Rumble brings together the best of IT, security and networking technology to deliver amazing network discovery and asset inventory capabilities for modern enterprises.
An accurate network inventory is a fundamental building block of all security programs, yet most inventory products do a poor job of network-based discovery because they only see it as a stepping stone to the “real” product features. Legacy products work by sending sensitive credentials to every asset on the network and fail to handle today’s hybrid environments. Without a solid inventory, most companies struggle with attack surface reduction, network management, and incident response.
Rumble Network Discovery is a product of Rumble, Inc. We are a fully virtual, high-growth startup based in the United States. Our founders each have over 20 years of experience growing companies in the information security industry, including Rapid7, Veracode, BreakingPoint Systems, and PGP.
Rumble has already proven its market fit. Rumble appeals to companies of all shapes and sizes; we have customers that range from museums to Fortune 500 technology companies. We serve the low-end of the market through eCommerce and the mid-market and enterprise segment through inside sales.
We’re building the engineering team to lead Rumble into the future. Our work is a mix of Go development, low-level protocol research, standard web technologies, PostgreSQL, and a mix of cloud technologies and integrations. Our platform is cloud-agnostic, can be self-hosted, and builds from a single repository. We ship daily and focus on incremental delivery with fast turnaround for customer requests and bug fixes. We bootstrapped to product market fit and recently raised a $5m venture capital round to accelerate our growth. The company was cash-flow positive in 2020.
We’re looking for senior engineers that are excited about research-driven product development and want to help build a company focused on happy customers and product-led growth.
We’re searching for senior engineers to grow our team! You will contribute to all stages of development, deployment, support, operations, and product planning. This position reports directly to the CEO today and will split into functional teams once the team expands. This is a growth opportunity for future engineering leadership as well as long-term individual contributors.
Contribute your skills and knowledge to building, supporting, and operating an amazing product experience for our customers.
Learn as you go to understand customer needs, product structure, fingerprinting techniques, and network protocols.
Self-task and coordinate with the rest of the engineering team to move the product forward, solve customer challenges, and keep the platform running smoothly.
Work with customers to identify bugs, understand gaps in product functionality, and flag opportunities for improvement.
Work closely and communicate effectively with functional teams across the company to keep our customer experience aligned with product and sales operations.
A strong track record of building products that customers love.
5+ years of experience in programming-heavy engineering roles with a demonstrated ability to ship quality results, frequently.
Go programming experience is preferred, but if you have deep experience in other languages and are excited about learning Go, we can make that work too.
Extensive experience with web development (HTML, CSS, plain JS) and a solid understanding of the HTTP protocol and the web browser security model.
PostgreSQL database experience, but other SQL database experience is also applicable.
A solid understanding of standard development tools and processes, including Git and issue-management systems.
Confidence working with Linux instances for deployment and diagnostics.
We’re a fully remote company but you need to be located in the US, with US citizenship or permanent residency for healthcare, payroll, and legal reasons.
We offer an extensive set of benefits including:
Competitive salaries and a stock option plan.
Top of the line medical, dental, vision, life and disability coverages with Rumble paying for 99% of the premium.
A flexible vacation policy.
401(k) match program.
To apply for this role, please send your resume and information about the products you have worked on to careers@rumble.run.
We encourage under-represented applicants to apply, even if you don’t think you fit 100% of the criteria (nobody ever does)!
About Herdius:
Herdius is a Berlin based Blockchain Company. We are working on building homomorphic distributed private key generation which then is turned into value bearing products in different sectors. Currently we are very close to open beta-testing for the Herdius-Crypto-Wallet. What we focus on on the blockchain field specifically is interoperability and trading. When connecting different chains on the key level, users can eliminate communication channels, bridges and complex systems. In other words, users can do cross-exchange and chain token swaps very conveniently and profitably for the user due to the cross-exchange arbitrage opportunities. The broader vision is one day to replace API auth keys with public-private key cryptography in order to provide layered access to user data.
All this makes for a crypto eco system and hedge fund that pays interest on all cryptocurrencies (that right now are unfortunately somewhat unusable and just laying around on wallets).
About the role:
Herdius is seeking for a Gopher Guru - an experienced Senior Golang Backend-Developer - to join our team of smart and visionary individuals. Experience in Blockchain is not necessary but a big plus.
We do not look at this role as another standard job but rather as great opportunity to build something really meaningful und amazing. Become a member of our great collective of top nodge engineers and people - altogether working to create cutting edge tech for the masses.
Besides the Herdius HQ in Berlin our Dev-Team is working mostly remote on different time-zones - so this vacancy surely also is location agnostic.
We would expect you to contribute at least 20hrs per week for part-time but joining full time is possible, too.
Cool things you will work on:
Skills & requirements
Your education or professional experience at the end of the day does not matter to us. It all comes down to us being convinced by your skills and drive! We mainly look for people who are passionate about projects they work on and have the drive to see a project through. Our code is mostly done in Golang with some Solidity for connectivity with Ethereum.
How to apply:
Send anything that reflects on your knowledge and experience in the field. Besides a CV/LinkedIn-profile you can send links of your GitHub/Stack Overflow/Portfolio/ or something awesome you've built that you’re simply proud of.
