Fullinfo
Brazil · Contract · Mid-Senior

Fullinfo is looking for a Senior Backend TypeScript Engineer to help build the core of its company intelligence platform. You will work on a fully serverless AWS backend in TypeScript, where clean architecture, readable code and long term maintainability matter more than clever engineering theatre.


(Please be aware you need to be located in CET OR LATAM timezone)


About Fullinfo

Fullinfo is building a B2B company intelligence platform.

The platform crawls more than 300 million active domains and turns messy web data into clean, structured and searchable company profiles. Sales and marketing teams use Fullinfo to find companies, contacts and insights that are normally hidden across websites, directories, registries and industry sources.


The backend runs fully on AWS, written in TypeScript and built around serverless services like Lambda, S3, DynamoDB and SQS. The frontend is built in Angular. GraphQL is used where it makes sense.


The team is small, international and senior. Around 11 people work across backend, frontend, UX UI, DevOps and machine learning. The culture is direct, calm and quality driven. People say what they do and do what they say.


Role description

As Senior Backend TypeScript Engineer, you will work on the backend services and data pipelines that power Fullinfo’s platform.

This is not a management role or an abstract architecture role. You will write code, build services, improve data flows and make sure the backend stays simple, scalable and maintainable.

You will work closely with the CTO, principal engineer and other backend engineers. There is ownership, but not much hand holding. The direction is clear. The expectation is that you can think for yourself and build things properly.


Your work includes:

• Writing backend logic in TypeScript on AWS Lambda

• Building services across the data pipeline

• Working with S3, DynamoDB, SQS and other AWS services

• Improving performance and cost efficiency

• Keeping the architecture clean and understandable

• Writing code that is easy to read, test and change

• Collaborating with frontend engineers working in Angular

• Contributing to technical decisions as the product grows


Fullinfo values clarity over cleverness and structure over shortcuts.


Requirements

You bring:

• 5 plus years of backend engineering experience with Node.js/Nest.JS

• Real experience with AWS serverless services

• Hands on experience with Lambda, S3, DynamoDB and SQS

• A strong instinct for clean architecture and maintainability

• Comfort working in a small remote team with minimal process

• Business level English

• You are based within 3 hours of Central European Time or are located in LATAM


Conditions

• 12 month B2B contract

• Up to $80.000

• Fully remote work

• Long term project with unlimited extensions


The hiring process includes an intro call, a technical assignment and a final conversation with the engineering team.
