We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges.

About the role:

You’ll collaborate closely with other engineers, our Product team, and our Data team to design, build, and deliver high-quality technology and customer experiences.

Our current stack includes Python, Django, Typescript, React, React Native, and AWS serverless technologies (Lambda, S3, DynamoDB, API Gateway, SNS/SQS).

Our engineers own their work end-to-end. You’ll work across frontend, backend, and platform infrastructure, with learning opportunities throughout your time to expand your skills.

• Design, build, and deliver software that supports our client’s growth and mission
• Collaborate with engineers, product managers, and data specialists to shape solutions
• Contribute across the tech stack – frontend, backend, and infrastructure
• Take ownership of code quality through testing, code reviews, and documentation
• Work in agile sprints, supporting requirements gathering and estimation

Requirements:

• Solid programming skills, with experience delivering software in production environments. Experience with the primary languages in our stack (Python, Typescript)
• Strong grasp of software engineering practices: version control, code review, test-driven development, software architecture, and pair programming
• Comfortable working across multiple technical areas, from frontend to backend and infrastructure
• Clear communicator, able to adapt technical detail to different audiences
• Previous experience contributing to complex software projects
• Previous experience working with both relational and non-relational databases (we use PostgreSQL and DynamoDB)
• Experience working in agile software development teams
• A track record of delivering high-quality, maintainable software
• Pragmatic – understand the trade-offs of software delivery

What`s in it for you?

• Strong community: Work alongside top professionals in a friendly, open-door environment
• Growth focus: Take on large-scale projects with a global impact and expand your expertise
• Tailored learning: Boost your skills with internal events (meetups, conferences, workshops), Udemy access, language courses, and company-paid certifications
• Endless opportunities: Explore diverse domains through internal mobility, finding the best fit to gain hands-on experience with cutting-edge technologies
• Flexibility: Enjoy radical flexibility – work remotely or from an office, your choice
• Care: We’ve got you covered with company-paid medical insurance, mental health support, and financial & legal consultations
