Full Job Description

Job Summary

FSA Capital is seeking a hands-on Lead Software Developer to support Nestly, an AI-powered home buying application developed by FSA Capital. Nestly is designed to transform the entire home purchasing journey into a single, streamlined experience. We combine institutional-grade market analytics with a certified vendor network and seamless multi-party communication to help buyers make smarter decisions, close faster, and save more.

The Lead Software Developer will serve as the technical backbone of the platform— responsible for the architecture, performance, and reliability of an app that guides users through the entire journey. From our AI-powered search engine and real-time pricing analytics to multi-vendor communication hubs and secure transaction workflows, you will build and scale the systems that make Nestly’s one-stop-shop vision a reality. This role is equal parts hands-on coding and technical leadership.

Key Responsibilities

Architect and maintain Nestly’s mobile application (iOS and Android) and supporting backend services, ensuring scalability from launch through rapid user growth.

Lead development of core platform features.
Design and implement the data pipeline that powers Nestly’s institutional-grade market analytics.
Build and maintain integrations with external services including MLS data feeds, certified vendor network APIs, payment processors, and mapping/geolocation services.
Establish and enforce engineering best practices: code reviews, automated testing (unit, integration, E2E), CI/CD pipelines, and documentation standards.
Own production infrastructure: server provisioning, auto-scaling, monitoring, alerting, incident response, and database management with automated backups.
Implement robust security measures for user data, transaction information, and financial documents shared within the platform.
Collaborate with the Product Manager to estimate technical feasibility, scope work, and plan sprints; provide clear technical trade-off analysis for product decisions.
Mentor junior developers as the engineering team grows; establish coding standards and onboarding practices that maintain code quality at scale.
Manage app store submission processes, build configurations, and release management for both iOS and Android platforms.

Required Qualifications

6+ years of software development experience with at least 2 years in a technical lead or senior engineering role.
Strong proficiency in mobile development (React Native, Swift, or Kotlin) and backend technologies (Node.js, Python, or Go).
Experience designing and operating cloud infrastructure (AWS, GCP, or Azure) including auto-scaling, load balancing, and CDN configuration.
Hands-on experience with relational and NoSQL databases, query optimization, and data modeling for transaction-heavy applications.
Proven ability to build and maintain RESTful APIs and/or GraphQL services consumed by mobile clients.
Experience implementing CI/CD pipelines and automated testing frameworks for mobile and backend deployments.
Strong understanding of application security, authentication (OAuth, JWT), encryption, and secure data handling practices.
Ability to make pragmatic technical decisions in a startup context — balancing long-term architecture with the need to ship quickly.

Preferred Qualifications

Experience building real estate, proptech, or marketplace platforms that aggregate data from multiple external providers.
Familiarity with AI/ML integration in production systems, including recommendation engines, natural language processing, or predictive analytics.
Experience with real-time communication systems (WebSocket, push notifications, in-app messaging).
Knowledge of geospatial data, mapping APIs (Google Maps, Mapbox), and location-based search functionality.
Experience with app store review processes, App Store Connect, and Google Play Console.
Contributions to open-source projects or a strong public portfolio of technical work.
