About the opportunity
We are looking for an exceptional Senior Software Engineer to join our Backend team. This is a unique opportunity to join a fast-growing company where you will get to solve real customer and business problems, shape the future of a product built for Bharat and build the engineering culture of the team. You will have immense responsibility and autonomy to push the boundaries of engineering to deliver scalable and resilient systems.
As a Senior Software Engineer, you will be responsible for shipping innovative features at breakneck speed, designing the architecture, mentoring other engineers on the team and pushing for a high bar of engineering standards like code quality, automated testing, performance, CI/CD, etc. If you are someone who loves solving problems for customers, technology, the craft of software engineering, and the thrill of building startups, we would like to talk to you.
What you will be doing
- Build and ship features in our Node.js (and now migrating to TypeScript) codebase that directly impact user experience and help move the top and bottom line of the business.
- Collaborate closely with our product, design and data team to build innovative features to deliver a world class product to our customers. At company, product managers don’t “tell” what to build. In fact, we all collaborate on how to solve a problem for our customers and the business. Engineering plays a big part in it.
- Design scalable platforms that empower our product and marketing teams to rapidly experiment.
- Own the quality of our products by writing automated tests, reviewing code, making systems observable and resilient to failures.
- Drive code quality and pay down architectural debt by continuous analysis of our codebases and systems, and continuous refactoring.
- Architect our systems for faster iterations, releasability, scalability and high availability using practices like Domain Driven Design, Event Driven Architecture, Cloud Native Architecture and Observability.
- Set the engineering culture with the rest of the team by defining how we should work as a team, set standards for quality, and improve the speed of engineering execution.
The role could be ideal for you if you
- Experience of 4-8 years of working in backend engineering with at least 2 years of production experience in TypeScript, Express.js (or another popular framework like Nest.js) and MongoDB (or any popular database like MySQL, PostgreSQL, DynamoDB, etc.).
- Well versed with one or more architectures and design patterns such as MVC, Domain Driven Design, CQRS, Event Driven Architecture, Cloud Native Architecture, etc.
- Experienced in writing automated tests (especially integration tests) and Continuous Integration. At company, engineers own quality and hence, writing automated tests is crucial to the role.
- Experience with managing production infrastructure using technologies like public cloud providers (AWS, GCP, Azure, etc.). Bonus: if you have experience in using Kubernetes.
- Experience in observability techniques like code instrumentation for metrics, tracing and logging.
- Care deeply about code quality, code reviews, software architecture (think about Object Oriented Programming, Clean Code, etc.), scalability and reliability. Bonus: if you have experience in this from your past roles.
- Understand the importance of shipping fast in a startup environment and constantly try to find ingenious ways to achieve the same.
- Collaborate well with everyone on the team. We communicate a lot and don’t hesitate to get quick feedback from other members on the team sooner than later.
- Can take ownership of goals and deliver them with high accountability.
Don’t hesitate to try out new technologies. At company, nobody is limited to a role. Every engineer in our team is an expert of at least one technology but often ventures out in adjacent technologies like React.js, Flutter, Data Platforms, AWS and Kubernetes. If you are not excited by this, you will not like working at company. Bonus: if you have experience in adjacent technologies like AWS (or any public cloud provider, Github Actions (or CircleCI), Kubernetes, Infrastructure as Code (Terraform, Pulumi, etc.), etc.

60 Decibels is a tech-powered impact measurement company that makes it easy to listen to the people who matter most. We've been in business as an independent entity since early 2019, when we spun out of the global Impact Investor Acumen.

We do it quickly and without the fuss typically associated with measuring social impact. Our research assistants speak directly to customers to understand their lived experience; and our team turns all this data into benchmarked social performance reports, with accompanying insights, to help our clients demonstrate and improve social performance.
