Sweetch Energy

Company Overview

Name

Sweetch Energy

Headquarters

Rennes, France

Founded

2015

Size

Approximately 40 employees (source: preqin.com). The company has secured nearly 40 million euros in total funding by December 2023 (source: eu-startups.com).

What They Do

Sweetch Energy is a French deep-tech startup focused on osmotic energy generation, a non-intermittent renewable source derived from salinity gradients in estuaries and river deltas. Their patented INOD® technology utilizes high-efficiency eco-membranes in pressure-retarded osmosis systems to generate clean electricity 24/7, marking a viable commercial breakthrough after 50 years of research (source: eu-startups.com). Their products include modular power plants deployable at river mouths, with the first demonstrator under construction on the Rhône delta in partnership with CNR (source: eu-startups.com). Target markets extend to Europe and North America, focusing on utilities and industrial partners needing baseload renewables to complement intermittent sources like solar and wind (source: eu-startups.com).

Projects & Achievements

Although Sweetch Energy has not yet completed any fully commercial projects, its flagship project is the INOD® demonstrator on the Rhône delta, under development since at least 2023 with CNR. This site utilizes the salinity gradient of the estuary to test the technology, with 25 million euros allocated in December 2023 to complete it (source: eu-startups.com). Ongoing efforts include global expansion plans for Europe and North America, supported by a funding round of $15.5 million in October 2024 (source: cbinsights.com). Key clients and partners include CNR and EDF Group, providing strategic links for the development of osmotic technology (source: eu-startups.com).

Recent Developments

Over the past two years, Sweetch Energy closed a funding round of 25 million euros (~$27.3 million) in December 2023, led by Crédit Mutuel Impact, enabling the completion of the Rhône demonstrator and expansion of R&D (source: eu-startups.com). Another funding round of $15.5 million occurred in October 2024, bringing total funding to over $59 million across six rounds (source: cbinsights.com). Investments from EDF Pulse Ventures have strengthened ties since their investment in 2022, highlighting ongoing commitment to the development of osmotic energy (source: eu-startups.com).

Working with Them

Sweetch Energy offers roles within a team of ~40 people, including positions in engineering, business development, and leadership. The headquarters is located in Rennes, France, with potential remote work opportunities as part of the expansion into North America and Europe (source: f6s.com). The company culture reflects a high-growth startup environment, with a persistence of 10 years in R&D and an ambition supported by investors to become a global leader in osmotic energy (source: frenchtechjournal.com). Details on benefits are not publicly available, but the scale of funding suggests competitive packages for engineers and strategists in the renewable energy sector.

We are looking for a Development Engineer to provide comprehensive engineering support for our distributed energy and microgrid projects. Our projects typically include managing a variety of DER and microgrid assets - such as solar, energy storage, controls, and reciprocating engines.

This role will report to our Manager of Development Engineering and will be a hybrid role based out of Ridgewood, NJ, or NYC office.

Key responsibilities will include

  • Create electrical and physical designs for microgrid and DER systems, accounting for existing electrical infrastructure, AHJ requirements, and other site constraints
  • Utilize your strong technical and communication skills to identify and communicate technical constraints and possibilities to other internal and customer stakeholders
  • Work extensively with our Business Development (BD) teams to evaluate and develop the right technical solutions
  • Work with the BD, execution, and commercial teams on specific projects to ensure the Microgrid integration is technically sound, practical, and cost-effective. This includes working with existing service entrance one-line drawings or creating new ones to provide the best design interface for functionality and cost
  • Investigate the interconnection, which includes submitting interconnection applications and completing modifications to existing design concepts that are applicable to each site
  • Work with switchgear manufacturers (and other OEMs) like Schneider Electric to ensure switchgear designs meet project requirements, including site constraints and utility requirements, within cost and schedule constraints. This includes working at voltage levels of 34.5kV, 23kV, 13.8kV, 4160V, 480V, and 208V, depending on site and system size
  • Provide significant input to the solar, battery, and generator designs to optimize performance, reliability, and sustainability for each customer site
  • Collaborate with the rest of the development engineering team, as well as other internal stakeholders, to continually improve templates and processes and enable continuous improvement

The Ideal Candidate

  • 2+ years of experience in the design and construction of power/generation/renewable energy projects
  • Thorough technical understanding of distributed energy technologies, including some combination of solar, battery, and reciprocating engines/turbines
  • An understanding of rotating power with reciprocating engines in the 200 to 2000kw size range per engine is preferred
  • Understanding of onsite power generation, including parallel operation with the utility bus as well as with other DERs, both in grid parallel mode and island mode operations
  • Solid understanding of the utility side of the interconnection
  • Knowledge of the various DER power sources within the Microgrid and how they best interface with the utility to provide a more efficient system
  • Knowledge of emissions from the utility side, as well as each of the DERs.
  • Knowledge of systems controls for the DERs and how they can be utilized to accomplish specific operating goals while part of the Microgrid. These goals provide economic return to the customer and us
  • Strong communication skills, including the ability to communicate with technical and non-technical people to make projects work
  • A BS in Electrical Engineering is required; a focus on the power side is preferred
  • PE in power or progressing towards that license is preferred
  • Advanced courses in power or a higher-level degree in the field are preferred

This is a great opportunity to have a long-term impact on a fast-paced, private equity-backed growth business. Some of the core virtues embraced by Scales' employees include:

  • Do the Right Thing
  • Act Like an Owner
  • Hustle
  • Demand Results
  • Go Together
  • Evolve or Disappear
