About the Role:
As a Senior Software Engineer based in Mexico, you will play a pivotal role in designing, developing, and delivering high-quality software solutions on a small team designing and implementing new features for two new products (< 2 years old). You will be expected to handle both frontend and backend development.
Minimum Qualifications:
- Strong Node.js/JavaScript — everything is Node (20/24). Notably must be comfortable with both module systems.
- AWS serverless architecture — Lambda, SQS, S3, Secrets Manager, DynamoDB API Gateway. Both APIs are built on Serverless Framework v4 with serverless-offline for local dev.
- PostgreSQL with Knex + Objection.js — both products use this exact ORM stack. Comfort writing and rolling back migrations is a real day-to-day skill here.
- React + Next.js 14 —Solid React with Next.js fundamentals with form-heavy, table-heavy CRUD UI experience.
- Comfort working within an internal design system — including debugging CSS specificity/source-order issues rather than reaching for a rewrite.
- Fluency in English and Spanish,
both written and spoken.
Preferred Qualifications:
- SOAP and XML processing — Both products interface with existing internal and third-party systems using SOAP interfaces with XML.
- Document and image handling — TIFF/PNG processing, PDF generation.
- Express —both inside Lambda (via serverless-express) and on EC2 (the SOAP/PRIA service).
- Jest for unit and integration; Cypress for the UI.
- Experience working in an Agile/Scrum development environment.
- Experience using AI coding tools
Responsibilities:
- Develop new features handling both the front end and back end development work.
- Collaborate with product managers, designers, and other engineers to define technical requirements and deliverables.
- Conduct code reviews and ensure adherence to coding standards, quality, and security guidelines.
- Collaborate on architectural decisions to align with long-term business goals.
- Stay current with e
