Job summary

Jiffy is seeking a Sr. Software Development Engineer to lead AI-driven coding agents orchestration for an e-commerce platform. You will drive end-to-end feature delivery across storefront, checkout, internal tools, and platform services while guiding parallel AI work streams.

A strong background in scalable systems and agent-based workflows is essential. The role emphasizes architectural judgment, hands-on coding supervision, and the shift to AI-native engineering practices.

Qualifications

• Bachelor’s degree in Computer Science, Engineering, or a related field.
• 5+ years of professional software engineering experience shipping production systems at scale.
• Hands-on experience using AI coding agents (Claude Code, Codex, Cursor, or equivalent) as a primary development tool.
• Proven ability to run multiple agents in parallel and manage concurrent work streams without losing quality, context, or accountability.
• Strong software design fundamentals: OO design, API design, data modeling, distributed-system reliability, and performance.
• Proficiency in at least one server-side language (Ruby, Python, Go, Java, or equivalent) and one modern front-end stack (React / TypeScript or equivalent).
• Experience with relational databases (Postgres / MySQL), SQL, and building or consuming REST or GraphQL APIs.
• Elite code-review skills: the ability to read, critique, and correct diffs at speed.
• Strong written communication — clear intent, clear PR descriptions, clear prompts.
• A high level of integrity, accountability, and ownership, with a commitment to excellence.
• Desire to work in a fast-paced, ambiguous, high-autonomy environment.

Responsibilities

• Orchestrate AI coding agents across 3–6 concurrent work streams spanning features, refactors, bugs, and investigations.
• Own features end-to-end: translate product intent into specifications, decompose work into agent-executable plans, drive implementations, review diffs, run QA, land PRs, verify production health.
• Design and architect scalable systems across Rails 8 / Solidus e-commerce, GraphQL APIs, React 19 front end, Kubernetes infrastructure.
• Raise the quality bar on AI-generated code by catching hallucinated APIs, securing idiomatic patterns, and avoiding structurally weak output.
• Build and evolve internal AI tooling: author skills, rules, prompts, MCP integrations, evaluation harnesses.
• Operate with production rigor: drive tests coverage (RSpec, Vitest, Playwright), monitor deploys, respond to incidents.
• Partner cross-functionally with Product, Design, Ops, and engineering teams; mentor on AI-native workflows.
• Identify and automate remaining manual work via agents.
