What you'd actually do: Run technical discovery, proofs of concept, benchmarks, demos and security reviews for banks and trading firms evaluating a time-series database.
Most people just hit Apply. Do these first and you show up with someone on the inside.
A friendly message to a current rep is the best way to stand out. Ask about their experience, not for a referral.
QuestDB is the low-latency time-series database on open formats. It ingests millions of events per second, computes on live data in milliseconds, and keeps years of history queryable: one SQL engine spanning messaging, stream processing and tiered storage, so teams can act on what is happening and learn from everything that happened.
The engine is written in low-latency Java (zero-GC), Rust, C++ and assembly: columnar storage, vectorized and JIT-compiled SQL, streaming materialized views, and an open lakehouse tier on Parquet and Iceberg. QuestDB Enterprise turns a single server into a fully distributed deployment with a multi-tiered lakehouse architecture, ready for mission-critical workloads on the critical path.
Our open-source repository has passed 17k GitHub stars and we're the fastest-growing database in our category. QuestDB runs in production at tier-1 banks, exchanges, trading firms, hedge funds, crypto platforms and energy operators across four continents, and is expanding into robotics, aerospace and Physical AI. We recently won Best Trading Analytics Platform at the TradingTech Summit Europe, the first non-legacy vendor to do so.
We hire talented and passionate people who share our mission to empower developers to solve their problems with data. We are building breakthrough technology to power the infrastructure of tomorrow.
We're hiring a pre-sales engineer for North America to own the technical side of every sales cycle in the region.
You own the technical validation that happens before a deal is signed: discovery, a time-boxed proof of concept with success criteria agreed up front, benchmarks run on the customer's own data that their engineers can reproduce, architecture sign-off and security review, through to the first production workload. You are the engineer in the room when a bank's platform team asks how replication and failover actually work, or when an aerospace team needs rocket telemetry streamed and queried in real time. Most evaluations are for new projects at firms that already run incumbent systems, so much of the work is making the case credible against what they know: the architecture, the numbers, and a plan their engineers believe they can execute.
You report to our Head of Sales and work with the sales team on every deal, with direct access to our CEO. You also work directly with our CTO and core engineers on the product, so what you learn in the field goes straight into the roadmap. This is a hands-on individual-contributor role with a lot of customer time and a lot of autonomy.
In your application, include a short note on why this role, and one evaluation or migration you ran that you are proud of, including what you would do differently now.
