Staff Software Engineer (External APIs) with Bestow
Austin, Dallas$140k – $150k
1 year ago

Job Description

Who We Are

First thing you need to know; Bestow is not your typical insurance company. We’ve completely reimagined industry assumptions, and harnessed technology and big data to create life insurance products that aren’t just delightful to use but deliver on our mission: to make financial products accessible to more people than ever before.

Check us out at hellobestow.com

Who We’re Looking For

“Innovative” and “disruptive” can be overused words. But at Bestow, it isn’t jargon, it’s an everyday rally cry. We are rewriting the rules of the 400-year-old, $7 trillion life insurance industry, serving communities who have been underserved in the past, and we believe the future is a bright one.

So, if you’re excited by the idea of building something from scratch, working at a mission-driven company and fundamentally shaking up an age-old industry, please read on.

As a Staff Software Engineer on our Partner team you will lead development on external-facing APIs for our business partners. Much of the space is greenfield and will require making significant foundation decisions.

You take great pride in your craft and look for ways to improve our software and team effectiveness. You enjoy designing and documenting APIs and empathize with the developers using them. You have prior experience designing and implementing distributed systems. You balance concerns of maintainability, reliability and scalability with the need to deliver results. Less experienced engineers look to you for guidance and feedback on their work, and you’re thrilled to provide it.

Bestow software engineers are great teammates. You are willing to collaborate with other software engineers, product managers and designers. You also have exceptional written and verbal communication skills.

Ensuring a Robust Software Platform

Great software is more than product features. It simultaneously considers non-functional concerns like security, maintainability and extensibility. You will:

Take ownership over issues arising from previously delivered features; Ensure the security of our applications through participation in external penetration tests, threat modeling and security-focused code review; Use modern extensibility methods such as feature toggles; Automate routine developer workflows such as environment setup.

Fostering Best Practices

We might be small but we’ve got big ambitions. Folks joining the team will be defining our software engineering culture. You are someone that strives to build a premier engineering organization.

Measure quality metrics such as test coverage and gradually improve themLeave code in a better place than it was when you started; Encourage automation and continuous improvement.

A Little About You:

6+ years of back end software development experience; Professional experience with Python 3; Experience with statically typed languages (C#, Java, Golang, Rust, etc.); Professional experience with a relational database like PostgreSQL; Experience using Docker/Kubernetes for software development and deployment; Experience designing and documenting APIs (Protocol Buffers, RAML, Swagger, OpenAPI, etc.); Experience with distributed systems and microservices; Advocated for Continuous Integration/Continuous Delivery (CI/CD); Clear, concise written and verbal communication; A desire and willingness to learn; Initiative and motivation to make things happen.

What We Can Offer To You:

Competitive salary; Generous PTO; Flexible schedule and work/life balance; 100% company-paid health, dental, and vision insurance; Choose your own computer setup (Mac or PC); Office snacks and weekly team lunches; Team building events and activities.

  • We’re entirely hosted on AWS and make extensive use of many of their services (over 30 at last count!)
  • 15+ containerised microservices running in ECS (we’re open to exploring moving to Kubernetes in the future if appropriate). Our services talk protocol buffers over HTTP and are discovered with Consul.
  • Dozens of event driven serverless functions running on Lambda, some running as APIs behind API Gateway and others as Step Functions
  • Dockerised batch compute workflows
  • NoSQL databases (predominantly DynamoDB and ElasticSearch)
  • Serverless analytics data lake backed by S3 using Athena (PrestoDB)
  • Terraform and Serverless Framework to manage our infrastructure as code

Backend Go Developer with Geckoboard
London, United Kingdom£40k - £61k
2 years ago

Job Description

At Geckoboard we help businesses use their data to align their teams on the metrics that matter most to them. We’ve been busy reimagining the way our customers get their data in Geckoboard and have a lot of interesting and creative work to do to shape their experiences. Right now, we’re looking for curious problem solvers to help us on this journey.

What are we working on?

We’ve completely rebuilt how data gets into Geckoboard from third-party APIs, thanks to a query planner that’s written entirely in Go. Our query planner takes in the metrics that a customer would like to track, and produces a plan for how to fetch and transform those metrics from a third-party JSON API such as Zendesk, Intercom, Google Analytics, etc.

We’re now working on extending this platform and building various microservices for tracking our customers’ rate limits and scheduling metric refreshes in the most efficient way possible. We’re also creating a caching engine that ensures we don’t waste precious API calls on data that we know hasn’t changed since last time.

The team are also in the middle of splitting up our existing REST APIs into gRPC microservices with segregated data stores. Which is a huge opportunity for us to rethink some of the fundamental assumptions about Geckoboard’s data model and how we can re-architect our systems for greater reliability and to enable us to ship with more confidence.

We don’t expect you’ll have worked on all of these kinds of projects before, but if they take your fancy and you’re excited about working on distributed systems and database technologies at scale, we’d love to hear from you.

As one of our Backend Go Developers:

  • You’ll be writing in Golang on a day-to-day basis.
  • You will help architect, design, and build Geckoboard’s data pipeline.
  • You’ll maintain and optimise our existing infrastructure and services.
  • You will get involved in the prioritising and evaluation of our work.
  • You’ll pair with team members and get involved in code reviews.

