HotelTonight makes it remarkably easy to book great hotels at amazing rates on your mobile device for tonight, tomorrow and beyond. Our goal is to be the premier and most loved way to book a place to stay and we’re looking for a Senior Software Engineer to help do just that.
We’re seeking teammates who want to set the standard, question the status quo, and want to keep learning. Part of the greater Product Development team, the Core Services team focuses on the back-end services and infrastructure that support iOS and Android features of the consumer facing app. We are a team of builders; we like to solve problems, take action, and work collaboratively with others to get stuff done.
This is a great opportunity for an engineer who is passionate about the product, thinks of the users, and wants to utilize the latest technologies to deliver industry-changing products. HotelTonight now allows users to book a hotel up to 100 days in advance - an exciting expansion for many reasons, but it’s also a significant change to our backend infrastructure. This means there are some big, challenging projects ahead for you and the rest of the Platform team to tackle.
You’ll have an immediate impact, ensuring that our APIs, infrastructure, and internal tools create a world class user experience and help HotelTonight on its mission to become the only hotel booking app you need on your phone.
The Wire Team plays a pivotal, yet behind-the-scenes, role at CAST AI. While they may not directly manage the products that customers purchase, the value they create is indispensable for making all of CAST AI's offerings functional and user-friendly.
The team develops a wide array of user-facing features that contribute to a fully realized platform. This includes designing robust authorization and authentication flows, managing user and organization accounts, as well as implementing notifications and audit systems, among other tasks. Furthermore, they create frameworks and tools that enable other internal teams to seamlessly incorporate these capabilities into their own products.
In addition to these tasks, the Wire Team is also responsible for implementing enterprise-level Single Sign-On (SSO) integrations as a self-service feature. They work on integrating billing systems with various cloud marketplaces and oversee the management of platform entitlements.
In essence, the Wire Team's efforts are crucial to the very existence of our platform. Their mission is to elevate the user experience, regardless of whether the customer is a small startup or a large enterprise.
How Do We Operate? At CAST AI, we specifically seek out Software Engineers rather than Software Developers. This distinction is not merely semantic; it underscores a profound difference in responsibilities and expectations. Let's delve into what sets the two apart.
A Software Engineer is responsible for overseeing the entire lifecycle of a system, starting from its conceptual genesis to its continuous delivery of value to customers. When a high-value feature is identified and properly prioritized, an engineer takes ownership. The task entails not just coding but also meticulously reviewing the technical architecture, design, and feasibility of the feature. Beyond functional aspects, we pay heed to:
Testability Adaptability Performance and Scalability Deployment and Compatibility Debugging and Operational Management. Throughout this comprehensive process, collaboration is key. While engineers are accountable for end-to-end delivery, they are also encouraged to consult with peers to arrive at the most effective solutions. The capacity to work both independently and as part of a team is essential.
To expedite delivery, we have devised a suite of proprietary tools that assist us in various aspects of development. Engineers periodically switch roles to write automated end-to-end tests, optimise our GitOps-enabled continuous integration and continuous deployment (CI/CD) pipelines, or fine-tune our observability stack. We even have a rotation for passive on-call duties to promptly address any issues that arise within our codebase.
It's worth noting that we do not employ separate DevOps or QA roles within our engineering team. Self-reliance is vital: we automate everything and construct our own tooling. Therefore, a broad systems-oriented perspective - going beyond mere software development - is indispensable for success within our team.
Our mantra is straightforward: we build it, we test it, we ship it and we operate it.
Here are some of the tools we use daily: GoLang is our language Kubernetes is our core product AWS, GCP, and Azure are the clouds we operate Postgres and cloud object storage for persistence GCP PubSub for messaging GRPC and REST APIs We use GitLab CI with ArgoCD as our GitOps CD engine Prometheus, Grafana, Loki, and Tempo for observability Deployment charts are written in Helm. Having experience with these tools is not a strict prerequisite for the ideal candidate, but it does offer a competitive edge.

About us:
All in Bits (AiB) aims to create a more transparent and accountable world through open-source software that enables permissionless innovation and borderless transactions. Our technology empowers builders to launch sovereign blockchains and decentralized applications (dApps) that are secure, scalable, and interoperable.
As a core contributor to the thriving Cosmos ecosystem, AiB engineers pioneered the first-ever Proof-of-Stake network and built the core infrastructure that powers Cosmos today including Tendermint Core, Cosmos SDK, and Inter-Blockchain Communication (IBC). From creating and funding to engineering and marketing, we prioritize simplicity and minimal production to build technological solutions that endure.
AiB is committed to upholding core Cosmos values of transparency, accountability, and decentralization. That’s why we support the creation of the Decentralists DAO for the Cosmos Hub to move all operations on-chain, starting with engineering. By establishing the Decentralists Engineering Team (DET), we aim to advance core components of the Cosmos tech stack and encourage open dialogue, decision-making, and innovation.
How we work:
We focus on talent rather than location to hire the very best person for every role. Open communication is vital, and we use the best tools to collaborate efficiently. Everyone has the autonomy to create their best work, which we reward with unlimited growth potential. AiB is remote-first, and to support your working life, we offer carefully considered benefits and hold regular team and company-wide meetings to encourage collaboration and interaction between teams.
You have flexibility to work the hours best suited to your lifestyle; as long as you deliver consistent quality work, the sky's the limit!

Nice to have:
We're building a unified developer experience to help software teams move faster and stay focused on achieving their goals. Over the past decades, software development has grown in importance inside organizations and with it there has been a Cambrian explosion of tooling. While each tool is great at what it does, they live in their own silos and weren’t built to work together. These silos lead to disconnected workflows, context switching, and difficulty finding information. Our vision is to build a better way to get work done. Summon brings together your tools and data into one blazingly fast, native experience. We’re just getting started and our ambition is bold: build the best platform for software teams to get their work done. We love what we do and are motivated by working on a product we love using ourselves. You would have an immediate impact as a builder to influence engineering and the direction of the product. You join as a founding engineer and have full ownership working closely with our founders and a team of super talented developers.
Who we’re looking for
We are looking for a full-time backend engineer. Our ideal candidate has 5+ years of experience building event driven microservices or service oriented architectures and has built most facets, if not all, in a "twelve-factor" app. Preference is for real experience (2+ years) in our primary language of Golang, but other languages are considered when able to quickly pick up new technologies. Additional experience in integrating with 3rd party systems, event-driven architecture, databases, and cloud services (AWS, GCP, etc) are important.
You will directly influence how and what to build, and must be comfortable collaborating on the architecture, code, product, etc as we have a strong culture of devops as well as being technically curious, thoughtful and purposeful in what we build. We value deploying frequently with well-written, maintainable, instrumented and tested code to a kubernetes cluster.

Why join us?
We love what we do: designing and building great products. But our work isn't the only thing that defines us. We're not trying to create some semi-cult to get people to work here. We simply enjoy working together and building useful and beautiful software for our customers. We’re a venture-backed startup and are looking for someone who is excited about the early stages of building a product and having a tangible impact on the company’s success. You would join a group of repeat founders. We have founded startups backed by top Silicon Valley VCs. While getting huge amounts of venture capital has its advantages, it also puts a company on a very narrow success path. We want to do it a little differently this time. Where raising money and growth is balanced with the goal of being default-alive and capital-efficient. Which gives us optionality and lets us build the company we want to build over the long run.
