MelodyArc

5d • Remote

About The Position

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.

Requirements

• 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.

Nice To Haves

• 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.

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.
