Senior Software Engineer (Go) with LevelSponsored
Remote
$110,000 to $115,000 a year
3 weeks ago

Job Description

About Us

Level (https://level.io) is an exciting startup that will soon be entering the remote monitoring and management space. We’re fans of the “Lean Startup” methodology and after many customer conversations, we’re almost ready to launch our MVP. We feel like this space is stale with older products that offer a poor user experience. Our product features a simple interface and exciting technology that none of our competitors are utilizing.

We’re backed by the founders of a very successful Managed Service Provider (MSP). They have extensive experience in the IT space and have proven invaluable in helping us validate that we are building the correct thing.

Salary

$110,000 - $115,000

Level Senior Engineer Role

Level is building a modern remote management and monitoring solution. We are a small team that is well funded and close to launching to our early access customers. We are searching for a strong, multi-talented individual contributor who is comfortable with systems-level programming and networking who can contribute to our agent, written in Go.

Must-Haves

  • Deep knowledge of a systems language like C, Rust, or Go.
  • Not afraid to dig into an RFC. Low-level internals excites you, rather than scare you away.
  • Experience with system-level APIs in Windows (win32), macOS, and/or Linux.
  • Excellent written communicator.
  • Willing to learn and work with Go.

Nice-to-Haves

  • Significant WebRTC experience. You have built something with Pion.
  • C/Objective-C experience, sometimes using system APIs means writing bindings to use in Go.
  • Video encoding experience. You have worked with H264 and understand the spec.
  • Building cross-platform libraries, our Go agent compiles to Windows, Darwin, and Linux on a variety of architectures.

Things you might work on

  • Building a cross-platform interface to query the active processes on an OS and transmit them over a WebRTC Data Channel to our web app.
  • Working with libav to create a custom h264 encoder to reduce the latency and bandwidth of streaming a device.
  • Creating a system tray GUI for the agent.
  • Securely allowing scripts to be executed against a machine and piping the results over a WebSocket connection.

Why you might want to work with us

  • We are a small, fully remote engineering team, and there are no layers of bureaucracy. You can have a huge impact here.
  • We are very flexible with working hours, we don’t expect you to work a consistent block of time, we trust you to get your work done.
  • We are on the cusp of launching our MVP and starting to grow.
  • We will offer profit sharing so our small team will receive dividends on profits the company makes.

More About Us

We are a startup headquartered in beautiful downtown Asheville, NC. We are a small, close-knit team working to upend the RMM market with a new product. Our CEO and leadership team have done extensive product research and are focusing on traction channels to grow while the product is being built. Though we are a startup, our investors have given us a multi-year runway.

We have already made substantial progress towards an MVP. We need someone to come in and help finish our Go agent who is an experienced self-starter that can make an impact on our product development. We aren’t interested in someone that just wants to work down a list of pre-defined tasks. Our ideal candidate loves working on products and will help shape the direction of ours. We hope to launch within the next couple of months and want someone to come on this journey with us.

We really like the Basecamp philosophy and try to make sure that it doesn’t have to be crazy at work. We won’t ask that you work weekends, or late into the night. We don’t mind if you need to leave for an appointment in the middle of the day. We understand that software development doesn’t happen for 8 hours straight and don’t worry about counting time in the chair. We trust that given a fair timeline with a scope that you help us determine you will be able to deliver features. We are concerned with the end goal, not micromanaging you on the way there.

Pay

We’re looking for someone great, but are an early-stage startup. We are offering a rate of $110-$115k plus (eventually) profit sharing. We know you could make more elsewhere, but this is an opportunity to jump onto a startup that has the chance to grow quickly in revenue where our profit sharing will ensure you are compensated for the value you bring.

In the afternoon, you enter a deep work period and finish working on improving one of the provider’s mapping models. Once down with that work you jump on a zoom call with the rest of the team to discuss the challenges and next steps with the PoC the team is building in this sprint.

Castor EDC Logo
Site Reliability Engineer with Castor EDC
Amsterdam, The Netherlands
€60,000 to €80,000 a year
10 months ago

Job Description

Our true purpose at Castor

Castor is one of the leading platforms for data collection in medical research. We believe standardizing and reusing datasets is key to overcoming the healthcare challenges of the future.

How we operate

Our main Electronic Data Capture (EDC) application runs on a proven stack consisting of Ubuntu, Nginx, PHP and MySQL. For our cloud installations, we orchestrate these setups by using Terraform combined with Ansible for the server configuration management.

Due to the nature of processing medical data, we have clients in different regions across the globe, often with specific regulatory constraints around where and how their research data is stored. To meet these customer demands we combine both traditional as well as cloud-based hosting solutions.

Most of our clients prefer to run in Azure, but we’re using Google Cloud Platform for things like Kubernetes hosting of greenfield projects, blob storage for scalable file upload storage and their Key Management System (KMS) to further secure our data.

For our metrics we’ve begun standardizing on Prometheus and we’re moving towards Loki for log aggregation. We use PagerDuty for alerting, communicate via Slack and host our code on Github.

Why we’re growing our team

With our recent expansion have come new challenges, both in how we organize ourselves and in how we manage and scale our infrastructure in the future.

To further these efforts we have formed a Platform team consisting of SRE and Software Engineering, which we are now looking to grow with the addition of an additional SRE.

Additionally, due to the sensitive nature of medical data, Castor is certified for both ISO/IEC 9001 (quality) and 27001 (Information security). In addition, we have to adhere to a number of other regulations, including Good Clinical Practice (GCP) guidelines.

Our goal is to unite these requirements with emerging SRE practices around infrastructure as code and other principles to create a well designed and documented system, while still allowing us to remain flexible to change.

How you will contribute

Our absolute commitment to patient data security and privacy informs our vendor selection with certified datacenter and cloud providers. To achieve real impact in medical research, Castor needs to operate security around the world.

Historically, our production platform has run on top of managed hosting services. This model doesn’t scale well for our global, international footprint, which is why we are currently expanding our in-house knowledge and transitioning to Infrastructure-as-a-Service providers.

As a Site Reliability Engineer, you’ll have the ability to shape our operations and continuously deliver a working product. Working very closely with the development teams, you’ll collaborate in supporting and structuring our efforts around automation, observability and security. With your help we plan to scale the Castor platform to the next level.

Some things we worked on recently

Whilst there are many operational challenges as we continue to grow and scale at Castor, our Platform team has made great improvements to a variety of our systems already. To give you some examples of what we achieved last month:

  • Migrated our DNS to AWS Route53
  • Set up automatic documentation pipelines using MkDocs
  • Moved our CI/CD pipelines from Jenkins to CircleCI
  • Built a key-service on AWS Lambda to store disk encryption keys off-site for an otherwise region-local setup

Your background

You have helped run web-facing services under production workloads and have experienced the challenges that come with maintaining and scaling these systems. Making and owning decisions about systems architecture together with your team is something you enjoy and feel comfortable with.

Qualities we’re looking for include:

  • A good grasp on how *NIX systems operate
  • The ability to evaluate and implement best practices for IT operations
  • A working knowledge of both cloud-native and traditional systems architecture and the trade-offs between them
  • Experience with a configuration management framework such as Ansible, Chef, Puppet or SaltStack
  • The ability and desire to work with a wide range of open source technologies
  • A strong privacy- and security mindset
  • Experience with some aspects of Observability and distributed systems: from monitoring, logging and metrics instrumentation to resiliency to failure
  • A good understanding of how relational databases operate
  • Experience with at least one programming or scripting language, preferably Python or Go(lang)
  • Knowledge that a list of skills and requirements doesn’t mean you have to tick every single box to apply ;)

How we say thank you

At Castor we truly live our core values, believing we can achieve anything with a healthy and happy team. With this in mind, we offer the following benefits:

  • Our own ‘Castor Burrow’ - brand new offices by Amsterdam Amstelstation
  • A competitive salary plus an annual company bonus plan
  • Employee Stock Option Programme incentive
  • 30 days annual leave plus 6 public holidays
  • An individual training and professional development budget
  • Flexible working with the opportunity to work from home 1 day per week
  • Meditation room with daily yoga, mindfulness and company subscription to Calm
  • Lunch and healthy snacks in the office every day
  • A new Mac or Dell laptop

$36,000 to $60,000 a year
2 years ago

Job Description

Please note: if you’re a recruiter or a development company, don’t waste your time contacting us. We are not interested for sure.

At Careibu we are aiming to build the best social care community by students in the world. We are looking for capable, creative developers who want to help us accomplish that goal.

About Careibu Careibu is all about social care. Through our platform, we connect students to people for help at home. Our students work as babysitters, home cleaners and elderly assistants. Careibu’s Dutch community consists of 32.000+ students and 13.000+ clients. In Juni 2018, we officially launched in the German market (Berlin). Our mission is to bring all generations in society together and provide students a social side job.

Careibu was founded in student accommodation by two sisters, Lotte and Anne. They have grown the business from their student rooms to a team of 13 people which continues to rapidly grow. Our head office is located in Amsterdam.

Things we are working on We’re still a small company with an even smaller development team (CTO, product owner, backend developer and 2 mobile developers). This means you will need to wear many hats in the beginning but it also means there are many interesting challenges ahead that you can specialise in if you like. Broadly we are: – Migrating from legacy platform which has some interesting challenges – Improving and expanding our iOS & Android applications

Our technology stack We still maintain a stack built in Angular 1 (web UI), PHP (backend) and MySQL (data), however we are incrementally migrating to a new technology stack based on a Golang backend with native mobile apps (Swift for iOS and Java for Android).

Since we develop, test, deploy and operate our systems, we do work with other technologies that automate such processes, like GitLab, GitLab-CI, Docker and AWS’s ECS & RDS.

You should apply if – You want to be involved in building a product that has a social impact – You’ve worked in GoLang or you are a senior backend dev willing and able to learn quickly – You don’t mind exploring our legacy PHP system & rebuilding functionality on our new platform – You like to also be involved in improving the devops aspects of our stack – Experience with any of AWS EC2 & ECS, Docker or JavaScript/NodeJS is a big plus – You have a proactive attitude and are not afraid of failing – You (want to) live in the Netherlands (remote is not possible) – You have a EU passport (we don’t provide visa’s)

You want to apply or you have any questions? Email Anne (anne[at]careibu.com).
