company that's scaling rapidly and innovating boldly. As our Senior Fullstack Engineer, you'll partner with the CTO, founders, and executives to build and scale our mortgage technology platform, shipping features end to end across a mix of microservices and monolith architectures, with a focus on backend systems and third-party integrations. If you thrive in complexity, entrepreneurial problem-solving, and believe in scaling through tech and AI, this is your PLACE.

Requirements

7+ years building and running production web applications
Experience taking a problem from a vague description to a shipped, monitored solution
Proficiency in Ruby on Rails, including API-only services, ActiveRecord, PostgreSQL, background jobs, and RSpec
Comfortable shipping polished UI with React and TypeScript
Experience with GraphQL (ideally Apollo) on both server and client
Experience building distributed, event-driven systems
Knowledge of how to debug failures that span services, using retries, idempotency, and eventual consistency
Experience taming third-party integrations (REST, SOAP, webhooks) and partner APIs that are slow, inconsistent, or poorly documented
Strong instincts for security and multi-tenant data isolation
Advanced daily use of AI and agentic coding tools, ability to describe context structuring for agents and verify their output
Ability to build tooling that makes other engineers more effective
Clear communication skills: ability to write a strong design doc, explain a production incident to a customer success manager, and disagree productively with a product manager
Experience owning production through on-call, incident response, observability, and blameless postmortems

Nice To Haves

Experience in mortgage tech or a similar regulated, integration-heavy domain (fintech, lending, insurance, payments, healthcare)
Familiarity with LOS platforms (Encompass, MortgageBot, Byte)
Familiarity with MISMO standards
Node.js/TypeScript services
Elasticsearch
Redis
Docker
AWS
CI/CD
Saga or workflow orchestration patterns
History of mentoring engineers and leading cross-team projects

Responsibilities

Design, build, and maintain features across Rails API services, TypeScript/Node services, a GraphQL gateway, and React frontends
Own integrations with external platforms (LOS systems, mortgage insurance providers, document and e-sign vendors), including data mapping, sync and reconciliation, retries, and idempotency
Design and evolve asynchronous, multi-step workflows using message queues (RabbitMQ, SNS/SQS), Sidekiq background jobs, and saga-style orchestration
Keep our multi-tenant platform correct and secure, respecting partner boundaries in every query and event
Lead technical design for significant features by writing design docs and architecture decision records, weighing trade-offs, and building alignment before you build
Identify and pay down technical debt, improving service boundaries, module design, test coverage, and developer experience
Hold a high bar in code review and help set engineering standards across the team
Join the on-call rotation, lead incident response, and follow through on root-cause fixes that prevent recurrence
Use observability tools and CI/CD to keep the platform healthy, and improve them where they fall short
Work directly with Customer Support & Success on lender-reported escalations, reproducing issues, investigating sync problems with external LOSs, and explaining findings clearly to non-engineers
Partner with Product Managers to refine requirements, uncover edge cases early, and propose simpler alternatives
Work with UI/UX Designers to turn designs into polished, accessible interfaces, and push back constructively when technical constraints affect the experience
Mentor other engineers through pairing, code review, and design feedback, including on effective AI-assisted workflows
Lead on AI-assisted engineering by using agentic coding tools (Claude Code, Cursor, Codex) daily to plan, implement, test, debug, and review, and by delegating well-scoped work to agents and reviewing their output rigorously
Build and maintain shared AI tooling for the team, including agent instruction files (CLAUDE.md/AGENTS.md), reusable skills and prompts, MCP servers connecting agents to internal systems, and automated workflows
Set and follow guardrails for AI use: verify agent output, never expose secrets or customer data, and know when a task needs a human-written solution
