Guidewire Integration
Integration Developers Who Know What Breaks Between the Systems
Hire Cloud API, messaging, plugin and batch specialists who connect Guidewire to the rest of your estate — rating, documents, payments, bureau, vendors and the data platform. This is the hardest Guidewire hire, because the work sits in the gaps nobody owns.
Across PolicyCenter, ClaimCenter and BillingCenter, on-premise or Guidewire Cloud. Contract, contract-to-hire and dedicated pods.

Why This Role Is Hard to Fill
Integration Is the Guidewire Hire Most Programmes Get Wrong
Configuration work is visible and self-contained. Integration work is neither. It spans Guidewire, middleware, third-party systems and whatever the network and security teams allow, and it fails in production rather than in test. The engineers who are good at it are good at other people’s systems too, which is rarer than Gosu fluency.
We screen on failure, not features. What happened when the downstream system went down mid-batch? How were retries, poison messages and duplicate events handled? Who owned the contract when the third party changed their payload? What did the move to Cloud API change about the design? An engineer who has genuinely done this work answers those quickly and with specifics.
All Guidewire Talent- Configuration CVs Sold as Integration“Worked on integrations” often means consuming one API someone else designed. We look for ownership of the interface end to end.
- No Failure-Mode ThinkingRetries, idempotency, poison messages, replay and backlog recovery are the whole job. Engineers who have only built happy paths surface late.
- Cloud API Learned From DocumentationCloud API and Integration Gateway change the design, not just the syntax. We check whether the shift was lived or read about.
- Guidewire Depth Without Estate DepthStrong on Gosu, lost the moment the conversation moves to queues, gateways, certificates or firewall rules.
- No Operational ExperienceSomeone has to clear the messaging backlog at 2am. Engineers who have been on that rota design differently.

Engagement
Compare all modelsFour Ways to Bring Integration People On
Contract Staffing
Named specialists for a defined period — one interface workstream, a migration wave, a backlog clean-up.
DetailsContract-to-Hire
Work together first, convert to permanent once the fit is proven on your estate.
DetailsDedicated Technology Teams
A standing pod that owns the interface inventory and keeps it healthy release to release.
DetailsProject Team Staffing
A scoped outcome — a cloud migration, a set of third-party interfaces, a conversion.
DetailsHow We Get to a Shortlist
Screening, in the Order It Happens
Four steps, and you hear from us at each one.
- 1
Requirement Intake
Which modules, which counterparty systems, Cloud API or on-premise mechanisms, and who owns the middleware.
- 2
Platform Screening
A Guidewire-experienced reviewer probes failure modes: retries, duplicates, backlog recovery, interfaces owned in production.
- 3
Shortlist With Notes
Profiles arrive with a written view on depth by area, notice period, rate and known gaps.
- 4
Interview and Onboard
We coordinate panels, handle paperwork and stay involved through the first weeks on your estate.
Profile Shapes
What an Integration Shortlist Tends to Contain
Representative profile structures for the three most common briefs.
Senior Integration Developer
Cross-module · on-premise and cloud
- Has owned interfaces end to end, including the production support of them
- Messaging, plugins and batch in live use across more than one module
- Comfortable in both Gosu and Java
- Can explain a retry and duplicate-handling design without prompting
Cloud API & Gateway Developer
Guidewire Cloud · migration and greenfield
- Built interfaces through Integration Gateway on a live GWCP programme
- Cloud API design and consumption, including app events
- Has remapped an on-premise integration to a cloud-safe pattern
- Works within cloud guardrails rather than around them
Integration Architect
Multi-system estate — carrier or delivery partner
- Owns the interface inventory and the patterns behind it
- Decides what sits in Guidewire versus middleware, and defends it
- Has negotiated contracts with third-party providers
- Sizes and sequences interface work across releases
These are representative profile structures, not live availability. Current availability, notice periods and rates are shared against a specific requirement.
Before You Send a Brief
Questions We Get Asked
Do you place integration people who are not Guidewire specialists?
For the middleware layer, yes — API platform and queue work does not always need Guidewire depth. For anything touching Cloud API, messaging, plugins or batch inside InsuranceSuite, we hold the line on Guidewire experience, because that is where the expensive mistakes happen.
Which modules do your integration developers cover?
All three core modules, and we screen for the specific one your interfaces touch. See PolicyCenter, ClaimCenter and BillingCenter talent for module-led briefs.
We are moving to Cloud API. Does that change who we should hire?
It does. Cloud API and Integration Gateway change the design boundaries, not just the syntax, so we look for engineers who have made that shift on a live programme rather than read about it. See Guidewire Cloud talent.
Can you staff production support as well as build?
Yes, and we recommend asking for it explicitly. Integration engineers who have carried the pager design more defensively, and a build-only brief often produces interfaces nobody can operate.
Can we start with one developer and scale later?
Yes — a single specialist is a common starting point. If the scope grows, the same engagement can extend into a dedicated team without re-contracting from scratch.
What do you need from us to start?
A JD if you have one. If not: which modules, which counterparty systems, Cloud API or on-premise, who owns the middleware, seniority, engagement type and location expectations.
