Job description

Job Description

We are hiring a senior individual contributor to serve as the de facto technical lead for a small, fast‑growing B2B software company in the finance operations space. This person will operate across teams and systems, own long‑term architectural decisions, and set the engineering bar as the organization scales. You will work directly with the leadership team to translate ambiguous business goals into clear technical roadmaps and ship end‑to‑end features across the stack.

What you will do

• Define and drive technical direction across the full stack, focusing on the highest‑leverage problems and solutions.
• Lead complex, cross‑cutting initiatives end‑to‑end, including data modeling, schema design, migrations, backfills, and safe rollouts on relational databases and modern ORMs.
• Establish and continuously improve engineering standards: system design practices, incident response, observability, and reliability.
• Multiply team impact by mentoring other engineers, leading design and architecture reviews, and raising the overall quality bar.
• Partner with founders and product leaders on roadmap, trade‑offs, and build‑vs‑buy decisions that balance speed with long‑term maintainability.

Why This Role Is Compelling

You will be the most senior IC engineer at a venture‑backed, small team rapidly scaling a mission‑critical product for large enterprises. The product focuses on automating and modernizing traditionally manual finance back‑office workflows (such as invoicing, collections, and cash application) using AI‑driven workflows and deep integrations with existing systems. You'll have outsized ownership: your architectural decisions and technical standards will shape the product and engineering culture for years.

Qualifications

• Seniority and background: 8+ years of professional experience in full‑stack software engineering, ideally at a high‑bar technology company or venture‑backed startup, with broad ownership across the stack.
• Technical skills: deep proficiency in TypeScript; experience building with Node.js, React/Next.js, and production hosting platforms; familiarity with ORMs such as Prisma and relational databases like MySQL; experience with event‑driven architectures and orchestration tools (e.g., Temporal, Inngest).
• Leadership and collaboration: demonstrated ability to mentor and level up other engineers through code reviews, design reviews, and pairing; strong product sense and ability to partner closely with non‑technical stakeholders to define and deliver high‑impact functionality; comfortable turning loosely defined business goals into technical plans and execution.
• No Visa Sponsorship.

Why Is This a Great Opportunity

This is a rare opportunity to be the most senior IC engineer and de facto technical lead at a venture‑backed, fast‑growing organization.
