Estuary | US-Based / Remote | Full-time – https://estuary.dev/

Estuary is a VC-backed, post–Series A startup powering real-time data replication and transform — from sub-second CDC replication to terabyte-scale OLAP data flows. We’re open-source, developer-first, and focused on making data movement radically simpler across both our Platform and Applications layers.

We’re hiring for:

Head of Engineering — Own the engineering function end-to-end as a partner to our founder CTO: strategy, people, delivery, and operations across a compact but high-leverage team. You’ll grow the leaders already running our teams, set technical strategy jointly with the CTO, and be accountable for what engineering ships and what it costs.

Senior Systems Engineer (Control & Data Plane) — Build the high-performance backbone of our platform: the orchestration, distributed state, and stream transport that keep pipelines at sub-second latency under massive throughput. You’ll work primarily in Rust on fault tolerance, consensus, and networking, and help set the bar for correctness and performance across the team.

Product Manager — Own product areas end-to-end, working closely with engineering and design to shape the roadmap and deliver a great developer experience. Engage with users, translate real-world use cases into product decisions, and help define how modern data infrastructure should feel to build with.

Head of Product Marketing — Lead product marketing as we bring real-time, agent-ready data pipelines to technical buyers, partnering closely with our Head of Marketing, Developer Relations, and the founders. Own positioning, messaging, launches, and competitive narrative, turning what our engineers ship into stories data teams actually care about.

Solutions Engineer — Partner with sales and customers from the first technical call through production, running discovery, demos, and proofs of concept for data engineering and platform teams. You’ll design CDC, streaming, and batch pipelines on Estuary, solve real integration problems hands-on, and feed what you learn back to Product and Engineering.

Customer Success Manager — Own the post-sale relationship for our data engineering and platform customers as our first CS hire. You’ll build onboarding, account health monitoring, and the expansion playbook from scratch while staying technical enough to resolve most issues yourself.

Senior Compliance Engineer — Own our GDPR and PCI DSS programs while keeping our audited SOC 2 and HIPAA programs running smoothly, alongside hands-on ownership of identity, endpoint, and SaaS estate management. This is a governance-first role for someone who has run a compliance program end-to-end, not just contributed to one.

What we’re looking for: People who care about building reliable, maintainable systems and processes and enjoy working with complex APIs, data flows, or customer relationships. We value curiosity, clear communication, and a willingness to learn.

Bonus points for experience with CDC tools, open source contributions, or fast-paced startups.

Exponent | Lead Engineer, AI Accounting | New York (Flatiron) | HYBRID, 2+ days in office | $160k–$200k + equity | Full-time

Exponent is a financial platform for franchise and multi-location restaurant operators: charge cards, loans, and an AI-powered Accountant that pulls in an operator's POS, bank, payroll and processor data, reconciles it, and automates the monthly close.

You'd own core systems in the Accountant: idempotent ingestion from unreliable third-party APIs, the background jobs that keep thousands of accounts in sync, and the decisions about how LLM classification behaves inside a ledger that has to be right. Full stack, focused on backend architecture. Rails, Postgres, Sidekiq. We ship multiple times a day.

We want someone who ships fast and knows when to slow down. 5+ years, deep experience in any server-side framework (Rails, Django, Phoenix, TypeScript), and fluent with AI-assisted development. Fintech and Rails experience are strong pluses.

TheraPlug | Founding CTO / Technical Lead | Detroit preferred; remote considered | Equity-first, pre-funding

I’m Marcelus Brice, founder of TheraPlug (https://theraplug.health). We’re building a behavioral health platform focused on making it easier for patients to find appropriate therapists and access care through insurance, starting in Detroit.

We’re looking for a hands-on technical leader who can build alongside a lean team and help recruit its founding engineers. You don’t need a previous CTO title, but you should have shipped and operated production software.

The product will support iOS, Android and responsive web, including:

• Patient and provider onboarding, scheduling and secure messaging. • AI-assisted therapist matching based on clinical needs, preferences, insurance and availability. • Provider credential verification and payer enrollment workflows. • Insurance eligibility checks and estimated patient costs. • Secure video sessions and clinician-reviewed AI documentation.

Relevant experience includes full-stack development, mobile apps, healthcare integrations, sensitive-data security and practical AI implementation. We value clear architecture, accessible design and thoughtful use of established services.

Compensation: We are pre-funding and cannot offer an immediate cash salary. We’re seeking someone interested in an equity-first founding role, with a planned transition to salary when funding supports payroll. Equity, responsibilities, time commitment and compensation triggers would be agreed in writing before work begins. Funding timing is not guaranteed.

To start a conversation, email marcelus@theraplug.health with: • Products you’ve built and your specific contribution. • Relevant healthcare, security or AI experience. • Your location and realistic availability before funding. • Your interest in leading and assembling a small development team.

I can share the detailed product scope and team requirements.

IMC Trading | Machine Learning Engineer | Amsterdam OR London | ONSITE | Full-time

IMC is a research-driven trading firm and has been a market maker since 1989. Our researchers, traders and engineers work as one team on systems we build ourselves, trading across global markets.

We want ML engineers to shorten the path from a research idea to a live trading strategy. You’ll work with quant researchers, HPC specialists and software engineers in one of two overlapping areas:
