Job Description

tl;dr: We're looking for an excellent engineer with solid Go experience to join our small, distributed development team. We're in Los Angeles, San Francisco & Paris; substantial time-zone overlap with CET (Paris) is key because our lead frontend engineer lives & works there.

Who we are

At Synthro, we are creating Foam, a new paradigm to collect, organize, create, and share your data, to help people think better together.

While we have developed core elements of the experience, we have many technical challenges ahead. Our team collaborates and leverages process, automated testing and group decision-making to get stuff done.

Our technology environment is Linux based, runs in AWS and utilizes Go, React, and JavaScript. We are leveraging an array of AWS services to deliver our solution and extensively take advantage of open-source solutions.

We're in the scrappy startup phase: we all work from home, even before the pandemic.

Role overview

We're hiring a Backend Developer to work with our team. You will focus on the backend for our web app. You will work closely with our frontend developer and be responsible for the API, data models, architecture, and AWS environment.

We love junior developers, but this role is for someone senior.

About you

Here's how to tell if you'd be a good fit for this job.

Must-haves

• You've built and shipped Go services (RESTful, HTTP), preferably something you can share with us
• You dream in idiomatic Go (2+ years experience highly desired)
• You don’t feel like you’re done until you have 85% unit test coverage
• You have solid knowledge of Postgres, specifically stored procedures & triggers
• You have solid working knowledge of core AWS services (ECS, EC2, RDS, S3, Cloudfront, Route 53)
• Your git history reflects you’re an excellent written (and verbal) communicator

Nice-to-haves

• You have worked from home or remotely for a distributed team
• You have experience with infrastructure-as-code (we use Terraform on AWS)
• You live in or within an hour of CET (Paris)

Why you might want to work with us

• We're small, so there are no layers of bureaucracy to work through. You can have a huge impact here.
• We have as few meetings as we can get away with.
• You can work remotely as long as you have substantial overlap with our primary time zones, Pacific and Central European. We call these “office” hours.
• Outside of “office” hours, you can work whenever you like.

Why you might not want to work with us

• We’re a startup, with all the good and bad that comes with that.
• We’re a small team. At the end of the day, you need to be able to solve your own problems.
• You own the infrastructure so you need to deal with it when it breaks.

Pay

We're looking for someone great, not someone cheap. If you're expensive but amazing, we can probably make it work.

You will help design, create and improve our central automated trading platform, written mostly in Go. You will help to make our architecture even more secure, resilient and fault-tolerant while maintaining a modular, well-tested architecture with simple and elegant code, focussed on speed and latency. A good line of code for you is the one which wasn’t written. You see infrastructure as code and see the deployment and monitoring as an integral part of your work, DevOps-style. You rather try to use a AWS cloud service instead of running your own piece of infrastructure or code. Security is always on your mind, and you’re maybe always a little bit too paranoid. You will also help research developers to port their Code to Golang and maintain code quality. You love to explore new state-of-the-art tools and discuss them with your team. Contributing to Open Source projects (e.g. modules to connect to exchanges) is an important part of your work as well. You’re super detail and quality oriented and love to work in a team where most problems haven’t been solved so far - so we highly value creativity to find solutions.

• Deep understanding of modern cloud-based backend architectures and technologies
• Golang coding experience
• Database technologies, especially latency-focussed NoSQL (AWS DynamoDB, Redis, ElasticSearch, AWS S3)
• Distributed Systems (gRPC, Redis)

• Maintaining a CD/CI Pipeline (AWS CodePipeline/Build/Deploy, Github Actions, TravisCI)
• Monitoring tools (AWS X-Ray, AWS CloudWatch, Datadog, Honeybadger, New Relic)
• Security Tools and Concepts (especially on AWS: VPC, IAM Roles, Security Groups)
• Excellent problem-solving skills and high attention to details
• Highly self-organized, self-learner, strongly quality oriented
• Fluent English speaker

Beneficial Requirements

• Analysis and math skills
• Experience with Python, JavaScript/TypeScript (AWS Lambda) and Ruby (on Rails)
• Experience with Serverless technologies (AWS Lambda)
• Experience with big data management and analysis toolchains like Databricks, Apache Spark, Kinesis
