The role
Figure out where AI can make a real difference for a customer, then lead the work to make it happen.
You'll embed with operators and executives, understand how the business runs, and turn what you find into a deployment plan. You'll write code to test ideas, build integrations and prototypes, and debug issues alongside our engineers. You'll own the engagement through rollout and adoption.
Bring the judgment to choose the right problem, the engineering experience to build and test a solution, and the presence to earn customer trust.
What we're building
Mason is accelerating development of the built world with AI. We turn fragmented documents, databases, emails, and operational knowledge into a company brain people and agents can use to automate work and eliminate errors.
We're growing fast - we have an 8-figure pipeline of projects and are looking for great engineers and builders to join our team.
Our founding team includes a repeat founder who sold his last company to Coinbase, a former tech lead at Meta Superintelligence who co-created Meta AI, and a development director who built $2B+ of projects.
What you'll own
Find the valuable problem. Work with executives and operators to understand the workflow, the data, the exceptions, and what an improvement is worth.
Shape the solution. Define scope, priorities, and success measures. Write code, work with customer data and APIs, and build working prototypes to test assumptions.
Lead the engagement. Own the roadmap, customer communication, expectations, and decisions that keep delivery moving.
Get it into use. Contribute code and debug integrations alongside our engineers, then lead rollout, training, and adoption. Measure whether the customer's work actually improves.
Build what repeats. Turn field lessons into better product decisions, deployment practices, and tools for the next customer.
Who we're looking for
4+ years across software engineering and technical customer delivery, including hands-on experience building and shipping software.
A complex initiative you personally drove to a result with customers and multiple stakeholders.
Executive presence: you turn difficult requests into workable plans and communicate hard messages without losing trust.
Strong coding skills in Python, TypeScript, or a similar language. You can independently write, test, and debug software, build API integrations, and work in an existing codebase.
Product judgment, fast learning, and responsibility for the outcome.
You may now be a founder, consultant, product manager, solutions engineer, or deployment lead. You should have built software yourself and still be comfortable getting into the code.
Why join Mason
Work directly with founders and decision makers at firms managing billions in AUM. You'll help choose what gets built, lead the engagement, and see the result with the customer.
Your judgment will shape our product, our deployment approach, and the team we build.
Team and culture
CEO is a second-time founder who sold his last company to Coinbase
CTO was previously a tech lead at Meta Superintelligence and co-created Meta AI

Small, intense, low-ego. High ownership, direct feedback, board game nights, and lots of laughs.
