We're an early-stage (pre-seed) VC-backed startup automating RFPs in the AEC (Architecture, Engineering, Construction) industry.

We are building a online platform along with a direct Microsoft Word integration, helping firms find and win more work, while serving as their knowledge management hub for all business development.

Hard problems you will solve:

Deep Word Integration: Building a high-performance, "Cursor-like" experience within the constraints of Office.js.

Agentic Workflows: Orchestrating AI agents that can read complex government requirements, reason about compliance, and generate winning output autonomously.

Evolving Knowledge Graph: Architecting a library system that doesn't just store files, but learns from project history and feedback loops.

If you want a chance to work on a hard problem, in an exciting space, with a strong team that has validated the market and de-risked the business, with major upside, let's talk!

WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight.

We’re looking for senior software engineers to build our data platform and help us ingest and model messy, unstructured data into insights and actionable intelligence. At the heart of this is a 50m+ entity knowledge-graph with 200m+ relationships represented - and we need your help to build a system that can scale this up by an order of a magnitude. Today, we mostly use Python, Postgres, Airflow and Pyspark.

If you have prior startup experience, can bring strong Python (PySpark is a big plus) experience and have previously worked with TB-scale data sets - we’d love to talk to you.

MONUMENTAL | https://www.monumental.co/ | Amsterdam, The Netherlands | Full Time | Onsite

We make robots that autonomously construct buildings. We are currently developing and manufacturing our autonomous bricklaying system in the beautiful centre of Amsterdam. And our robots are already earning real revenue operating on construction sites all over the Netherlands.

We're looking for experienced software engineers for many roles. You can help us solve problems like:

- Data sync and analytics queries across a fleet of robots (that can be offline for hours at a time)

- Modelling buildings in code and finding the right UI for operators to edit them

- Designing systems for robots to drive safely and fully autonomously around a building site

Check out the progress we've already made on Atrium, our operating system for robotics: https://www.monumental.co/atrium

We're rapidly scaling up operations and we need experienced engineers who can build the systems that manage all of that complexity. If you think that 'full-stack' could reasonably mean debugging firmware, mixing buckets of mortar _and_ writing React components, we are looking for you. Robotics experience not required!

We detect buying signals across your tech stack, prioritize opportunities, and help B2B sales teams focus on deals that actually close. We're early, agentic-first, and moving fast.

Senior Software Engineer: You'll own complex technical problems end-to-end—translating customer needs into scalable architecture, optimizing AI model efficiency through prompt engineering, and shipping features that directly impact how revenue teams operate. We want bold ideas and people who push boundaries.

Junior Software Engineer: You'll work across our stack (Python, FastAPI, Next.js, React) alongside senior engineers, contributing to real features from day one. Great fit if you're hungry to learn, ship fast, and grow with a startup building cutting-edge agentic systems.

New Grad Software Engineer: Entry point for recent grads excited about AI and agentic systems. You'll get hands-on experience with our modern data stack (Postgres, ElasticSearch, ClickHouse, DuckDB), Kubernetes/AWS deployment, and Temporal.io workflow orchestration while shipping production code.
