Dover | San Francisco, CA | Senior Software Engineer | Full-time | ONSITE | https://www.dover.io/careers

Dover is building the first truly modern recruiting agency. We help some of the fastest growing companies hire the best talent for their open roles.

The Dover engineering team is small but incredibly effective. We value productivity over face-time, action over inaction, and focus over feature creep.

As one of our first few engineers, you'll have a massive level of ownership over our engineering culture, end-to-end ownership over the systems that you build, and influence on product direction.

At the core of what we're building is a simple question—"is person X a good fit for job Y"—but doing this well is challenging, requiring a combination of large-scale data scraping, aggregation and processing. We pride ourselves in automating things nobody thought possible.

We primarily code in Python, with some occasional JavaScript. We leverage Kubernetes heavily for our orchestration and deployment. We also make extensive use of Google Cloud, Docker, Postgres, Mongo, and ElasticSearch within our infrastructure.

You're a full-stack or backend engineer with 3+ years of software experience at one or more companies with a strong engineering culture. You're ready to be an individual contributor, design and build sophisticated systems quickly, and work in a fast-paced environment.

[still-unnamed startup in stealth mode] | REMOTE or ONSITE(around HK: Guangzhou,Macau,Shenzhen,Taiwan,etc) | 20-40h per week, freelancers/full-timers/part-timers

Sorry for the vague description but I can tell you more about the product we're building when you apply. Hopefully I can attract you in a sufficient way with our tech stack! (see below). [NOTE: this is not a pie-in-the-sky venture, you would be joining a team who has a 1.5+year-old working product, with prospects of new greenfield products built around the first.]

Job positions:

- Build engineer: you are a Linux-er who has some past experience building deb or rpm packages, are excited about reproducible builds, and are willing to learn (if you don't already know) new things such as snap or flatpak. gitlabCI and/or githubActions is a plus. (Might do some DevOps work after we come out of stealth mode as well; with Pulumi and RedShift.)

- C#/.NET developer: generics, LINQ, VisualStudio, EntityFramework et al are your bread and butter. You value the diversity that comes from learning other languages and tech-stacks but also the stability that a robust platform like .NET provides, which you based your career on. Desirable to be familiar with Xamarin, but not required. F# is a plus.

- Rust developer: you dealt with C/C++/Objective-C in the past but are ready to move on. However, you're still not convinced about garbage collected languages, so you have been looking at Rust lately, or willing to learn it. You're not a smart-ass though, so you would be excited to expose your Rust code's API to be consumed by higher level languages.

- FP developer: you value immutability and lack of side effects because you have lived the nightmares of race conditions and heisenbugs in your career. You're disgusted with most job positions out there because the tech-stack described in most of them don't look safe enough to be serious (sure they can build snapchats with them, but not robust software that would end up being used by NASA or Waymo). Desirable to be familiar with F#.

- Desktop/mobile developer: you cringe at the idea of "Electron apps", because you think native frameworks like QT or gtk+ give much power and maintainability (plus, performance aside, javascript is a joke in any other aspect too). But you also understand why garbage-collected languages are safer and more productive than low-level ones, and there are many of these much more decent than JS. (gtk is preferred for this position at the moment; or someone willing to switch)

- SmartContracts/blockchain developer: you've used/developed smart contracts in languages such as Ivy, MiniScript, or Solidity(EVM), or are willing to learn this technology. Desirable to have familiarity with atomic swaps, HTLCs or zero knowledge proofs. Excited about things like bitcoin-lightning, ethereum, mimblewimble/grin, DAI, etc

- Browser-extension developer: you would be interested in diving into the world of WebAssembly to create a similar opensource plugin like the UI of MetaMask (ideally this work should be compatible with Brave, Chrome/Chromium, and Firefox).

Important perk for all positions: all the code/scripts you'll write (being paid of course) will be opensource, at least for the first 2months.

Write me at andrew.forsure@gmail.com

PS: Abstain from applying if you expect a lead/managerial role, because the team is not yet big enough to need extra leadership for now.

PS II: In case you're only interested in joining part-time, note: I wouldn't find it acceptable if you join us to work remotely part-time while keeping your full-time job. Part-time only works in parallel with: a) your own side-projects, or b) other additional part-time job (because resting is important).

* Designing cloud infrastructure to serve billions of predictions for machine learning models via Kubernetes on Google Cloud Platform and Amazon Web Services

* Building scalable machine learning infrastructure so that ML engineers can train thousands of models at scale, visualize performance, and analyze results

* Working with Javascript-based data visualization and exploration libraries

* Designing and developing internal tools using the latest web technologies to enable computational chemists to explore molecular properties.

* Connecting Docker-based microservices and serverless scripts to enable automated dataset ingestion pipelines that speed up the pace of model development and serving.

* Writing continuous integration and delivery tools to build new Docker containers, deploy updated models, and distribute code in response to Git hooks or other web events.

* Owning the full development cycle of a product from ideation to implementation to deployment (of course in collaboration with a team!)

We were in the W18 batch of YC and are now based in the biotech hub in Cambridge, MA. We offer competitive salary and above-market equity. Benefits include full medical, dental, and vision coverage, flexible vacation policy, and gym membership.

Smarkets develops a reliable, low-latency, highly concurrent betting exchange based on trading exchange designs. We're also building a fast, modern web interface to allow for a smoother experience. Servicing our users is top priority.

The Smarkets platform is written predominantly in Python, C++ (replacing still present Erlang[ß]) and Javascript for React & React-Native, relying heavily on asynchronous programming techniques. The tech stack sports Kafka, Postgres and Kubernetes. We use REST where we can. Life at Smarkets circles around people, version control, configuration management and automation. We can - and do - deploy to production several times a day.

Our entire production is in AWS. In fact, Smarkets was the first gambling operator under the Maltese regulator to get permission to run everything in the cloud. We push the envelope where needed and educate auditors when necessary.

We are looking for engineering talent all across the board: frontend and mobile, infrastructure, trading engine, security - and of course generalists, those yet to find their calling.

If you like the idea of flat structure and practical engineering approach, see our jobs at https://smarkets.com/careers .

---

ß: to pre-empt questions on why C++ or why not Erlang - our exchange team have promised to put together a proper write-up on the tradeoffs, design constraints, performance needs, etc. In fullness of time, that is, when the most painful (and probably interesting) migrations are behind them.

newline (formerly Fullstack.io) | Book author | Remote | Part Time | https://www.newline.co/write-a-book Earn on order of $50k/year by writing a programming book. We’re the authors of Fullstack React, ng-book, Fullstack Vue and we’re looking to work with authors like you to write a few new books this year. Our books sell very well because: - We go way beyond API docs and teach everything you need to know to build real apps. - We guarantee the books and code are up to date. - We invest in marketing the books (and have an active email list of over 100k)

- We love the topics we write about and aim to create something remarkable every time.

If you decided to self-publish, you may find the marketing is more than writing the book. We have an audience, and we know what they want to read - so when your book is done, we already have people who want to buy it.

If you decide to go with a “traditional” publisher, you may be given a mediocre editor, write your book in MS Word (ha), and earn 5-15% in royalties. With us, our editors (me) are programmers first, our tooling is dev-friendly, and our royalties are split 50/50. (For scale, the author of Fullstack Vue earned $20k on the opening weekend, Fullstack D3 even more.)

We’re looking to write content about JavaScript, Building Full-stack web apps, ASP.NET Core, Serverless, Python, Kubernetes, Elixir, Blazor etc. Anything up and coming.

If this sounds like something you’d be interested in, fill out the form linked below. Looking forward to hearing from you!
