About the Company

We are partnering with a well-funded early-stage (sub-10 person) US-based developer-tools company building next-generation infrastructure to improve the reliability performance and correctness of modern by experienced engineers who care deeply about automated testing runtime validation and delivering fast high-signal feedback to developers the company has already validated product-market fit with paying customers. This is an opportunity to join at a pivotal growth stage and help accelerate the technical roadmap.

The Opportunity

This is a high-impact Senior Software Engineer role focused on core infrastructure and developer-facing tooling.

You will work at the intersection of:

Systems design
ML-adjacent data processing
Backend/platform engineering
Developer productivity tooling

You will build systems that ingest code and runtime signals perform large-scale analysis and surface clear actionable insights directly within developer workflows.

As an early engineering hire you will help shape architecture decisions engineering standards and long-term platform direction.

Key Responsibilities

Own and evolve significant portions of the core engine that analyzes and validates software behavior across large codebases.
Design and implement highly reliable low-latency services to collect process and store:
- Execution traces
- Test results
- Runtime artifacts
- Observability signals
Build developer-facing APIs CLIs and UI workflows that translate complex analysis into actionable insights.
Collaborate closely with founders and early engineers on system architecture and technical roadmap.
Partner with early design customers to translate real-world developer pain points into scalable product features.
Take loosely defined problems design pragmatic solutions ship iteratively and own quality end-to-end.

Required Qualifications
