Life at Nesto Cloud

At Nesto Cloud, you'll build the future of lending alongside some of the country's top developers, AI engineers, and mortgage experts. You'll work with a modern tech stack and AI-driven development frameworks designed to help you innovate, grow your skills, and accelerate your career.

About the role

Since the beginning, we've been committed to creating a modern and cloud-native tech platform (based on Google Cloud) that adheres to the industry's highest development and operation standards. Our front-end is written in TypeScript with React, and our back-end is in Go, consisting of loosely coupled Docker-containerized microservices communicating via RESTful APIs and pub-sub queues, and isolated behind different API gateways. These containers are orchestrated using Kubernetes and monitored with APM via Datadog. Our CI/CD pipelines are automated using GitHub Actions, ArgoCD, and our own open-source config management tool Joy. All infrastructure configuration is managed using Infrastructure as Code via Pulumi (similar to Terraform, but using a rich and extensible programming language and API, in our case, TypeScript), ArgoCD and Crossplane.

We strive to implement the best emerging DevOps practices, such as GitOps, Internal Developer Platforms, and Infrastructure as Code. We believe that DevOps goes beyond the mere automation of pipelines; it should encompass all areas of the business, empowering its actors and stakeholders to actively contribute to the organization's overall success.

We are looking for a passionate Senior Platform Developer who shares our core principles and wishes to join our dedicated Platform team. This person must have the technical and interpersonal skills to help us take our Internal Developer Platform to the next level, enabling rapid business growth and sustainable scalability. We're open to different levels of seniority, and we're proud to have a transparent career ladder where your progression within the company is clear and tangible, based on your aspirations.

What you'll be doing

You will apply software engineering principles to platform development, focusing on building the tools, infrastructure, and developer experience that empower every team at nesto to move fast and with confidence.

• Internal Developer Platform: Shape and build our Internal Developer Platform (IDP), continuously improving developer productivity, scalability, and sustainable growth.
• • Work closely with different internal consumers of our value stream to understand their respective tools and processes, in order to define, develop, and deliver efficient solutions adapted to their needs.
  • Build and evolve our IDP in the form of Golang CLIs and microservices, and observability tooling.
  • Contribute to improving the developer experience at nesto, identifying gaps and expanding platform capabilities to meet the needs of a growing engineering organization.
• Infrastructure & Automation: Create sustainable infrastructure and automation practices that eliminate bottlenecks, reduce toil, and position the platform for long-term scale.
• • Enhance our infrastructure automation (Golang, Pulumi, TypeScript, Crossplane) and contribute to maturing our cloud infrastructure to ensure it is secure, compliant, and cost-effective.
  • Maintain and optimize our CI/CD pipelines (GitHub Actions) and deployment processes (Kubernetes, Helm, ArgoCD).
  • Remediate security issues raised by tools and advisors.
• Collaboration & Platform Ownership: Work closely with development teams to integrate platform considerations and contribute to system design, capacity planning, and architectural conversations.
• • Take part in development with our Back-End team, bringing a platform perspective to shared technical challenges.
  • Monitor our platform alongside all fellow engineers, remaining open-minded and on the lookout for new practices and technologies.
  • Share knowledge and best practices for platform engineering, infrastructure, and developer tooling across development teams.

Who we're looking for

• You have 5+ years of development experience, ideally with Golang and TypeScript/JS.
• You have 5+ years of experience in cloud infrastructure with any of the top cloud providers, ideally GCP.
• You are familiar with CI/CD, Kubernetes, Docker, Helm, Infrastructure as Code (Terraform/Pulumi), and networking.
• You're comfortable using AI tools to boost your productivity. We actively use and encourage the use of AI in our day-to-day work, but we hold ourselves accountable for the quality, security, and correctness of whatever we ship, AI-assisted or not.
• You thrive on being part of a team and collaborating with people from diverse backgrounds.
• You enjoy both the big picture and the small details, and have a deliberate, long-term approach to systems thinking.
• You have a passion for continuous learning and enjoy sharing knowledge with others.
• Ideally, you have knowledge or interest in security best practices such as vulnerability scanning and intrusion detection.

The Reward

• The A-Team: Work alongside high-performing talent in the industry.
• Accelerated Growth: The slope of your learning curve here will be vertical. You will touch more production systems in one year than you would in five years at a bank.
• Top-Tier Coverage: Premium benefits plan fully paid by nesto, including comprehensive insurance and unlimited access to telemedicine and mental health services for you and your family.
• Rest & Recharge: 4 weeks of vacation to ensure you stay at peak performance.
• Best-in-Class Tools: Access to the resources and tech you need to execute without friction.
• Working framework: The environment that makes you productive and enables teamwork (Hybrid model).

Diversity and Inclusion

At nesto, we believe that creativity and collaboration are the result of a diverse team. We are committed to fostering a culture of diversity, equity, inclusion, and belonging, and we strongly encourage women, people of color, LGBTQIA+ individuals, and individuals with disabilities to apply. We are committed to creating a workplace that is inclusive and welcoming to all.