Joining us in our London office, you’ll be working alongside a growing team of empowered engineers, with a focus on building a high quality product our customers love, work life balance and personal development.

Keen to hear a bit more? Carlos, one of our Backend Go Developers has shared a little about what it’s like working with the team, what an average day looks like and more in an interview on our Blog: https://medium.com/geckoboard-under-the-hood/working-at-geckoboard-as-a-go-developer-e73855bd0dd8

The Geckoboard Story

Thousands of businesses use Geckoboard to build live TV Dashboards that focus teams on what matters. We take the complexity out of connecting data and make it simple for anyone to understand key metrics at a glance. We have pre-built integrations with 60+ tools including Google Analytics, Salesforce, Zendesk, Intercom and Google Sheets and our customers include Marketo, Slack, and Skyscanner.

In our mission to make data useful, our growing team of 40+ is headquartered in London and span across eight time zones - from Mumbai to London, San Francisco to Hawaii and more. We’re always looking for people with diverse backgrounds who bring unique perspectives and skills to join our team and in return we constantly strive to ensure that we offer the most encouraging, inclusive, and efficient environment possible.

We don’t just pay lip service to work-life balance, we actively and strongly encourage it. Flexible working hours and the ability to regularly work from home lets you work in a way that fits you and your family. We see our contractual obligation to offer 25 days of paid holiday as a minimum for everyone in the organisation, not a limit.

We actively contribute to professional development, courses, conferences, and books. Our Engineering & Product team also run fortnightly “Innovation Wednesdays”, where everyone has complete freedom to work on anything that interests them, from contributing to open source, to learning a new skill, or improving our internal tools and processes.

And, don’t take our word for it, see what the team say about the projects they work on: https://medium.com/geckoboard-under-the-hood and their experience of working with us on Glassdoor: https://www.glassdoor.co.uk/Reviews/Geckoboard-Reviews-E878996.htm.

Golang Developer for PaaS MVP - Part-Time with Zweitag GmbH
Berlin, Germany€50k - €70k
11 months ago

Job Description

We are looking for a Golang developer who helps us develop an MVP for a nice Infrastructure as Code project. The MVP consists of a command-line application and a REST API for managing AWS cloud infrastructure in Golang. The project is running only for a few weeks, so you’ll have the opportunity to contribute a cool project right from the start!

tl;dr

  • Develop a Golang command-line application and a REST API
  • Strong focus on internal and external software quality
  • Ambitious project context in the AWS cloud (Infrastructure as Code, High Availability, a high degree of automation)
  • For 10 to 16 hours per week
  • We speak English and German
  • AWS cloud / Infrastructure as Code / Part-time / Freelance

Project Background

We are developing the prototype of an innovative product for managing cloud infrastructure. It is all about running web applications in the AWS cloud in an easy-to-use, reliable, and automated way. Our users should be able to create and maintain the resources that they need without any external help. Behind the curtains, there is a framework that manages those resources in the AWS cloud with Terraform. This concept aligns with the Infrastructure-as-Code principle, which aims at providing documented and managed-like-source-code infrastructure definitions. We set a strong focus on economic factors, in that it should be viable to run both small and large applications and to scale those applications with high load and amount of users. The platform should be highly available and self-repairing – nobody should be on-call and responsible for fixing server deployments in the middle of the night. We have already validated a solution for creating and managing such an infrastructure, and we are in the process of bringing it to life.

The Task at Hand

The platform’s user interface is a command-line application which talks to the REST API, which we also develop. We want to implement these tools in Golang, and engineering has just started. We have a strong focus on software quality: in the end, we want to have a well-designed, robust software architecture with clear responsibilities and interfaces. The product should be automatically testable and maintainable for an extended period. An important factor will be integrating several data sources to deliver the right information to the user at the right time. The challenge lies in the heterogeneity and complexity of the data sources (for example, Terraform and AWS). It is also important to us that the product is intuitively usable: it should transform hosting infrastructure from a bothersome task to something fun. To achieve this, we want to gather user feedback and act on it iteratively.

Your Qualifications

You should have considerable experience with Golang and see yourself on an intermediate-to-senior level. In particular, you should engage with topics such as software architecture, testing on unit/integration/end-to-end level, and picking the right frameworks and libraries. You are also excited about clear software architecture and clean, well-maintainable code. We really care about this! ;) If you’ve got experience with infrastructure tools such as Terraform, Docker, Kubernetes, or cloud platforms such as AWS or Azure – that’s a plus, but we don’t expect you to know everything. And you won’t have to dive deep into all those topics (depending on your personal preferences, of course). There are more bonus points if you know how to integrate 3rd party CLI apps in a stable and reliable way.

The Scenario

You’re living in Berlin, Potsdam, or somewhere nearby, and you have one to two days per week to spare. The project is sponsored by a company for digital products in Münster (Zweitag). However, there is no need to travel there because you work together with a team member who lives in Berlin. The current project is projected to take six months. If it all works out fine, we can see you being invited to work with us for longer. 🙂
