DoStuff | Retention Product Engineer (Full-Stack) | Austin or Remote (US time zones) | Contract to hire preferred

I’m Scott - founder of DoStuff. We have a pretty big, and growing, membership product called DoMORE - $7/month for a pair of tickets to an event we think you’ll like. We’re hiring a hands-on Retention Product Engineer to own engagement → churn reduction end-to-end.

You will analyze cohorts, define the retention north-star metric, ship product and lifecycle experiments yourself, and measure impact.

This is not a PM-only role and not a pure engineering role. You own the full loop: insight → build → measure → iterate.

Our stack: React (FE), Ruby on Rails + Elixir (BE), Postgres, Elasticsearch. Proprietary lifecycle tooling for email, SMS, and in-app (web). No feature-flagging or experimentation framework yet - you’ll help install the remaining plumbing.

Retention is the highest-impact opportunity in the business and this role has real authority to ship.

If you have experience with the above and this sounds like fun, reach out to scott+domore@dostuffmedia.com with something in the subject line that let’s me know you’re real and interested. THX

Email: poetic.artifice@gmail.com

I am a seasoned (>15 years experience) full-stack staff-level software engineer specializing in the backend, systems architecture, AI, platform engineering, internal tools, prototyping, and data engineering. In addition to strong programming and architectural skills, I'm a force multiplier for any team in either role through the three T's -- teaching, talking, and tooling. I also hold a US patent in the AI space.

In the past, I've taught a number of scientists and students to code in python; I've led and managed a number of high-impact engineering teams of up to 12; and pioneered a number of no- and low-code solutions for stream processing, data model and query generation, form building, workflow systems, and front-end construction for a variety of industries, including those with strong regulatory requirements and complex business rules such as healthcare and fintech. >10% of all medicare applications and millions of individuals currently flow through pioneering no-code systems I conceived and built and have ran in production for over a decade.

More recently, I've built a no-code automated form-filler; a no-code web scraper (and an AI for generating such scrapers from a spec and 1-3 example urls from a page); and a workflow engine for coordinating LLMs and other generative AI processes, and on top of this a platform for both minimizing hallucinations and working with documents that are far too large for existing context window inputs or outputs using a novel, patented process that I invented; and applied these tools to various contracted projects requiring analysis and and cross-checking of information and other forms of integrity across textual and video/audio corpus data in a variety of domains (fiction and non-fiction).

I am also an improvisational pianist, published poet, and I've created novel algorithms and tools for studying and composing both music and poetry, which I have given a talk on at a recent functional programming conference.

I have extensive experience working for and running startups, software consulting shops, with some mid-sized company engineering experience as well; these give me a unique insight into speaking with customers and internal stake-holders, translating between engineering and other departments, gathering requirements, aligning stake-holders across departments on a vision and attainable timeline, and architecting/building/taking ownership over significant internal and customer-facing areas of responsibility.

If any of the above seems like a match for you and your organization or project, don't hesitate to reach out. I am available for both full-time positions and short- and long-term contracts.

Return | REMOTE | Software engineer backend (Go/Golang) | Full-time

Return (https://return.energy) is hiring a software engineer to work on platforms that accelerate the transition to carbon-free energy. Return’s main activity is building and operating industrial-scale Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will make a measurable, country-level impact on the transition to renewable energy. Return recently raised €300M to support its growth.

While we employ more than 120 people, Return’s technical team remains small with 13 members. Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service.

During the first three years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced software engineer.

Your primary focus will be to further develop our battery virtualization platform, enabling customers to use slices of battery capacity distributed across our fleet of industrial-scale batteries.

Our tech stack and toolset are straightforward: Go, Python, Ruby, PostgreSQL, TigerData, dbt, Dagster, Grafana, Terraform, and self-hosted plus cloud compute. We keep meetings to a minimum to provide at least five hours of uninterrupted coding time per day. We conduct code reviews and apply both automated and manual testing. Our web apps and platforms are often deployed multiple times per day.

Return has offices in Amsterdam, Berlin, Brussels, Hamburg, Munich, Madrid, and Stuttgart. We are very open to remote work as long as you live in the EU. Our hiring process is swift but thorough: a brief call to get acquainted and discuss finances, followed by one or more technical interviews, and a paid visit to Amsterdam to meet the team.

The tech team members have co-founded several companies and have worked with remote development teams since 2008, and they will personally guide you through most of the recruiting process (there is no recruiter involved).

We aim to hire you in February or March ultimately.
