Software Engineer

At Guac, we're on a mission to solve grocery food waste with predictive ML. We forecast exactly how much of each product will sell, to put an end to the millions of tons of food that goes to waste every single day due to bad inventory replenishment.

We're currently working with major supermarket chains in the US (you've probably shopped at some of them before), and we're backed by Y Combinator, 1984 Ventures, Collaborative Fund, and angels from Instacart and Citadel Securities.

We're seeking a talented Software Engineer to join our team in-person in New York to help shape the future of grocery!

About the Role

As a Software Engineer at Guac, you'll have significant ownership and influence on our engineering and product direction:

Data Engineering & Integration

Design and implement scalable data pipelines for processing inventory and sales data across multiple grocery chains

Build robust ETL workflows (Python, Dask, Dagster, GCP) for integrating with diverse customer systems

Optimize data flows to handle the scale and complexity of enterprise grocery operations

Backend Development

Design and build robust backend services that power in-store ordering and production planning products

Develop and maintain Python-based APIs using FastAPI on GCP

Collaborate directly with customers' technical teams to understand and integrate with their IT infrastructure

About You

At least 3 years of relevant software engineering experience and a minimum of a Bachelor's degree or equivalent in Computer Science

Strong proficiency in Python backend and API development

Excellent communication skills and commercial mindset, with experience in customer-facing technical roles

Bonus: Experience with data processing frameworks (Dagster, Airflow) and/or distributed systems

Why Work with Us

Join an early-stage team where you'll have real impact and ownership over technical decisions, strategy, and products used by our customers every day

Solve intellectually challenging problems at the intersection of software engineering, data, and ML that require deep thinking and creativity

Make a real-world impact on both climate and food security: the grocery industry is enormous (in the US, it accounts for ~4% of GDP), and we're tackling food waste at scale

Be part of a fast-growing engineering team that's transforming how major grocery chains operate
