MelodyArc delivers consistent outcomes for the work AI can't do alone — orchestrating data, rules, AI, and people in one governed system, with a full record of why. Our orchestration core (the Point Engine) lets enterprise operations teams configure agentic AI Operators that execute work end-to-end while leveraging existing business logic and human-in-the-loop workflows.
Role Overview
As an SDE 3, you'll be a senior, hands-on engineer and technical leader who ships business-critical capabilities on tight timelines. You will own the design and delivery of multi-component features, raise the bar on reliability and security, and help scale the team alongside the CTO through code reviews, mentoring, and pragmatic process improvements.
Key Responsibilities
Design, build, test, and operate scalable backend services (NodeJS/TypeScript) that power MelodyArc's orchestration and workflow capabilities.
Partner with the CTO to run, improve, and standardize the code review process to ensure increasing quality without excessive overhead or single-person bottlenecks.
Review designs and code for peers; mentor engineers; and improve shared standards (testing, code quality, CI/CD, documentation).
Lead the technical delivery of multi-sprint initiatives: translate product requirements into clear technical plans, milestones, and execution tradeoffs.
Drive system design for reliability, performance, and scalability (e.g., idempotency, retries, rate-limiting, multi-tenant isolation, graceful degradation).
Build secure, compliant solutions aligned to SOC 2 Type II practices (e.g., least privilege, audit logging, data handling, change management).
Own production readiness: instrumentation/observability, operational playbooks, incident response participation, and post-incident improvements.
Partner closely with Product, DevOps, and customer stakeholders to iterate quickly and deliver measurable customer outcomes.
Basic Qualifications
6+ years of non-internship professional software development experience, including hands-on development with NodeJS and TypeScript.
4+ years of experience in the design and architecture of new and existing systems (design patterns, reliability, and scaling).
Demonstrable experience leading technical projects: scoping, sequencing milestones, driving execution, and shipping to production.
Experience operating production services: debugging, incident response, and improving observability and on-call readiness.
Experience designing secure systems and applying secure SDLC practices aligned with SOC 2 Type II or similar compliance frameworks.
Preferred Qualifications
Experience across the full software development lifecycle: coding standards, code reviews, source control, build pipelines, automated testing, and operations.
Experience building complex, distributed systems (e.g., workflow/orchestration engines, event-driven systems, rules/policy evaluation, integrations).
Front-end proficiency with React, Redux, HTML5, CSS3, modern JavaScript (ES6+), and TypeScript.
Experience building integrations with enterprise systems (APIs, authn/authz patterns, webhooks, data sync, and auditability).
Experience with customer service operations and/or customer support platforms and workflows.
Location
Remote (United States).
Compensation
Base salary range: $150,000–$200,000 USD, plus equity. Final offer within the range depends on experience, level, and skills. This is a remote, US-based role; compensation is not set to Bay Area / NYC bands.
