We are looking for an experienced Senior Software Engineer (Integrations) to contribute to PriceLabs' ambitious plans. We have an existing product that's being used by thousands of customers worldwide and are looking to upgrade our design and launch new features that will serve customers worldwide.
What you will learn at PriceLabs:
Scaling:
- We currently exchange tens of millions of prices between us and our partners multiple times every day! As we continue to grow, designing our architecture to keep working seamlessly is going to need a lot of teamwork
- Doubling in size every year brings unique scaling challenges. Our product started with one single server doing everything needed, but over time we've created a fairly distributed architecture of micro-services. Ensuring our systems continue to provide the same level of service with twice the number of customers next year teaches us (and you!) forward thinking!
Fundamentals:
- We have a very strong emphasis on fundamentals - writing code in strict memory requirements, setting up a server from scratch, being able to use open source services (like nginx, mysql, linux servers, redis, rabbitmq) to get the best performance out sets our team up for long term success.
- Implementing to the standards of operating systems, working in a thread safe/unsafe environment.
- Understand how servers interact with each other in a data center. How does nginx and unicorn power the communication for our APIs.
Customer-centric engineering:
- Making a product that needs to work for both single home-owners as well as enterprise customers to property management businesses - we're on a journey towards design and process thinking to ensure systems are easy to use. Expect strong collaboration with customer facing, design and data science teams!
New products:
- We have a lot of ground level infrastructure available for us to build new products for both our customers and our industry partners to use. Architecting these systems from scratch is a joy in itself (our team has done this a few times!)
Amazing team:
- Our engineering team is very focused on getting things done, and getting them done the right way so the last long! Write better code everyday, solving customer and co-worker pain points, and learning from our peers is what keeps us going!
Responsibilities:
- You will work with Ruby, we are a RoR platform so understanding how ruby interacts with database would be ideal but not preferred.
- Build new integrations with property management systems (PMS) and also maintain existing ones.
- Understand nuances of downstream systems and design and architect your solution keeping in mind third party systems
- Talk to existing PMS and understand what new features can be incorporated and what existing features need to be updated.
- Fix issues that break and keep a track of daily status and understand inefficiencies.
- Engage with PMS partners and optimise the existing pipeline.
- Continuous improvement to our web stack, set standards, automate mundane tasks
Requirements:
- 4+ years experience in back end web development and understanding Ruby would be great but not mandatory.
- You should be comfortable working with git, visual studio code(or any IDE that you prefer) and test your own code thoroughly before making a PR.
- Ability to architect and develop systems so it can connect seamlessly with PMS and third party systems.
- Ability to understand Message queues and how a pub-sub system works with multiple servers
- Experience in building distributed systems that integrate with RESTful APIs and SOAP XMLs.
