OneChronos | Engineering Manager, Data Platform (NYC, Hybrid) · Software Engineer, Quality / SDET (Flexible/U.S. Remote) | Full-Time

We’re a Series B trading technology company reimagining how financial markets match buyers and sellers -- applying auction theory and innovative technologies to build fairer, more efficient trading infrastructure. Our production systems are written in Rust and execute billions of dollars in securities transactions daily. If you want to work on genuinely hard problems at the intersection of markets, mechanism design, and distributed systems, we’d love to talk.

We’re hiring engineering talent companywide, with a current emphasis on these two roles:

Engineering Manager, Data Platform -- Lead and grow our data engineering team while staying close to the code. You’ll own the roadmap for the pipelines, data services, orchestration, and platform infrastructure that power our analytics, and contribute to production systems alongside your team. 8+ years of software or data engineering experience, 2+ managing engineers. Strong Python, SQL, Rust, and TypeScript. Experience with workflow orchestration (Temporal, Airflow, Dagster or similar) and columnar formats (Parquet, Arrow). Financial markets or exchange experience a strong plus. NYC-based, hybrid.

ESTIMATED COMPENSATION: $180,000--$250,000 depending on experience, with eligibility for a discretionary annual bonus.

Software Engineer, Quality (SDET) -- Build the quality engineering function from the ground up. You’ll design and own automated test frameworks, CI/CD integrations, staging environments, and validation tooling that help engineers ship with confidence. Proficiency in a systems-level language (Rust, C++, Go, or Java) and Python required. Experience in low-latency or performance-sensitive environments a strong plus. Flexible/U.S. remote.

ESTIMATED COMPENSATION: $150,000--$200,000 depending on experience, with eligibility for a discretionary annual bonus.

Empower Pharmacy is hiring engineers to work on event-driven, distributed systems that actually run a real-world business (regulated pharma), not ad tech or yet another CRUD SaaS.

We just filled one Staff Engineer role directly from my last LinkedIn post (thanks to everyone who shared/applied). Now we’re expanding the team:

- 1 Staff Software Engineer - 4 Senior Software Engineers - 4 Software Engineers (new grad / early career)

All roles are US-based (remote within the US).

We’re a small team owning the core platforms that run manufacturing, operations, and logistics. A lot of the work is greenfield or foundational: distributed systems, workflow orchestration, reliability/observability, and making it all scale in a domain where correctness actually matters.

Tech stack: Java / Spring Boot, React / Next.js, Azure (Service Bus, Kubernetes), SQL Server. Event-driven, service-oriented architecture at enterprise scale. We use AI-assisted development heavily in the workflow (not as a bolt-on), so if you already lean on tools like Copilot/LLMs, you’ll be at home.

We’re setting up a round-robin “Virtual Interview Day” early next week so we can run both interview rounds in a single day for candidates who advance. The process is straightforward: practical discussions, system design, and code; no brainteasers.

If you: - like thinking in terms of systems and failure modes, - are comfortable across the stack (or want to grow there), - and want your work to have direct impact on how a real business operates,

then I’d like to talk.

* A well designed API first approach; one customer compared our APIs to petrichor

* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)

* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration
