Why Redian, and why this shape of team
You've landed here because you need Java developers for a team based in or serving Amsterdam, Netherlands, and you're weighing whether to hire locally, use a marketplace, or engage a delivery partner. This page explains how Redian Software delivers exactly that engagement — onsite, Java developers, aligned to Amsterdam business hours (CET / CEST), on a commercial model that scales from a single engineer to a full offshore cell.
Java / Spring Developers — what our engineers actually do
Redian's Java practice runs the JVM stack for enterprise-grade backends — Spring Boot microservices, JPA / Hibernate on relational databases, Kafka for event streams, JWT / OAuth for auth, containerised deploys, and the observability wiring (Prometheus, Grafana, OpenTelemetry, structured logs) that a bank or insurer's ops team requires. We also ship Kotlin on Spring for teams that want the ergonomics without leaving the JVM.
Seniority mix: mid-level engineers (3–5 yrs, own features and modules), senior engineers (5–8 yrs, own service boundaries, DB schema design, performance tuning, code review), and staff engineers / tech leads (8+ yrs, own system-of-services architecture, migration planning, on-call rotations). Typical engagement is 4–8 engineers with a fractional tech lead, sized to sprint velocity.
The Amsterdam context
Amsterdam's tech scene is a mix of financial services (ING, ABN AMRO, Rabobank, Adyen, Bunq), scale-ups (Booking.com, MessageBird, Uber's EMEA HQ) and a growing base of AI and climate-tech startups. Loaded senior IC costs are below SF but hire timelines are long, and DNB / AFM / GDPR posture is procurement baseline for anyone touching financial data.
Redian ships CET-aligned coverage from India during your Amsterdam morning — standups, code review, incident triage and design conversations inside the overlap. We deliver under GDPR expectations and are comfortable with Dutch procurement teams.
Onsite engagement — the mechanics
Onsite engagement — engineers work from your office. For clients whose delivery model needs on-the-ground presence — regulator-mandated controls, hardware access, in-room collaboration with an internal team, or leadership preference — Redian deploys engineers to your location on a per-diem or medium-term contract. We handle visa, work-permit, accommodation and travel logistics from our side; you provide the desk, badging, and access to the systems the engineer will touch.
How the commercials work. Onsite carries a different rate card than remote — day-rate is higher to cover the engineer's living cost and per-diem, and minimum engagement is usually 3 months to make the mobilisation worthwhile. We can also blend the models: a small onsite core (2–3 engineers) plus a larger remote build team, so you get the trust of physical presence without the cost of an all-onsite ramp.
Commercials and how to start
Rates depend on the exact seniority mix and length of engagement, but as a rule: a onsite Java developer from Redian lands well below the loaded cost of the equivalent local hire in Amsterdam, without dropping seniority. Minimum engagement is one month for remote, three months for onsite. Rate card, sample CVs of currently-available engineers, and reference clients in your industry — happy to send those on the first call, subject to NDA.
How the first two weeks look: we scope the roles, seniority mix and start date on a 30-minute discovery call. We share 3–5 CVs matched to the brief within 3 business days. You interview shortlist candidates directly. The chosen engineer(s) start inside 1–2 weeks (4–10 weeks if onsite mobilisation is needed), on your tools, in your workflow, with named Redian consultant oversight.
No lock-in, no minimum quarter. If an engineer isn't a fit inside the first two weeks, we swap them, no charge. If you need to scale up or down mid-engagement, we do it — that flexibility is the whole point of engaging a partner instead of hiring FTEs.
