Open hourly rate 6-month initial contract (potential to extend or convert to hire) Remote, Eastern or Central time zone preferred
A space & defense company needs a Core Network Engineer to backfill a teammate going on leave, starting immediately. The focus is 4G/5G core and 3GPP standards, with the core delivered by a vendor and integrated into the company’s own network.
The vendor owns the core; you’ll own testing, troubleshooting and requirement conversations with them. This is a high-level networking role — deep certifications aren’t required, just solid hands-on core experience.
What you’ll be doing
Step into an active core network effort, backfilling a teammate on leave.
Test and troubleshoot core network elements and services from design through deployment.
Define feature requirements directly with the core network vendor.
Support integration between the vendor-delivered core and the company’s own RAN (gNodeB/eNodeB).
What you’ll need
Hands-on experience with 4G/5G core networks and 3GPP standards.
Comfortable testing, troubleshooting and defining feature requirements with vendors.
Working knowledge of RAN integration (gNodeB/eNodeB) — not the primary focus.
High-level networking expertise; no deep certifications required.
Able to start immediately and work Eastern or Central time zone hours.
US-based and eligible to work on ITAR-controlled programs
Nice to have
Background at a major telecom operator or vendor (Nokia, Ericsson, Mavenir).
Prior contract or independent consulting work — you land and add value fast.

Contract Business Development Consultant — Golden Dome
United States (Remote)
Open hourly rate
6-month contract – 20 hours per week +
Fully remote (US-based)
A space & defense company is hiring a Business Development Consultant to open the Golden Dome market through a 6-month engagement.
The infrastructure is built, the program is moving. What’s needed is a BD lead who has sold into missile defense or hypersonic test programs before, can build a pipeline without a long runway, and can carry it from first meeting to award on a fixed clock.
What you’ll be doing
Own the Golden Dome market as the sole business development consultant on the account.
Map the stakeholders, program offices, primes and budget lines behind Golden Dome hypersonic testing and test-vehicle launch, and turn that into a named target list within the first month.
Secure first meetings with program managers, contracting officers and prime-contractor capture leads, and qualify each opportunity against what the company can deliver on its current timeline.
Shape capture plans for test campaigns at the company’s site: vacuum, high-G, materials and wind-tunnel testing, and test-vehicle launch.
Draft responses to RFIs, BAAs and OTA proposals alongside the CEO and the engineering team, with the technical claims kept accurate.
Run a weekly pipeline review with the CEO: what moved, what stalled, what needs an engineering answer, what needs a decision.
Convert an initial test campaign into a multi-year test-services program of record.
What you’ll need
Business development or capture experience selling into the DoD, with awards you can name.
A live network across hypersonic test and missile-defense stakeholders: OSD, MDA, the Space Force, test ranges and the primes.
A working knowledge of DoD contracting mechanisms: BAAs, OTAs, SBIR/STTR, IDIQs, sole-source and cost-plus versus firm-fixed-price.
Experience selling test services, flight-test capacity or novel test infrastructure rather than standard components.
A record of opening a market from a standing start — first meeting to first award — rather than managing an inherited book.
Comfort representing engineering claims accurately to a technical customer without overstating them.
Judgement to qualify out early: this is a 20-hour-per-week engagement and the pipeline has to be real.
