Headquarters: Fully remote company (worldwide, incorporated in France)
Do you care about contributing to open-source, and appreciate a good challenge? We do too! :) 
Open-source
We are a team of veteran open-source developers, working on educational and community-based projects in an open-first environment – and we are looking for new members. By joining us, you will work full-time on open-source, pushing your changes to free software projects upstream through pull requests, contributing features, documentation, or help on public forums. 
We care deeply about contributing our work upstream. You will see the results of your work reused and recognized across the educational community, increasing access to quality education for everyone, everywhere.
Remote-first
Unlike companies who reluctantly started to accept remote workers recently, we have embraced it from day 1. For the past 10 years, we have based and refined our way of working around remote-friendly workflows, from the ground up. No day-long video meetings, mandatory work hours, or risk of being forced back into an office one day -- as long as you have a good internet connection, it’s none of our business when or where you work from. :)
We are all working remotely, from all continents (except Antarctica, at least so far - applicants welcome!). We use remote-friendly and timezone-agnostic workflows based on asynchronous principles and good documentation practices.
Online education
We are one of the main contributors to the Open edX project, the main open-source MOOC platform created by MIT, Harvard and many other top universities. It powers sites like edX.org, the MIT Open Learning Library, and the national online learning platform for France. We provide development and hosting for institutions like Harvard Medical School, Harvard LabXchange, Cloudera, Autodesk, and several governments. We are not affiliated with edX.org, but we contribute and work with them on various projects. 
Technical stack
The Open edX project is a large Python/Django codebase, with good code standards and architecture. Tasks are varied, from developing core platform features, custom exercises and tools for specific courses (XBlocks), customizing and deploying instances, working full-stack, operating our service infrastructure, improving our hosting platform, etc. You won't get bored here.
Contracting terms
This is a full-time, permanent contract position. We aim for long-term relationships -- once in, almost all team members stay for many years. 
We care about paying fairly: 
  • Team members set their own compensation level, which is paid based on hours worked (no unpaid overtime!). 
  • When determining your rate, we will expect you to factor in benefits (vacation, healthcare, purchase budgets, etc.) - the idea is to let you pick the benefits that are useful to you, rather than offer one-size-fits-all packages that aren’t always very valuable.
  • We also proactively apply generous raises team-wide, based on the company results at the end of each year. See the details about how we approach compensation in our handbook.
We also firmly believe in work-life balance: as long as you deliver what you commit to, there is a lot of latitude in how much work you can choose to accept. We are open to time commitments anywhere in the 30h to 40h/week range, and highly discourage working more than that. It’s important to have time to ourselves, as well as having some slack, and there are diminishing returns in working more anyway. We are currently recruiting precisely to preserve that balance, and ensure we have plenty of capacity to handle our projects.
Culture and Work Style
We are a highly collaborative development team working in an agile environment. We have built a mostly flat organization, composed of 30 senior developers with a handful of support staff. You will be working with highly competent individuals who take responsibility for their work, and the same will be expected of you.
We belong to self-organized teams, so management doesn’t interfere with our day-to-day responsibilities and leadership is situational. You will lead some projects and join others. You will have a great deal of discretion in the work that you do and most of your work will be publicly viewable in the open-source community. Team members are continually learning from each other, and we place an emphasis on sustainable work practices and mental health. We help each other out when the unexpected happens and give kudos and recognition for work well done.
Camaraderie is strong, standards are high, and so is the retention rate. We invest in documentation, tests, and automation so that redundant work is minimized and team members can focus on more interesting problems. The work is completely remote – the entire sprint planning process is done asynchronously, and the sprint process itself is iteratively improved. We focus on minimizing meetings so when they do happen it’s for productive reasons. In order to make sure we still get some face time, we schedule optional social events to talk, play games, and engage in other activities. We also meet yearly in person at the Open edX Conference (in non-Covid times!), and use the opportunity to meet everyone, along with the rest of the community, and do a team retreat.
OpenCraft runs on the open first principle. Most of our conversations, code, and policies are publicly viewable.
Our handbook, like much of our work, is publicly viewable and you can find it at https://handbook.opencraft.com/
You can also visit our forums at https://forum.opencraft.com/
We welcome applicants of all genders and ethnicities.
Basic Requirements:
  • Experience with contributing to free software projects - small contributions are completely fine, but you must have at least one patch or pull request merged in a third-party project, or been a maintainer of an open source project with significant adoption. (Note that you can contribute now to satisfy this requirement - see for example the Open edX release issues, fixing one of these issues is a great way to match that requirement.)
  • Senior developer with 3+ years working with Python
  • Experience with Python web frameworks, specifically Django
  • 3+ years of HTML, Javascript, and CSS (experience with React and/or Typescript is a big plus!)
  • Experience with unit testing
  • Comfortable working in a Linux environment, specifically Debian or Ubuntu
  • Experience with databases: MySQL, MongoDB, PostgreSQL
Additional Skills:
You will work on tasks from the following categories, but you can pick up the skills on the job if you haven't mastered these yet:
  • DevOps experience, especially on Debian/Ubuntu servers, Terraform, Vault, Packer, Prometheus, ELK, Docker. We are building a modern infrastructure and having a strong DevOps presence on top of core software engineering skills is a big plus with us.
  • Managing clients & projects from beginning to completion (senior developer)
  • Cloud computing, like AWS or Kubernetes
  • Configuration management tools such as Ansible, Consul
  • RabbitMQ, Redis & Elasticsearch
  • Mobile development (iOS and/or Android)
  • Public speaking at conferences (you would present a talk every year at the Open edX Con)
Apply for this Position
Our recruitment process differs from most other companies - we don’t believe resumes and traditional interviews to be particularly effective. Often, they tell more about how good someone is at interviewing, rather than at the actual work. So, our initial interview is lighter and easier to pass than in other companies - but we then provide you with real (and paid!) work to see how it works out in reality.
  • Step 1: You apply by filling out this form: https://opencraft.com/jobs/open-source-developer/ 
  • Step 2: We do two interviews with candidates matching the requirements listed above. The first interview includes a (simple) coding exercise.
  • Step 3: If this works out, we hire you! We start with a 2 months trial period, which allows both you and the rest of the team to fully evaluate how we work together, and is followed by a final review and confirmation.

