Do you thrive on creating reusable frameworks and APIs that make entire engineering teams more productive? If you’re excited to help build the backbone of AI-driven solutions in Multifamily real estate, read on…

Travtus is transforming Multifamily real estate operations with AI-powered SaaS solutions. Our platform automates and enhances Multifamily building operations, boosting efficiency, staff retention and improving resident satisfaction with data-led decisions. We’re on a mission to modernise property operations with our everyday AI platform built for the Multifamily real estate industry.

As a Platform Software Engineer, you will focus on building the shared platform layer that underpins our entire AI solution suite. You will create frameworks, services, data pipelines and APIs that enable high-volume data products. Whether you are implementing business logic or enabling seamless integration with both internal and external systems, your work is critical to the success of the business. With direct impact on all products, your work helps to accelerate development and ensure reliability, scalability, and security of our common platform. You will be collaborating closely with other engineers to evolve our core platform, introduce best practices, and mentor peers in building industrial-strength services. Most of all, you will enjoy working with a great team and be passionate about the work you do.

Our Platform Software Engineers work across the technical stack, designing and implementing the solutions that enable Product Engineers to create new applications.

• Architect, develop, and maintain shared services, frameworks, data pipelines, and APIs in Python, enabling reuse and speeding up feature delivery for product teams.
• Design scalable systems for data ingestion, storage, and processing, supporting multi-tenant requirements and common analytics needs.
• Build frameworks that streamline integration with third-party APIs and internal microservices, abstracting complexity from product engineers.
• Lead initiatives to standardise and document platform interfaces, promoting consistency and discoverability for developers.
• Embed security, observability, and compliance into all shared services and workflows.
• Collaborate with application teams to identify gaps in the platform and prioritise new features or improvements.
• Drive adoption of best practices in testing, CI/CD, and platform monitoring.
• Mentor engineers in platform development, code quality, and the effective use of shared services.

We are looking for an enthusiastic individual with a strong passion for technology who thrives on meeting challenges collaboratively and is passionate about using AI.

• Extensive experience developing backend software, APIs, and reusable components in Python.
• Experience architecting and scaling SaaS solutions using AWS components (Lambda, API Gateway, RDS, S3, Cognito, etc.).
• Solid understanding of API security.
• Enthusiasm for driving developer productivity through great platform and framework design and documentation.
• Experience in data platform engineering (pipelines, transformation, real-time processing).
• Familiarity with microservices and SOA, including event-driven architectures.

• Whilst AI development or integration experience is not essential, you should have more than an interest in AI and how it can be applied effectively in your work.
• TDD and/or contract testing for platform reliability, CI/CD, and platform monitoring.

We are a dedicated team, working in a truly collaborative style, where everyone is heard and brings something valuable to the conversation. Constantly pushing boundaries to create groundbreaking solutions for our customers. We are fundamentally challenging the way one of the largest industries in the world operates, and our commercial success pays testament to the skill, commitment and passion that our team displays every day. Working together in person fuels our best ideas and innovations, which is why all team members spend at least three days a week in our London office.

• Be part of a growing, mission-driven startup with global ambitions
• Exposure to cutting-edge AI technology in a practical, high-demand sector
• Collaborative, fast-paced team culture with space to innovate and grow
• Hybrid working model with a modern London office (Liverpool Street, 3 days a week)
