Get to Know Darwoft At Darwoft, we build digital products with heart. We're a Latin American technology company focused on creating impactful, human-centered software in partnership with companies around the globe.
Our remote-first culture is built on trust, continuous learning, collaboration, and strong engineering standards. We work with international teams solving complex product and technology challenges where our engineers can have a direct impact on the product.
If you're looking for a place where your technical judgment matters and where you can contribute beyond simply executing tickets, welcome to Darwoft.
About the Opportunity We're partnering with an innovative software company building a modern transaction platform for organizations managing complex M&A; processes.
The platform brings together document workflows,



collaboration, approvals, diligence, transaction management, and AI-powered capabilities within a single SaaS product.
What makes this opportunity particularly different is the way the engineering team builds software.
The product has been developed using an
AI-native engineering approach
, with tools such as
Claude Code, OpenAI Codex, and other AI coding agents
deeply integrated into the development workflow.
We're looking for a highly experienced
Senior / Staff Software Engineer
who can combine strong software engineering fundamentals with this new way of building software.
This is
not a traditional AI/ML Engineer role
.
You won't be training machine learning models or working primarily on Data Science. Instead, you'll be engineering production software, navigating a large existing codebase, making architectural decisions, improving reliability, and using AI coding agents to dramatically increase development velocity.
The ideal person is a
builder first
: highly technical, pragmatic, product-oriented, low-ego, and comfortable taking ownership of complex systems.
What You'll Be Doing
Navigate, understand, and evolve a large existing production codebase.
Design and implement new product capabilities across a complex SaaS platform.
Make pragmatic architectural and system design decisions as the product continues to scale.
Identify technical debt, architectural risks, reliability issues, and opportunities for improvement.
Use
Claude Code, Codex, Cursor, Copilot, or similar AI coding agents
extensively throughout the software development lifecycle.
Leverage AI agents to explore codebases, design implementations,



generate and refactor code, debug issues, write tests, and accelerate delivery.
Build and evolve backend services, APIs, integrations, data models, and application workflows.
Contribute across the application stack when needed.
Strengthen automated testing, maintainability, observability, reliability, and production readiness.
Improve development workflows, tooling, automation, and engineering practices.
Troubleshoot complex issues across application, data, and infrastructure layers.
Balance development speed with software quality and long‑term maintainability.
Work closely with product leadership to translate business problems into effective technical solutions.
Help a small engineering team achieve significantly greater development leverage through AI‑assisted engineering.
What You Bring
Strong professional experience building and operating
production software systems
.
Excellent software engineering fundamentals, including
architecture, system design, debugging, testing, and maintainability
.
Experience working with
large or complex existing codebases
.
Strong backend or full‑stack engineering experience using modern programming languages and frameworks.
Experience building modern
web applications and SaaS products
.
Strong understanding of
APIs, application architecture, integrations, data modeling, and distributed systems
.
Experience with relational databases and production data environments.
Strong understanding of automated testing and modern software development practices.
Familiarity with cloud environments, CI/CD pipelines, deployments, and production operations.
Ability to reason through technical trade‑offs and make pragmatic architectural decisions.
Strong ownership and ability to work independently in an evolving product environment.
Product mindset: you understand not only
how
to build something, but also
why
it should be built.
