We are looking for candidates that are excited to join us on a mission to raise the standard of trust online. All of our roles are fully-remote, except where specific locations are noted.

Most of the software engineering positions have been repeating here for years because we've been continually hiring for them, scaling our whole team to now over 300 people—many of those hires have come through Hacker News. We've been improving our hiring process over time, and we know some good candidates may have fallen through the cracks. Some people who tried in the past have had success going through it again, and we still pay for hiring projects.

Viam | Staff Software Engineer & Senior Software Engineer, Infrastructure | Onsite 3 days (New York City/NYC) | https://www.viam.com/

Viam (founded by former co-founder/long-time CTO of MongodDB) is an open source robotics + AI developer platform. It is a single platform that brings software engineering maturity to robotics and automation.

Why this could be interesting to you: Impact: ~100 people (~70 engineers) with only a handful at Staff level → huge room for influence. Proven, technical founder: → scaling with traction and real customers. Tech: Backend-focused teams (Core Services, Infrastructure, Motion Planning) using Golang, MongoDB, Linux, GCP. Timing: Early enough to shape core architecture, late enough to see meaningful usage and scale.

Duranta | Full-Time | Staff backend engineers | Location: Seattle, WA or NYC | On-site

Company: we're a small startup (pre Series A) building a business-in-a-box solution for landscaping companies, initially targeting the US. It's a huge market with more than 700000 companies in the US alone but with very little good software. We're looking for a very experienced backend engineer (senior/staff level) capable of taking ownership and leading the development of entire systems.

We keep our infrastructure as simple as possible, so the entire backend is in Golang with Postgres+S3 as the data storage layer. And a bit of Terraform for the infrastructure.

We're NOT a standard "AI startup" doing LLM wrappers, but we do have our own computer vision AI that we use to produce models from satellite imagery. So if you're interested in working on unusual AI pipelines, we have plenty of work there too.

Our frontend is a React.Native app, and we're working towards having full feature-parity inside a regular webapp.

Experience:

* Go backend experience

* A lot of experience with distributed systems

* Designing robust APIs (we're using ConnectRPC)

* Ideally experience with offline apps and database synchronization

* The usual: infrastructure-as-code, Docker, Github actions, OpenTelemetry, etc.

Salary: $170-$210k and equity

Apply: https://jobs.lever.co/getduranta/50af551a-9a5c-498c-9729-6f2...

Moment | Distributed Systems Engineer, Product Engineer | ONSITE NYC | Full-time | https://moment.com | $200k–$325k + equity

Moment is building core infrastructure for fixed-income, the world's largest asset class (4M+ instruments, $150T total market). We work with some of the largest financial institutions to bring all of their fixed-income operations into a single platform.

Cool things we've built include a liquidity-aware portfolio optimizer, high-cardinality market data pipelines, and a best-in-class trading system and ledger. Backend stack is generally Go/Kafka/Postgres on ECS, though some of the quant-ier services are built in Python. Frontend stack is NextJS. Company stack is Slack/Linear/Notion.

Roles:

- Distributed systems engineer: build features + scale systems to model, optimize, and support an idiosyncratic, complicated domain

- Product engineer: build beautiful, powerful interfaces that put these new capabilities in the hands of asset managers, financial advisors, traders, and more.

Spacelift | Remote (Europe) | Full-time | Senior Software Engineer | $80k-$110k+ (can go higher)

We're a VC-funded startup (recently raised $51M Series C) building an infrastructure orchestrator and collaborative management platform for Infrastructure-as-Code – from OpenTofu, Terraform, Terragrunt, CloudFormation, Pulumi, Kubernetes, to Ansible.

On the backend we're using 100% Go with AWS primitives. We're looking for backend developers who like doing DevOps'y stuff sometimes (because in a way it's the spirit of our company), or have experience with the cloud native ecosystem. Ideally you'd have experience working with an IaC tool, i.e. Terraform, Pulumi, Ansible, CloudFormation, Kubernetes, or SaltStack.

Overall we have a deeply technical product, trying to build something customers love to use, and have a lot of happy and satisfied customers. We promise interesting work, the ability to open source parts of the project which don't give us a business advantage, as well as healthy working hours.

If that sounds like fun to you, please apply at https://careers.spacelift.io/jobs/3006934-software-engineer-...

You can find out more about the product we're building at https://spacelift.io and also see our engineering blog for a few technical blog posts of ours: https://spacelift.io/blog/engineering

Additionally, we're hiring for a new product we're building, Flows. Mostly the same requirements and tech stack, without the devops bits. You can see a demo of Flows and apply for it here: https://careers.spacelift.io/jobs/6438380-product-software-e...
