Macroscope
About Macroscope
Macroscope aims to be the source of truth of what's happening for any company that builds software. Our mission is to give leaders clarity and engineers time.
We help leaders understand how their products and codebases are evolving-what's changing, who's working on what, and where progress is happening-grounded in the ultimate source of truth: the code.
Macroscope is founded by former entrepreneurs who have started and sold multiple companies, and operated as product/engineering executives at public tech companies. We're fortunate to be supported by the best VC firms and angels in the business, including Lightspeed Venture Partners, Thrive Capital, Google Ventures, and Adverb.
About the role
We're looking for a
Senior Applied ML Engineer
to design, build, and optimize the machine learning and AI systems that power Macroscope's core features. You will have ownership and agency of our systems from end to end - from data collection and evaluation, to model experimentation, to productionizing our systems at scale.
This is a deeply cross-functional role where you'll own the ML/AI lifecycle of one of the most critical surface areas of our product:
AI Code Review . Working alongside our co-founders, you will be responsible for making the decisions that will determine how we build and improve the product, everything from building high-quality datasets, running experiments, interpreting results, and making architectural decisions to improve model performance. You will also play a lead role in designing and building the software that integrates the models with our backend application and product experience. This is a unique opportunity to have an immense amount of impact on how we evolve our product.
Our technology stack:
Typescript/React (front-end), Golang (backend), Temporal, Google Cloud (GCP), Postgres, Terraform, custom-built AST "code walkers" in various languages (Golang, Typescript, Swift, Python, Rust)
Qualifications 8+ years of experience
in applied ML, data science, or ML infrastructure roles. Proven track record of
designing, training, and deploying ML models
in production at scale. Strong skills in
data curation and evaluation
- understanding what data to collect, how to clean and label it, and how to measure success. Experience writing production-grade code and building robust pipelines connecting
data → models → backend systems . Deep intuition for model behavior and data representation - you know how to experiment, interpret results, and iterate effectively. Experience architecting
complex distributed systems
and optimizing them for performance and reliability. Hands-on experience with common ML/AI frameworks (e.g. PyTorch, TensorFlow) and working knowledge of LLMs and RAG systems. Comfortable in a
fast-paced, high-agency startup environment , where priorities shift and you help define what to do next. Experience in
Golang
(the primary language of our backend systems) is a strong plus, but is not required. Bonus: experience with GCP infrastructure, working with Temporal for workflow orchestration, or building internal ML platforms. About you You are extremely high agency.
We are a small startup and we intend to keep an extremely flat organizational structure for as long as possible. Instead of relying on people managers, product managers and heavy processes, we rely on exceptionally talented individuals with high agency to be self-motivated towards contributing to our mission. You want to work at an early stage start-up.
The default state of any startup is failure. The only way to overcome the daunting odds of making a startup venture successful is for a densely packed group of insanely hard working and talented people to work together to building something useful to and loved by customers. If you're not willing to work extremely hard on something high risk, this startup isn't for you. You act like an owner.
You put immense care and craft into what you build because you take responsibility for all parts of the product. You don't walk past broken windows. You care about what we're building.
Life's too short to work on something you're not passionate about. We are a small group of ambitious people who want to build something insanely great that we want to use, and that we think every company will want to use. If our mission and product doesn't resonate with you, we understand and would encourage you to find something that does.