Reactive Network Remote
Reactive Network is a fully EVM-compatible execution layer that allows developers to create the next wave of dApps using Reactive Smart Contracts. These contracts differ from traditional ones by using Inversion-of-Control for the transaction lifecycle, driven by data flows across blockchain ecosystems rather than user input.

Forward Labs (https://forwardlabs.ai/) is building superhumans, autonomous AI agents for global freight — the backbone of the global economy — a trillion-dollar industry. (think scale.ai for freight)
The company was founded in San Francisco by 3 friends from Xendit (YC S15, 1st YC unicorn in Asia from Berkeley) — early employees of an exited AI startup & 3 Y Combinator-backed startups from 0 to $1b+.
We’re now a fully remote team 🇺🇲🇨🇦🇰🇷🇵🇭🇸🇬. Our team is still quite small (<10) — so you’ll have a massive impact on the trajectory of the business from Day One + working with the founders directly and learning about Silicon Valley & emerging market experience.
Backed by Maple VC, Village Global (with LPs such as Jeff Bezos, Bill Gates, etc.), and other Silicon Valley investors and logistics leaders.

What we’re building

Our platform, Forward AI, allows forwarders to automate their processes from booking to tracking and billing - so they can grow their businesses to move goods seamlessly without hiring more staff
Forwarders lose business when they book late. It takes 10-40 emails to book a cargo. Human Agents take 1-5 days on each booking — our AI Agent cuts it to minutes. It cuts costs too, by procuring from 10+ carriers instead of 3. This adds up to 1000s of cargo each day.
Specifically, provision it with a corporate email, and our AI Agent takes care of inquiry, approval, quotation, procurement, and billing. It runs on GPT to talk to shippers, employees & carriers. And, we built a backend OS to pull pricing data & log new bookings like a TMS.

About the role

Responsibilities
  • Work closely with various stakeholders (primarily clients & customer success team) to gather requirements and translate them into technical specifications
  • Develop across technology stacks, including frontend, backend, databases, DevOps, automated testing, and alerting systems
  • Work across the entire product lifecycle from conceptualization to production
  • Architect and develop end-to-end operational solutions leveraging AI platform - focusing on accuracy, speed, and scalability
  • Design and develop robust integrations with various external freight (TMS) & communication (email) systems - utilizing APIs or RPAs
  • Write high-quality, maintainable, and testable code
  • Proactively seek and implement improvements to the team’s processes, codebases, and best practices
Example projects
  • Interoperable operational dashboard: to build a production-ready command center with the correct abstraction - supporting a variety of tasks with minimal customizations.
  • Multi-tenant workforce tool: to develop operational tools & integrations with reliability and scalability incorporated
  • Realtime document ingestion: to establish data ingestion infrastructure for both structured and unstructured data
  • Reverse engineering third-party software: to figure out the right architecture to integrate with external software without APIs - RPAs
  • Email onboarding/integration: to design 2-way integrations with multiple email providers, which even non-technical users can initiate
  • Automated QA: QA automation for UIs, internal APIs, and external integrations
Tech stack
We are tech-stack agnostic in terms of the skill sets we are looking for, but the tech stack looks like the below (expect this to change as we grow):
  • LLMs: OpenAI, Hugging Face, Mistral, DocumentAI
  • Backend: Python, FastAPI, Typescript, Supabase
  • Frontend: Next.js, GraphQL, Refine
  • Infrastructure: AWS, GCP, Docker
A great fit, some or all of the following
  • Strong understanding of system designs (idempotency, circuit breaker, message queues, etc)
  • Familiarity with unit, integration, and E2E test frameworks
  • Familiarity with instrumenting monitoring systems for ensuring the quality of the products in production (Sentry, Pagerduty)
  • Is scrappy, comfortable with ambiguity, taking end-to-end ownership to ship, and values progress over perfection
  • Wants to set, maintain, and adhere to great software engineering standards (architecture review, comments, testing, documentation)
  • Never bored of spending time on your favorite newsfeed (e.g. Twitter, GitHub) browsing the latest computer concepts, codebase, and system designs
